The Influences of Strategic Information Systems on the Relationship between Innovation and Organizational Performance

The integration of information technology/information systems (IT/IS) into business strategy has been studied extensively by academics and professionals for decades (MARABELLI; GALLIERS, 2017; MERALI; PAPADOPOULOS; NADKARNI, 2012; MIKALEF; PATELI, 2017; PEPPARD; GALLIERS; THOROGOOD, 2014; TEUBNER, 2013; WARD, 2012). Seminal scientific research regarding strategic information systems (SIS) grounds studies in this theoretical context (CHAN, 2002; CHAN; HUFF, 1992; KING, 1978), with a focus on clarifying the contribution of SIS to business strategy process and content (CHEN, D.Q. et al., 2010; NEWKIRK; LEDERER, 2006; PHILIP, 2007). The academic literature reiterates that SIS and the appropriate and timely use of IT/IS effectively support the phases of strategic planning in order to maintain or gain competitive advantage and organizational

Seminal scientific research regarding strategic information systems (SIS) grounds studies in this theoretical context (CHAN, 2002;CHAN;HUFF, 1992;KING, 1978), with a focus on clarifying the contribution of SIS to business strategy process and content (CHEN, D.Q. et al., 2010;NEWKIRK;LEDERER, 2006;PHILIP, 2007).The academic literature reiterates that SIS and the appropriate and timely use of IT/IS effectively support the phases of strategic planning in order to maintain or gain competitive advantage and organizational performance (JOHNSON;LEDERER, 2013;LEIDNER;LO;PRESTON, 2011;SEGARS, A.H.;GROVER;TENG, 1998).
Thus, in this article we find that SIS facilitates business strategy process and content and has the potential to increase positive effects in the relationships among exploratory and exploitative innovation activities, ambidexterity and organizational performance.

THEORETICAL REVIEW 2.1. Exploratory innovation, exploitative innovation and ambidexterity
Developing the ability to integrate the vision, the product/service portfolio, the business processes and the implementation of strategies that meet the constant needs of the market is a challenge perpetually faced by organizations.In this regard, an organization develops the ability to create and absorb key technologies in order to promote competitive strategies through the driving action of innovation (MINTZBERG;AHLSTRAND;LAMPEL, 2009).
The term exploration in the context of the strategic role relates to the investigation of new ideas and solutions, encompassing the organizational actions of search, discovery, experimentation and risk-taking (HO; LU, 2015;MARCH, 1991).With this focus, it involves experimenting with new ideas, paradigms, technologies, strategies and knowledge, with the aim of discovering alternatives that will surpass or at least meet the needs of the market (BENNER; TUSHMAN, 2003;LEWIN;VOLBERDA, 1999;SCANDELARI;CUNHA, 2013).According to Jansen et al. (2006), exploratory innovation is based on developing strategies that will meet new demands for products and services, in a frequent cycle of reinventing the portfolio, accepting challenges to serve new markets, and developing new distribution channels and new units and production lines in order to achieve competitive advantage.Companies that position themselves with exploratory innovation practices develop the ability to frequently map the overall external environment with the aim of identifying factors that enable them to launch new products and services, in order to differentiate themselves from competitors and establish themselves as a leading company (MINTZBERG; AHLSTRAND; LAMPEL, 2009;PORTER, 1986).Companies that practice exploratory innovation thus require human, technological, and organizational capital resources (KAPLAN; NORTON, 2008) with the ability to operate in competitive environments.Exploratory innovation strategies are associated with uncertainty and greater risks of failure in implementing the strategy, but they offer superior performance gains (BENNER; TUSHMAN, 2003;KAPLAN;NORTON, 2008;MINTZBERG;AHLSTRAND;LAMPEL, 2009;PORTER, 1986;SCANDELARI;CUNHA, 2013).
The term exploitation, in the strategic context, is related to using resources, processes, and strategies to make incremental innovations, which are designed to meet the needs of current customers and markets (BENNER; TUSHMAN, 2003;POPADIUK et al., 2010).In this respect, the essence of exploitation in innovation is associated with continuous improvement of existing competencies, technologies and paradigms (MARCH, 1991).According to Jansen et al. (2006), exploitative innovation is based on improving existing products and services, with frequent and minor adjustments to the portfolio, in order to maintain and/ or expand their current customer and market share.Organizations that position themselves with exploitative innovation practices develop the ability to frequently promote actions that increase productive efficiency and effectiveness by rationalizing the use of resources and making incremental innovations to existing products and services (MINTZBERG;AHLSTRAND;LAMPEL, 2009;PORTER, 1986).Exploitative innovation strategies are associated with risk aversion and a focus on the continuous improvement of existing abilities, competencies and technologies, in order to streamline business processes (LEWIN; VOLBERDA, 1999), legitimizing the standardization and automation of the routine, with a strong appeal to the productive strategy in order to generate gains from economies of scale (GUPTA; SMITH; SHALLEY, 2006).
The term "ambidextrous organization" is described by the seminal academic literature (DUNCAN, 1976;TUSHMAN;O'REILLY, 1996) as an organization that is seeking a 'balance' between exploratory and exploitative innovation.Ambidexterity is the organizational ability to implement both incremental (exploitative) and radical (explorative) changes to enable the organization to be successful over long periods of time.Other studies, in addition to performing empirical tests on the influence of organizational performance and organizational ambidexterity in the context of technological innovation (HE; WONG, 2004;LEIDNER;LO;PRESTON, 2011;POPADIUK;BIDO, 2016), have examined ambidexterity from different conceptual perspectives, which indicated that ambidextrous organizations are capable of simultaneously exploiting competencies that already exist (exploitation) and exploring new opportunities (exploration) (BENNER; TUSHMAN, 2003;LAVIE;STETTNER;TUSHMAN, 2010;RAISCH et al., 2009).
According to Kaplan and Norton (2008), in order to achieve long-term value for shareholders, we need to understand customer performance and environmental conditions (MITHAS; RAMASUBBU; SAMBAMURTHY, 2011; YOSHIKUNI; ALBERTIN, 2014).Customer performance is measured by customer satisfaction with product and service quality, customer relationships and retention, and brand image (KAPLAN; NORTON, 2008;LEÓNSORIANO;MUÑOZTORRES;CHALMETAROSALEÑ, 2010;MOSTAGHEL et al., 2015).The organization therefore, develops competencies to perform the activities in the business value chain (PARK;LEE;CHAE, 2017;PERKINS;GREY;REMMERS, 2014;REEFKE;TROCCHI, 2013) in order to deliver the attributes requested by customers and promote satisfaction (KAPLAN; NORTON, 2008), in addition to retain those customers (SILA, 2007).Measuring the different perspectives of organizational performance is thus essential to understanding the causes of a company's financial result and their performance in terms of non-financial indicators (ALBERTIN; ALBERTIN, 2012;KAPLAN;NORTON, 2008;PARK;LEE;CHAE, 2017;YOSHIKUNI;ALBERTIN, 2017).

Strategic Information Systems (SIS)
Over the last several decades, research regarding IT/IS value creation for businesses has been intensifying (MARABELLI; GALLIERS, 2017;MELVILLE;KRAEMER;GURBAXANI, 2004;MERALI;PAPADOPOULOS;NADKARNI, 2012).An effective use of IT/IS in the business strategy was highlighted as one of the most important factors for CIOs and CEOs (JOHNSON;LEDERER, 2013;PHILIP, 2007).Studies have shown that SIS supports business strategy process and content, improving competitive advantage and organizational performance, even in highly competitive environments (CHEN, Y. et al., 2014;MERALI;PAPADOPOULOS;NADKARNI, 2012;TEUBNER, 2013).SIS is defined as a portfolio of IT/IS applications that collect, process, analyze and make data/ information available for decision making (O'BRIEN;MARAKAS, 2007;SABHERWAL;CHAN, 2001), and it exists within business strategy process and content in order to achieve business objectives.
In short, SIS incorporates the strategic planning process and facilitates the cooperation, analysis and participation of employees, enabling them to think about, analyze, deploy and follow strategic planning through the IT/IS portfolios.

RESEARCH MODEL, DEVELOPMENT OF HYPOTHESES AND CONTROL VARIABLES
Based on the existing literature, we are able to identify relationships among SIS, exploratory and exploitative innovation, ambidexterity and organizational performance, which served as the foundation for developing the study's conceptual model (Figure 1) and also raised the respective hypotheses to be tested.

Innovation and organizational performance
According to Porter (1986), companies develop specific abilities and competencies to formulate technological strategies for incremental innovations (exploitation), through cost leadership, which seek greater intensity in order to optimize processes and improve existing products; or radical innovations (exploration), through differentiation, with the ability to identify, choose and explore knowledge and technologies-external and internal-in order to offer products and services that provide a perception of value creation to the market by means of market differentiation, novelty and exclusivity.
The different approaches to innovation strategy (MINTZBERG; AHLSTRAND; LAMPEL, 2009) emphasize actions focused on accurately understanding the external environment (exploration) in order to develop new products and services, and developing internal expertise in business processes in order to achieve gains in operational efficiency and effectiveness (exploitation).
Assuming that innovation strategies are developed in order to increase the company's economic and financial sustainability through revenue and productivity growth (KAPLAN; NORTON, 2008;MINTZBERG;AHLSTRAND;LAMPEL, 2009;PORTER, 1986;SCANDELARI;CUNHA, 2013;YOSHIKUNI;JERONIMO, 2013) and that organizational performance is related to the company's ability to use internal resources in business processes (YOSHIKUNI; ALBERTIN, 2017), as well as based on previous studies in stable economies, which found that innovation influences organizational performance (FANG;LEVINTHAL, 2009;HE;WONG, 2004;JANSEN et al., 2006;SCANDELARI;CUNHA, 2013;UOTILA et al., 2009), we propose the following hypotheses: H1: Exploratory innovation is positively associated with organizational performance H2: Exploitative innovation is positively associated with organizational performance.An implicit premise in the studies by March (1991) is that organizations with superior performance seek to implement both exploratory and exploitative innovation activities.Studies that analyzed organizational ambidexterity (DUNCAN, 1976; TUSHMAN; O'REILLY, 1996) also confirmed that the best performing organizations are ambidextrous.We also identify evidence of a generally positive relationship between organizational ambidexterity and organizational performance in several empirical studies (GIBSON; BIRKINSHAW, 2004;HE;WONG, 2004;LUBATKIN et al., 2006).
Recent studies suggest that organizations should seek ambidexterity in order to increase competitive advantage and performance (LEIDNER; LO; PRESTON, 2011;SCANDELARI;CUNHA, 2013).Thus, we propose the following hypothesis: H3: Ambidexterity is positively associated with organizational performance.

Moderating SIS in the relationship between innovation and organizational performance
According to Chen et al. (2010) and Segars et al. (1998), SIS facilitates the ability to successfully execute business strategy process and content.The authors argue that business strategy success involves the company's ability to develop effective cooperative work from employees, enabling them to think about, analyze and execute the strategy supported by IT/ IS.When SIS is incorporated into the strategic planning process, it facilitates strategic awareness, promoting top-down and bottom-up communication/integration/cooperation (CHEN, D.Q. et al., 2010), without any local or global borders, in order for everyone to understand the strategic priorities (KARPOVSKY; GALLIERS, 2015;O'BRIEN;MARAKAS, 2007), thus achieving organizational commitment through teamwork (SEGARS, ALBERT H.; GROVER, 1998).
Pavlou and El Sawy (2010) found that the effective use of SIS enables a real-time perception of a company's existing resources, enabling them to adapt to transformations in the external environment.SIS enables an organization to map the external factors of the overall environment (DAMERON; LÊ; LEBARON, 2015; DAVENPORT; HARRIS; MORISON, 2010; JARZABKOWSKI; KAPLAN, 2015;NEWKIRK;LEDERER, 2006) and develop innovation strategies that capture opportunities (KAPLAN; NORTON, 2008;PORTER, 1986).
SIS supports the design stage of business strategy, allowing a company to reconfigure its existing operational capabilities to better respond to environmental changes (ARVIDSSON; HOLMSTRÖM; LYYTINEN, 2014; LEIDNER; LO; PRESTON, 2011; SEGARS, ALBERT H.; GROVER, 1998;SINGH;WATSON;WATSON, 2002), and facilitates the ability to spontaneously reconfigure existing resources during the construction of new operational capabilities and address urgent, unpredictable and new environmental situations (PAVLOU; EL SAWY, 2006SAWY, , 2010)).
SIS facilitates flexibility and agility during the formulation stage of strategic planning, enabling decision-making on strategies related to aggressiveness, analysis, proactivity, risk or risk aversion, defensiveness and innovation (CHAN; HUFF, 1992).
Thus, SIS facilitates competencies that are essential to an organization effectively developing creativity strategies and/or productivity (control) strategies as a product of the strategic planning process (CHEN, D.Q. et al., 2010).By definition, it is reasonable to conclude that when an exploratory innovation strategy is supported by SIS, it focuses on the company's creativity through the creation of new products and services and new approaches using IT/IS resources, whereas an exploitative innovation strategy focuses on the abilities promoted by SIS for control, i.e., for organizational efficiency and productivity (MARABELLI; GALLIERS, 2017; MARTINEZ-SIMARRO; DEVECE; LLOPIS- ALBERT, 2015;PHILIP, 2007).Incorporating SIS into the strategic planning process thus helps disseminate strategic awareness, analyze external factors, and promote cooperation for designing, developing, implementing and monitoring competitive strategies (NEWKIRK; LEDERER, 2006) for exploratory/exploitative innovation (MARTINEZ-SIMARRO; DEVECE; LLOPIS-ALBERT, 2015); thereby, influencing competitive advantage and organizational performance (CHEN, D.Q. et al., 2010).Therefore, we can formulate the hypothesis that a strong or weak SIS presence influences (MARTINEZ-SIMARRO; DEVECE; LLOPIS- ALBERT, 2015) the relationship between innovation strategies and organizational performance.

H4:
A strong or weak SIS presence moderates the relationship between exploratory innovation and organizational performance.
H5: A strong or weak SIS presence moderates the relationship between exploitative innovation and organizational performance.
An important study by Chen et al. (2010) contributed to the academic literature regarding SIS by identifying typologies.This study was expanded by Leidner, Lo and Preston (2011), who included an analysis of ambidexterity and provided empirical evidence of the positive relationship between SIS and organizational performance; this same study also found that ambidextrous organizations are considered to have the highest performance.Other studies related to SIS involving ambidexterity identified the organizational challenge of simultaneously 'balancing' explorative and exploitative activities, with a focus on organizational learning and innovation (MARABELLI; GALLIERS, 2017; MERALI; PAPADOPOULOS; NADKARNI, 2012).Therefore, we can formulate the following hypothesis: H6: A strong or weak SIS presence moderates the relationship between ambidexterity and organizational performance.

3.3.Control variables
Control variables (CV) are critical to management research because they simplify the interpretation of the results of statistical analyses (CARLSON; WU, 2012).Given that organizations have significant expenses and investments related to IT/IS use and management, a study performed annually by Fundação Getulio Vargas found that the services sector spent 11% of its net income in 2017, whereas the industrial sector spent 4.5% (MEIRELLES, 2018).Thus, this study uses control variables in an attempt to investigate the influences of an organization's characteristics (MELVILLE; KRAEMER; GURBAXANI, 2004)-its sector and size, based on the number of employees-on the relationship between innovation and organizational performance.

METHODOLOGY 4.1. Scale
To evaluate innovation (exploration/exploitation), we decided to use measurements and items at the level of the organizational unit, taken from Jansen, Van Den Bosch and Volberda (2006).We measured SIS using the scale by Singh (2002) and Newkirk and Lederer (2006) and specialists in the field validated it through content analysis (MORGADO et al., 2018), and the reliability, validity and parsimony of the items were confirmed, as recommended by Wieland, Durach, Kembro and Treiblmaier (2017).We used the scale to measure organizational performance (KAPLAN; NORTON, 2008), proposed by Yoshikuni et al. (2014), for the dimensions of financial performance, market, internal process, and learning and growth.For the innovation and SIS items, we need to perform translations and consult with subject specialists, who made semantic modifications in order to make it comprehensible without compromising the validity of the content.All the latent variables had at least three items, which made it possible to measure them adequately according to the recommendations of Hair, Hult, Ringle and Sarsdest (2013).
Specialists in the field of strategy (researchers and professors) and IS, who had more than 10 years of experience, evaluated the research questionnaire.The evaluation of the instrument was positive and showed that the questionnaire represented the perception of the variables used in the scales.
We evaluated all the items using a 7-point Likert scale, ranging from 1 (strongly disagree) to 7 (strongly agree).The full scale with the constructs, assertions (variables/indicators), and their factor loadings is available in Appendix I of this study as supplementary material.

Data collection
We selected a sample from the directory provided by the Center for Applied Information Technology (Centro de Tecnologia de Informação Aplicada -GVcia) at the São Paulo School of Business Administration (Escola de Administração de Empresas de São Paulo -EAESP), Fundação Getulio Vargas (FGV).We chose the respondents based on their position, experience and professional knowledge (KIM et al., 2011), and they provided reliable information about the characteristics of the group or organization; they included senior business managers with appropriate knowledge of IT/IS and strategic business processes.
We administered the study via email through the distribution of 1353 invitations to organizations, of which 256 (19%) responded to the questionnaire using a form available on the Internet.The sample size met the requirements for partial least squares path modeling (PLS-PM) (HENSELER; RINGLE; SINKOVICS, 2009; URBACH; AHLEMANN, 2010).Of those who responded to the questionnaire on behalf of their respective organizations, 39% were presidents, directors or superintendents, 36% were managers or coordinators, and 25% were supervisors with decision-making power.
Table 1 describes the composition of the companies included in the sample in terms of the sector in which they operate and the number of employees.
As observed from the data presented in Table 1, 93% of the sample was composed of companies in the services and manufacturing sectors, and 40% of the sample was composed of organizations with more than 500 employees.

Analysis
After evaluating the descriptive statistics of the demographic variables, the scale was modified using confirmatory factor analysis (convergent validity, discriminant validity and reliability).
We estimated the analytical structural model using PLS-PM by analyzing common issues involving the simultaneous analysis of multiple variables, for example, with asymmetric variable distribution or limited data (RINGLE; SARSTEDT; STRAUB, 2012), using the SmartPLS 2.0 M3 software package for all analyses (RINGLE; WENDE; WILL, 2005).

Measurement model
We defined the dimensions a priori based on the theoretical reference and were maintained for confirmatory factor analysis.
After eliminating two items that had a factor loading less than or equal to 0.5 in addition to high cross-loadings (lack of discriminant validity), the convergent validity of all the constructs was considered adequate, with items greater than 0.707, and all the constructs presented an average variance extracted greater than 0.5 (HENSELER; RINGLE; SINKOVICS, 2009; RINGLE; BIDO; DA SILVA, 2014).We find the values on the diagonal (square root of average variance extracted) to be greater than the values outside the diagonal (correlations), and thus, there is discriminant validity (HAIR et al., 2013).The reliability is also adequate, with composite reliability values greater than 0.7, as can be observed from Table 2 (HAIR et al., 2013;ROUHANI et al., 2016).
From Table 2, we can observe that the organizational performance (OP) constructs (1, 2, 3 and 4) are correlated (0.46 to 0.58), which confirms the possibility of using them as indicators for a second-order construct.The second-order OP variable produced an average variance extracted of 0.642 and a composite reliability estimate of 0.93.In a comparison of the Fornell-Larcker criterion with the square root of average variance extracted values of the OP variable (0.801), the criterion was revealed to be satisfactory.

Structural Model
The operationalization of the model was complex because it involved evaluating the moderating effect of SIS and the control variables, in addition to including a latent variable to eliminate common method variance (i.e., the measured latent marker variable, hereafter the MLMV method).We apply the MLMV approach by Chinn W.W. et al., (2013) to control common method variance.Specifically, four items were designed to have the lowest possible logical correlation with the other constructs under investigation (see Chart 1).Therefore, we analyze the model in more than one case (Table 3), and we discuss those results in the following sections.
In case 1, the relationship between exploitative innovation and OP was 0.307 (p<0.001), and in case 2, without the latent variable (MLMV), it was 0.291 (p-value < 0.001); we conclude that the common method variance was minimal (0.02), and the result of case 2 will Table 2. Matrix of correlations between the first-order constructs be used to discuss hypotheses H1 and H2.Therefore, hypothesis H1, which presents the relationship between explorative innovation and OP, did not present statistical significance, with a p-value > 0.05.Hypothesis H2 was supported and presented the influence of exploitative innovation on OP (0.291; p-value < 0.001).
To verify hypothesis H3, we classify ambidextrous organizations as those with a value higher than the average for the explorative and exploitative innovation variables, in a total of 103 cases; we create the ambidexterity (interactive term) variable by cross-multiplying all the standardized items of the explorative and exploitative innovation variables (CHIN, WYNNE W;MARCOLIN;NEWSTED, 2003;LEIDNER;LO;PRESTON, 2011).Hypothesis H3 is supported, as the influence of the relationship between ambidextrous organizations and OP is statistically positive and significant on performance (0.377; p-value < 0,001).
SIS presented an influence on the dependent variable (case 2; 0.524; p-value < 0.001), indicating moderation of the variable in the relationship between innovation and OP (CARLSON; WU, 2012).Thus, to test hypotheses H4 and H5, we create heterogeneous databases to evaluate the differences in structural coefficients between groups (HAIR et   al., 2013) in the relationship between innovation and OP.The groups classified in case 3 ("weak SIS presence") have averages less than or equal to 4 points (100 cases), and those in case 4 ("strong SIS presence") had averages greater than 4 points (156 cases).
The relationship between explorative innovation and OP in both cases 3 and 4 does not present statistical significance (p-value > 0.05), and thus hypothesis H4 is not supported.However, the relationship between exploitative innovation and OP presented statistical significance in both cases 3 and 4 (0.289; 0.413; p-values < 0.001), confirming hypothesis H5.Comparing the path effects between the SIS groups, we observe a significant variation of 0.125 (30%).
To evaluate hypothesis H6, we separate the database into two groups.The first is the group of ambidextrous companies with a strong SIS presence (99 cases), which presents positive and significant effects on performance (0.359; p-value < 0.001; R2 = 12.6%).Given the insufficient size of the second group, ambidextrous companies with weak SIS (only 4 cases), we are not able to verify the relationship's effects or statistical significance, and therefore, the hypothesis is partially supported.
Using the data, we are able to perform additional analyses regarding the influence of SIS on the relationship between innovation and OP.First, independent groups of companies are classified as having a strong presence of exploratory (46 cases) and exploitative (210 cases) innovation activities, moderated by a strong or weak SIS presence.Next, the relationship between exploitative innovation and OP is analyzed for groups with strong (158 cases) and weak (52 cases) SIS, and the path effects are positive and statically significant (strong SIS; 0.557; p-value < 0.001; R2 = 31.1%;and weak SIS; 0.339; p-value < 0.05; R2 = 11.5%),presenting a difference of 0.22 (39%) between path coefficients.Then, we perform the same analysis for the relationship between explorative innovation and OP for groups with strong (37 cases) and weak (9 cases) SIS.For the strong SIS group, the effect on the relationship between explorative innovation and performance is positive and statistically significant (0.453; p-value < 0.001; R2 = 20.5%);however, as there are only 4 cases for the weak SIS group, it is impossible to statistically test the relationship.
The sector and number of employee CV presented no statistically significant effect (p--value > 0.05) on the OP construct, and they were extracted from the model in order to remove their effect on the relationships of interest to this study (CARLSON;WU, 2012).
As indicated by the values of R2 listed in Table 3, the determination coefficients indicate that the relationship between innovation and OP has a large effect (HAIR et al., 2013).

DISCUSSION
The testing of hypothesis H1 (exploratory innovation -> OP) did not present statistical significance; this result differs from those of other studies on innovation (MARTINEZ-SIMARRO; DEVECE; LLOPIS- ALBERT, 2015;UOTILA et al., 2009).However, in a specific analysis of the group of 37 companies with a strong presence of exploratory innovation activities and a strong SIS presence, the relationship between exploratory innovation and corporate performance had a positive and statistically significant effect.This analysis allows us identifying-in a group restricted to the 14% of companies with a strong SIS presence-the influence of the relationship between exploratory innovation activities and OP, in line with other studies regarding SIS (LEIDNER; LO; PRESTON, 2011;XUE, LING;RAY;SAMBAMURTHY, 2012).
The testing of hypothesis H2 (exploitative innovation -> OP) provides support to confirm that innovation has a more substantial influence on an organization's performance under conditions with a strong SIS presence.The study shows that companies that use SIS intensively in business strategy processes have a 30% higher contribution to achieving OP.The result was expanded, and we found that companies with a strong presence of exploitative activities and a strong SIS presence have a 39% higher influence on OP than companies with a weak SIS presence.We believe that incorporating SIS into the strategic planning process facilitates the content of exploitative innovation strategies, thereby allowing the company to regularly implement small adaptations in its portfolio of products and services, making itself present in its local market, expanding its relationship with the customer and improving its efficiency and effectiveness in business processes.The results are in line with studies performed at Brazilian companies by Yoshikuni and Albertin (2017), who found that IT/IS are intensified to make productivity gains through operational efficiency and effectiveness.
The testing of hypothesis H3 (Ambidexterity -> OP) is supported (0.377; p-value < 0.001) and shows that 40% of the companies in the sample develop ambidextrous activities, confirming that not all companies develop this ability (DUNCAN, 1976;LEIDNER;LO;PRESTON, 2011).
Hypothesis H4, which tested a strong or weak SIS presence in the relationship between exploratory innovation and OP, is not supported in the complete sample.However, in a group of companies (37 cases) with a strong SIS presence and a strong presence of exploratory innovation, we find a positive and statistically significant association with OP.This relationship identifies that the stronger the SIS presence, the greater the contribution of exploratory innovation to OP.
Hypothesis H5, which tested a strong or weak SIS presence in the relationship between exploitative innovation and OP, is supported.A strong SIS presence shows a 30% higher contribution to the path coefficient for the relationship between exploitative innovation and OP, when compared to a weak SIS presence.For a group of companies (158 cases) with a strong SIS presence and a strong presence of exploitative innovation activities, there is a 40% higher contribution to the path coefficient for the relationship between exploitative innovation and OP, compared to a weak SIS presence.This relationship signifies that the stronger the SIS presence, the greater the contribution of exploitative innovation to OP.
Hypothesis H6 is partially supported, as the group of companies with a weak SIS presence is insufficient for the statistical test (4 cases).However, the study shows that a strong SIS presence has a positive and statistically significant contribution to the relationship between ambidexterity and OP.This relationship means that a strong SIS presence is one of the determining factors for organizational ambidexterity.

CONCLUSION
The study made it possible to identify different impacts of a strong or weak SIS presence on the relationships among the variables of innovation (exploitation and exploration), ambidexterity and organizational performance.In the research method, we use the PLS-PM statistical approach with the SmartPLS software, which appears to be an appropriate tool for analysis in the study.
The study's main theoretical contribution is that a strong SIS presence increases the influences of innovation (exploitation and exploration) and ambidexterity on organizational performance.
An additional contribution to management practices is that when SIS is incorporated into the strategic planning process through a portfolio of IT/IS applications, it enables organizations to develop radical innovation activities (exploration), with an emphasis on strategies for launching new products/services, focused on reaching emerging customers, markets or distribution channels; and incremental innovations (exploitation), by adapting and enhancing existing products and services, and their productive capabilities, designed to meet the needs of existing customers.This article also makes practical contributions, demonstrating that organizations should carefully examine how SIS can benefit their phases of strategic planning by enabling innovation focused on improving organizational performance.
This study is limited by the method used to collect the data.The sample is not probabilistic, and the results obtained for a given population cannot be generalized.
