STRATEGIC CLARITY AND PERFORMANCE OF ENERGY SECTOR STATE CORPORATIONS IN NAIROBI CITY COUNTY, KENYA
Main Article Content
Abstract
The purpose of this study was to examine the influence of strategic clarity on performance of energy sector state corporations in Nairobi City County, Kenya. The study employed the correlational cross-sectional survey research design to test noncausal relationship between the study variables without the researcher controlling any of them. The target population consisted of 126 senior and middle managers of the 4 energy sector state corporations in Nairobi City County, Kenya. The proportionate stratified random sampling technique was used to select a sample size of 96 senior and middle managers of the 4 energy sector state corporations in Nairobi City County, Kenya. A self-administered structured survey questionnaire was used to collect primary data. A cross-sectional survey-based approach was used to collect primary data. The study utilized the drop and pick method. The collected data was coded, edited and entered into the Statistical Package for Social Sciences (SPSS) version 26 to create a data sheet that was used for statistical analysis. The descriptive statistics were used to compute, summarize the data in respect to each variable and describe the sample’s characteristics. The Pearson’s product moment correlation analysis was performed to confirm or deny the relationship between the study variables. The correlation results indicated that goal clarity and role clarity had positive and significant relationship with the performance of energy sector state corporations in Nairobi City County, Kenya. A standard multiple linear analysis was performed with the performance of energy sector state corporations as the dependent variable and goal clarity and role clarity as the predictor variables. The regression results indicated that goal clarity and role clarity had positive and significant influence on the performance of energy sector state corporations in Nairobi City County, Kenya. The study recommends that managers and practitioners should consider a holistic reassessment and implementation of strategic clarity to foster the performance of energy sector state corporations. The policymakers should consider initiating a review of the existing policies to motivate the managers and practitioners to consider a holistic reassessment and implementation of strategic clarity to foster the performance of energy sector state corporations. Future research should examine the influence of strategic clarity on firm performance with environmental turbulence as a moderator in other sectors or contexts.
