Abstract

The paper examines the impact of Managerial decision making process on Organizational Performance attainment with a study of Nigeria Breweries plc Lagos and Guiness Breweries Nigeria plc Lagos. The study adopted an empirical survey method with a view of eliciting relevant data for analytical purpose so as to answer several questions and attain the objectives of the study. Both primary and secondary sources of data collection were utilized for the study. Specifically for the primary source, five-point liker traiting scale questionnaires were used in obtaining the opinions of the respondents (i.e. strongly agree, 5, agree, 4, undecided, 3, disagree, 2, and strongly disagree, 1). Two hypotheses were formulated and analyzed using Multiple Regression test. The study findings revealed that managerial decision making process adopted by Breweries firm i.e. programmed decision, non-programmed decision, and group decisions amongst others have impacted on the performance output of the organization in Nigeria. Second, finding revealed that judgment shortcuts, systematic biases, errors allowed by decision makers and managers have significantly distorted quality of managerial decision making processes on Performance attainment for the two Breweries manufacturing companies. The judgment shortcuts, errors are; overconfidence bias, conformation bias, anchoring bias, availability bias, randomness error, winners curse, hindsight bias, base rate bias, loss aversion bias and risk aversion bias amongst others. The study recommendation is that for appropriate decision making process, managers should endeavor to obtain appropriate and adequate information before embarking on decision process if good results are to be obtained from the decision outcomes and to avoid distortion and errors that would emanate at the end of the day. Secondly, decision makers and managers should practice transparency, fairness, equity and honesty base practices and apply them in all their dealings religiously such that the quality of the decision made would stand the taste of time and enable high performance output attainment by Breweries manufacturing organization.
