The Cronbach Alpha was calculated to confirm the reliability of the study construct. The reliability coefficient obtained was 0.82 and the data generated were analyzed using mean and standard deviation scores. The researcher used Person Product Moment Correlation to test the stated hypotheses. Findings reveals that product life cycle is significantly associated with time varying advertising elasticities of product brand. The study conclude that to fully adopt product life cycle and the varying advertising elasticities dimension as key strategies for business cycle growth and continued survival.
