Product lifecycles influence supply chain management. Supply chains may be composed by, designed around, and modified for products. Existing studies have advanced product management and product lifecycle management literature through dimensions of product innovation, product proliferation, product line extensions and new product development. Product deletion, rationalization, or reduction research is limited but is a critical issue for many reasons. Sustainability is an important reason for this managerial decision. This dissertation work, grounded in multiple literature streams from both marketing and supply chain management, identifies relations and propositions to form a firm-level analysis. Interviews, observational and archival data from international companies (i.e.: Australia, China, India, and Iran) provide empirical support as case studies through a grounded theory approach. Bayesian analysis, an underused empirical analysis tool, will be utilized to provide insights into this underdeveloped research stream. Gibbs sampling and reversible jump Markov chain Monte Carlo (MCMC) simulation are used for Bayesian analysis using collected data. The integrative findings are exploratory but provide insights for a number of research propositions.
