Product Life Cycle and Assessment Parameters

The paper presents a review of some important articles about the product life cycle. The phases of the entire cycle are specifically defined, from product development to its use and elimination. On the basis of this phase definition, a concept of unified assessments is elaborated, which essentially defines the characteristics of both the product and the external influences on its life cycle. The main phases are presented, as well as the use of specific fields that essentially supplement the assessment of a product's suitability during individual product life cycle phases. The design parameters are used and supplemented with constraints during the product conquering phase. Specifically, product parameters during the phase of product use are presented as the key elements of assessment. Finally, the product elimination parameters are also used for assessment. Costs are included as well; these are specific to each product phase and need to be discussed separately. All the three product phases form the basis of a comprehensive assessment. The division to three separate product life cycle phases and definition of parameters for validating the product's characteristics constitute a significant contribution to a fuller understanding of the product life cycle process.
