Chapter Overview of Software Process Models and Descriptive Criteria for their Analysis In this chapter, we present an overview of the process models that will be detailed in the following chapters. Depending on their focus, these models have been divided into two groups: activity-oriented and people-oriented models. Also we describe the criteria used to analyse the models, which will serve to ascertain their advantages and disadvantages. 2.1. SOFTWARE PROCESS MODELS The parameter used here to classify the process models is based on defining what process elements the model covers. Specifically, the models analysed have been classified as shown in Figure 2.1. The Activity-Oriented Models focus on defining the functions, activities and information of the software process management, development and/or supporting processes. The People-Oriented Models focus on defining the people involved in the software process and their relationships. These two model categories are further divided into two alternatives depending on the goal for which the model was developed: Descriptive Models Prescriptive Models. 28 Descriptive Models are mainly concerned with specifying a process now used within an organisation or with representing a proposed process to be able to predict some process features. Descriptive models answer the question, "How is software now
