The incremental model (also known as iterative enhancement model) comprises the features of waterfall model in an iterative manner. The waterfall model performs each phase for developing complete software whereas the incremental model has phases similar to the linear sequential model arid has an iterative nature of prototyping. During the implementation phase, the project is divided into small subsets known as increments that are implemented individually. This model comprises several phases where each phase produces an increment. These increments are identified in the beginning of the development process and the entire process from requirements gathering to delivery of the product is carried out for each increment.

Measurement is done by metrics. Three parameters are measured: process measurement through process metrics, product measurement through product metrics, and project measurement through project metrics.

The formal methods model is concerned with the application of a mathematical technique to design and implement the software. This model lays the foundation for developing a complex system and supporting the program development. The formal methods used during the development process provide a mechanism for eliminating problems, which are difficult to overcome using other software process models. The software engineer creates formal specifications for this model. These methods minimize specification errors and this result in fewer errors when the user begins using the system.

While selecting test cases the primary objectives is to ensure that if there is an error or fault in the program, it is exercised by one of the test cases. An ideal test case set is one that succeeds (meaning that its execution reveals no errors) only if there are no errors in the program.

Requirements of the software should be transformed into an architecture that describes the software's top-level structure and identifies its components. This is accomplished through architectural design (also called system design), which acts as a preliminary 'blueprint' from which software can be developed. IEEE defines architectural design as 'the process of defining a collection of hardware and software components and their interfaces to establish the framework for the development of a computer system.' This framework is established by examining the software requirements document and designing a model for providing implementation details. These details are used to specify the components of the system along with their inputs, outputs, functions, and the interaction between them. An architectural design performs the following functions.

The software engineering deals with three basic types of entities – processes, project, and products. A software process is a method of developing software. A software project is a development project in which a software process is used. And software products are the outcomes of a software project.

Any large project involves certain risks, and that is true for software projects. Risk management is an emerging area that aims to address the problem of identifying and managing the risks associated with a software project.

Methods for Monitoring a Project

          Time sheets

Once project development commences, the management has to track the progress of the project and the expenditure incurred on the project. Progress can be monitored by using the schedule and milestones laid down in the plan.

The design process involves developing a conceptual view of the system, establishing system structure, identifying data streams and data stores, decomposing high level functions into sub functions, establishing relationships and interconnections among components, developing concrete data representations, and specifying algorithmic details. Software design is a creative activity.

The structured analysis technique uses function-based decomposition while modeling the problem. It focuses on the functions performed in the problem domain and the data consumed and produced by these functions.
