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 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.

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 output of the requirements phase of the software development process is Software Requirements Specification (SRS) (also known as requirements document). This document lays a foundation for software engineering activities and is created when entire requirements are elicited and analyzed. SRS is a formal document, which acts as a representation of software that enables the users to review whether it (SRS) is according to their requirements. In addition, it includes user requirements for a system as well as detailed specifications of the system requirements.

Design is essentially the bridge between requirements specification and the final solution for satisfying the requirements.  The goal of the design process is to produce a model or representation of a system, which can be used later to build that system. The produced model is called the design of the system. The design of a system is essentially a blueprint or a plan for a solution for the system. The design process for software systems often has two levels.

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.

The development of software starts with the requirements document, which is also used to determine eventually whether or not the delivered software system is acceptable. It is therefore important that the requirement specification contains no error and specifies the client's requirement correctly.

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.

The purpose of the software quality assurance plans (SAQP) is to specify all the work products that need to be produced during the project, activities that need to be performed for checking the quality of each of the work products, and the tools and methods that may be used for the SQA activities.

When tasks are defined and schedules are estimated, the planning effort has sufficient information to begin staffing plans and organizing a team into units to address the development problem. The comprehensive staffing plan identifies the required skills and schedules the right people to be brought onto the project at appropriate times and released from the project when their tasks are complete.
