Process of developing of program software is referred as physical design Programmers or developers are responsible for documenting the program. In UML diagrams, Use cases, Class diagrams, Sequence diagrams, Structure diagrams etc can be used.ĭevelopment: The Coding part starts here.UML Diagrams: It provides a ready-to-use and expressive visual model.

Write the procedures that tell how to process data and produce output.It describes the data to be inputted, calculated or stored.It’ll describe how proposed system will work. Here functionality of the proposed system is designed. Usually 4 to 6 people participate.įacilitated Session: Gather a set of common requirements from a group in a faster manner than taking interview each of them separately. Group Interviews: To get richer set of requirements in a shorter period. One-to-one Interview: Sit down with client and ask them what they need.

Questionnaires: Helpful when we have to gather input from dozens, hundreds or thousands of people. Types of requirement gathering technique: It is the process of collecting the requirements. Requirement Gathering: It is difficult to make a solution if you don’t know the problem. There must be scopes for profit after the successful Completion of the project. Economical Feasibility: It evaluates the cost of the software development against the benefits gets from the developed system. The proposed system must have high operational feasibility.ģ. Operational Feasibility: It tests the operational scope of the software to be developed. Technical Feasibility: It compares the programming languages, hardware resources available in the software development and the programming language and hardware resources required for the development of the product.Ģ. It makes analysis of different aspects like cost required for developing and executing the system, the time required for each phase of the system and so on.ġ. It determines whether the project under analysis is achievable or not under the organization’s resources and constraints.

It represents all the activities required to make a software product transit through its life cycle phases.įeasibility Study: A feasibility study decides whether or not the proposed system is worthwhile.

It encourages the development of software in a systematic and disciplined manner.

It is the set of activities or phases that analysts, designers and users use to develop & implement in a system.

A framework that describes the activities performed at each stage of a software development project.
