These systems integrate its proprietary operating system software with hardware supplied by major manufacturers, and are sold to small, medium and large-sized companies for a range of business applications. Its systems are distinguished by a sophisticated operating system, which permits use without trained data-processing personnel.
Requirements analysis[ edit ] In the requirements analysis phase, the first business plans software development in the verification process, the requirements of the system are collected by analyzing the needs of the user s. This phase is concerned with establishing what the ideal system has to perform.
However it does not determine how the software will be designed or built. Usually, the users are interviewed and a document called the user requirements document is generated.
The user requirements document will typically describe the system's functional, interface, performance, data, security, etc. It is used by business analysts to communicate their understanding of the system to the users.
The users carefully review this document as this document would serve as the guideline for the system designers in the system design phase.
The user acceptance tests are designed in this phase. See also Functional requirements. There are different methods for gathering requirements of both soft and hard methodologies including; interviews, questionnaires, document analysis, observation, throw-away prototypes, use case and static and dynamic views with users.
System design[ edit ] Systems design is the phase where system engineers analyze and understand the business of the proposed system by studying the user requirements document.
They figure out possibilities and techniques by which the user requirements can be implemented. If any of the requirements are not feasible, the user is informed of the issue. A resolution is found and the user requirement document is edited accordingly.
The software specification document which serves as a blueprint for the development phase is generated. This document contains the general system organization, menu structures, data structures etc.
It may also hold example business scenarios, sample windows, reports for the better understanding. Other technical documentation like entity diagrams, data dictionary will also be produced in this phase. The documents for system testing are prepared.

The baseline in selecting the architecture is that it should realize all which typically consists of the list of modules, brief functionality of each module, their interface relationships, dependenciesdatabase tablesarchitecture diagrams, technology details etc.
The integration testing design is carried out in the particular phase. The designed system is broken up into smaller units or modules and each of them is explained so that the programmer can start coding directly.
The low level design document or program specifications will contain a detailed functional logic of the modulein pseudocode: The unit test design is developed in this stage.
Validation phases[ edit ] In the V-model, each stage of verification phase has a corresponding stage in the validation phase. These UTPs are executed to eliminate bugs at code level or unit level. A unit is the smallest entity which can independently exist, e. These tests verify that units created and tested independently can coexist and communicate among themselves.
Test results are shared with customer's team. System Test ensures that expectations from application developed are met. The whole application is tested for its functionality, interdependency and communication. System Testing verifies that functional and non-functional requirements have been met.
Load and performance testing, stress testing, regression testing, etc. Test Plans are composed by business users.

UAT verifies that delivered system meets user's requirement and system is ready for use in real time.Non-software options for business plan creation Software doesn’t always have to be the solution.
