System Development Life Cycle: Implementation

Implementation

Although the term is used synonymously with “development”, the term of implementation tries to provide a more holistic view than just developing the software. This phase combines all the modules together into the training environment that detects errors and defects. A test report which contains errors is prepared through test plan that includes test related tasks such as test case generation, testing criteria, and resource allocation for testing. In this phase we also integrate the information system into …

Water Fall Model

This is like the “Kindergarten” level of every software development study. This particular software development model is very simple to understand. In fact, it is so simple that it is even found to be away from reality. Let us explore this foundational approach of SDLC.

Waterfall Model – This was the first Process Model to be introduced. It is also referred to as a linear-sequential life cycle model. As mentioned before, it is very simple to understand and apply. In a waterfall model, each phase must be c…

Water Fall Model: Royce՚s Original Waterfall Model

Royce՚s Original Waterfall Model

Keeping in with Royce՚s original waterfall model, we have a total of Six phases as presented in the following order,

1. Requirements – The first phase involves understanding what needs to be design and what is its function, purpose etc. Here, the specifications of the input and output of the final product is studied. The Requirements Understanding Document is the tangible output.

2. System Design – The requirement specifications from first phase are studied in this phase and system design i…
