Explanation of Solution

System development methodologies:

System development methodology can Standardize across entire enterprise using the below three methodologies.

• Spiral methodology
• Agile methodology
• RUP methodology

Spiral methodology:

This methodology is a combination of iterative development and sequential linear development methodology.

This methodology consists of set of framework activities. Every framework activity denotes one unit of spiral path. The most importance phase in this methodology is risk analysis.

The phases in agile methodology are planning, design, construct, evaluation.

Phases in the spiral methodology:

• Planning:

This phase initially begin with the collection of business requirements. This phase contains the understanding of system requirements by common conversation between the customer and the analyst. The product is planned at the final spiral process.

• Design:

This phase contains the architectural and logical design of the module. It also contains the final design in the following spiral.

• Construct:

This phase develops the final software product at each spiral process.

• Evaluation and risk analysis:

Risk analysis contains recognizing, evaluating, and examining methodological feasibility such as plan slippage and price overrun.

Agile methodology:

This methodology targets the customer satisfaction by delivering the software components quickly and continuously to the customer. This process carried over by an iterative process, which uses minimum requirements.

The phases in agile methodology are planning, requirement analysis, designing, building and testing.

Rational Unified Process (RUP) Methodology:

This method targets the customer needs by delivering the high quality product. This methodology improves the team productivity.

Gates of RUP methodology:

This methodology used for separating the software development into four gates. Each gate contains the repetition of the software process in development.

This methodology develops the product in numerous stages based on response from the stockholders. The four gates is are inception, elaboration, construction, transition

• Inception:

The idea of proposed system identified in this phase. This phase verifies if each stockholder shared the idea of given proposed system and required resources.

• Elaboration:

The developer explains the architecture and needed resources of the given system.

• Construction:

The development of the given product completed in this phase. Moreover, the product design and source code are finished in this phase.

• Transition:

The modifications are done in this phase. Here any modifications or updates are prepared based on user feedback.

Comparison to traditional waterfall approach:
