At crewlogix we follow a process oriented development methodology designed to minimize project risks and development time. We focus on business solutions that fulfill business goals, instead of merely providing technical solutions.

The approach that we adopt is the spiral iterative methodology, where the project goes through one or more iterations of all project stages. The above presentation gives a brief overview of the process.

We have defined processes for requirements capture, analysis, design, development, testing and deployment. We generate UML diagrams representing the Use Case Model, Analysis Model, Design Model, Implementation Model and Test Model.

In this stage, client requirements are gathered. This is done on the basis of information provided by the client in the form of documents, existing systems & process specs, on-site analysis interviews with end-users, market research and competitor analysis. This stage has the following steps:

• Requirements Analysis with Business Application Goal and High Level Requirement gathering
• Creation of Visual Scope Document and Feature List
• Providing technical recommendations and High Level Requirement Specification

In this stage, a detailed analysis is carried out from the information in the vision & scope document and feature list. This stage has the following steps:

• Analysis and creation of Software Requirement Specification
• Creation of Use Case Specification & Diagram and generating the Use Case Model
• Design business rules and flow diagrams
• Establishment of Requirement Traceability Matrix
• Validation of the Scope and estimates against the contract and revisions made if necessary

In this stage, the application design is developed on the basis of the software requirement specification, use case specification, business rules & diagrams and the scope agreed upon in the Requirement Definition stage. This stage has the following steps:

• Designing Architectural Diagrams
• Creation of High Level Design and Low Level Design class diagrams
• Establishment of Entity Relationship Diagram, Data Flow Diagram and Deployment Diagram
• User Interface - The prototype is developed and validated against the requirements
• The use cases elaborated in the analysis model are represented using collaboration diagrams
• Design model elaborations are made from the analysis model.
• The Implementation Model is generated from design
• The Test Model is generated from use cases

In this stage, the actual code based on the design is created and tested against design requirements and test cases. This stage has the following steps:

• The development of code base proceeds as per implementation and design models
• The application source code is tested according to the test cases and test plan
• Documentation of processes
• Creation of Use Case Test results

• In this stage, the developed application is tested through test cases.
• Integration and quality testing is carried out resulting in test reports.
• Client acceptance tests carried out.
• Client feedback and debugging.
• Client acceptance.
