We are experienced in both Waterfall & Agile Methods and Coding Standards. The Agile methodology treats the time-to-market as the most important feature while Waterfall methodology treats the collective feature set as the most important. Our team can adapt to work in either method, depending on your situation and requirements.
Waterfall Software Development Model
The Waterfall Model is the most common version of a Software Development Life Cycle (SDLC) for software development. It is called the Waterfall Model because it defines a rigid and linear development method, where each phase is completed before the next one is started and there is no loop back. It follows the principle of doing things right the first time. Every time.
This model is preferred when the requirements are clearly and visibly outlined. Complete project execution is divided in to well defined stages of analysis, design, development, testing & QA, release & user acceptance and finally followed by maintenance and support. Typically a schedule is set with deadlines for each stage of development at the start of the project. In theory, this model leads to the project being delivered on time because each phase has been planned in detail. Practically this model involves high risk as it does not embrace the inevitable changes and revisions that become necessary with most of the projects. Once an application is in the testing stage, it is very difficult to go back and change something that was not thought of in the analysis stage.
Agile Software Development Model
Agile software development processes are built on the foundation of iterative development. To that foundation we add a lighter, more people-centric viewpoint than traditional approaches. Agile processes use feedback, rather than planning, as their primary control mechanism. The feedback is driven by regular tests and releases of the evolving software.
The development team and customers agree a set of requirements and a project schedule upfront. The development is planned as a series of separate phases (also called iterations or sprints) allowing incremental delivery of product features.
Within a sprint, new product features are planned, designed, implemented and tested. At the end of each sprint, the new features are demonstrated or delivered to the customer. The activities for the next sprint are then planned and a further iteration is performed. This increases confidence on the part of the customer because they can see visible signs of progress.
Software Coding Standards
Software coding standards are language-specific programming rules that greatly reduce the probability of introducing errors into your applications, regardless of which software development model (agile, waterfall, eXtreme programming, and so on) is being used to create that application.
Software coding standards originated from the intensive study of industry experts who analyzed how bugs were generated when code was written and correlated these bugs to specific coding practices. They took these correlations between bugs and coding practices and came up with a set of rules that when used prevent coding errors from occurring. Coding standards offer incredible value to software development organizations because they are pre-packaged automated error prevention practices; they close the feedback loop between a bug and what must be done to prevent that bug from reoccurring. You don't have to write your own rules to get the benefit of coding standards - the experts have already done it for you.
In a team environment or group collaboration, coding standards ensure uniform coding practices, reducing oversight errors and the time spent in code reviews. When work is outsourced to a third-party contractor, having a set of coding standards in place ensures that the code produced by the contractor meets all quality guidelines mandated by the client company.
