The Three Models of Software Development Process

Software development processes are approached differently by different IT Solutions companies across the world. But, what matter the systematic approach and also the understanding of the trends of the market. These two aspects need to go in tandem with each other.

A Model for Software Development Process is not new to Software Engineers. But the resources i.e. the tools and techniques for these processes have definitely added to the efficiency of following these models of software development.

The Three Models of Software Development Process

The Waterfall Method

It originates in the manufacturing and construction companies for very structured physical environments which can indirectly affect the hardware oriented model which was adapted for software development. Software Developmentexperts prefer using this methodology for medium or large sized software development projects.

The waterfall method is sequential design process used for software development processes. It goes in progressive fashion but only downwards like a waterfall through the different phases of requirements, design, implementation, test and delivery. Waterfall method offers a model that is comparatively lower in risk and it runs in linear flow. The very initial phase is about eliciting and collecting the requirements to be able to conceptualize the solution. In this process, the users and stakeholders document, validate and approve of a set of functional performance and other such requirements. There are many phases in the waterfall model which are formally documented. This model is application to businesses that are static.

But while before selecting this model, you need to ensure that the end user’s environment is stable, the risk and cost are associated along with aspects like schedule, security which many may be the small but important requirement in the requirements document. This model offers a practical approach for dealing with clients and acts in interest of faster approvals.

The Spiral Method

Software Development With Spiral Method

Known as the risk driven process model for software development projects, it is based on unique risk patterns. The spiral model helps the software engineers to adopt the elements of one or more development process and thus makes software development much more comprehensive and prepared for evolutionary prototyping.

The spiral model will be able to reduce the project risk initially and also request capability faster. In many projects, the requirements may be partially known and then rest will be known while the project evolves. In this case, the project can begin with this model as the remaining requirements will be known as the project proceeds. The cycle in the model follow the similar process as the waterfall model but it can also generate a usable prototype. The work starts with CONOPS and life cycle planning where the successive loops include high level requirements, software requirements, design and development, testing etc.  

The model signifies a cycle a progressive model where the software works outwards. The software development specialist can collect the data of the requirements at the beginning and update the model after completion of every cycle. Also, the stakeholders can analyze the risks and accordingly create strategies for reducing the factor of risk. With this model, the project can be ended anytime as and when the client suggests that the requirements are met with and can be solution can be made operational without any hurdles.

The Agile Model

Agile Methodology Software Development

Among the most popular methods for software development is Agile Model. This model is used to develop a system for iterations that rance 2-4 weeks. The model uses stories as the planned inputs to sprints. Basically, Agile requirements can be written down in non technical stories. This model avails better comprehension of the solution for the technical and the non technical personals.  

The documenting in this process focuses on what has been already done and give a foresight on what can be done. The documentation needs to the meet the three pointers of the criteria:

·         Essential (minimalism)
·         Valuable (needs)
·         Timely (stipulated time)

The development efforts are required on the small and very specific capabilities. The good practices of agile projects are short cycles, collaboration with partners, tight team work and streamlined communication among the software development experts. Agile environment provides support whenever required. You can expect your solution requirements to evolve with the help of functional specifications, meeting minutes, test cases, calculating metrics and also the progress reports. For cost effective software solutions build with Agile Methodology, Outsourcing Software Development India is a great option.
