During my final year I wrote a dissertation on Conceptual modelling for a software application. I started my research reading white papers and I came across the requirement analysis process. During the development of a critical software careful analysis needs to be undertaken and for this reason, Software teams carry out different activities that belong to a Software Development Life Cycle.
A software development life cycle has different phases. The most popular phases in the software development life cycle includes the Planning, Analysis, Design and Implementation. When developing a software application it is important to follow this phases in an iterative and incremental manner. The process of following the SDLC in this method is called Agile. This is because no task in the SDLC is followed sequentially. This doesn’t mean that an Agile process has no structure. Instead, Agile teams carry out their tasks independently of what product is needed for the next phase. For example: when an agile team begins a new project the analysis might begin without a full project plan and as the project moves further to next phase, a clear picture of the project plan begins to emerge.
Having a project plan is really important, however, when a software team has no full picture of the business requirements a model is developed so that some analysis can be performed on it.
Analysing the requirements of a web application can take place in many forms. These include joint interviews, JAD sessions and questionnaires. At the end, the work product should be a system proposal containing the business requirements that satisfy the business model of an organisation. If the business need for your organisation is to accept orders online then this requirement should be included in the business model for the new system proposal.
Constructing a proposal is a tedious process most especially when working with UML diagrams. Nevertheless, an organisation can facilitate this task by asking the right questions most especially at the beginning to help you determine the feasibility of the project. If a project is deemed feasible both technically and economically then the project is most likely to gain approval by all major stakeholders of the project.
At Niniwebsites, an E-commerce project actual cost is around £1,499 and it could take about 30 days to add about 300 to 500 products with Woo commerce. This includes, project initiation, documentation and implementation of a WordPress Theme of your choice.

That’s all the hard work done for you and for any custom templates you might need it might cost around an extra £1000 pounds for the Photoshop design before the actual implementation of your desired custom design.
In conclusion, an e-commerce website may cost you anything from £1,499 to £3,000 depending on your requirements.
