Bespoke Software Built Around Your Business
Vardells’ team of certified software developers bring extensive technical expertise and real-world understanding to every project. We’re PRINCE2® Practitioner, PRINCE2 Agile® and ITIL® certified, with hands-on experience delivering scalable, tested, and secure applications tailored to retail, wholesale and enterprise environments.
Workshops
To ensure we are capturing the customer’s specific requirements we recommend that we have departmental workshops at the appropriate time. These workshops will enable the Vardells team to present and where possible demonstrate the core functionality of the module applicable to that department. Throughout the workshop we can discuss and documents idea and core requirements. If we receive too many ideas, we may ask you to MoSCow them to understand the priority.
MoSCoW Analysis
To prioritise and sequence the backlog of stories to be implemented, it is planned that Bestway.
Retail will carry out MoSCoW (Must, Should, Could, Won’t Implement) analysis on the proposed functionality to identify which stories can be pushed to the tail end of the project and which must be completed early on.
The Vardells Software Development Philosophy
We approach development with a mindset focused on user needs, constant feedback, and continuous improvement. Every project is built around stakeholder involvement and transparency.

Use of Test-Driven Development and Continuous Integration
Scrum Methodology
The project could be managed using the Agile Scrum methodology. Scrum provides a framework that gives a high level of focus on the tasks in hand and promotes ownership of individual tasks, whilst offering a flexible and and collaborative approach. The following diagram illustrates how Scrum projects are managed
Development
At Vardells, we have adopted a Test-Driven Development approach to the construction of the stories. Unit tests will be written as the first part of the solution and the development will not be complete until all the unit tests for the story are passing.
Once the developer has completed the above, they will commit the changes into the Vardells source code repository so that they are version controlled. The act of doing this will invoke our continuous integration environment to build the application and execute all the unit tests across the whole application. This provides an automated regression test at unit level to check that dependent functionality has not been impacted.
If the continuous integration environment flags that the build has been negatively impacted or tests are seen to fail, then action is taken immediately to rectify the situation. The resolution of any issues identified in a continuous integration test is normally achieved in just a few hours.
If a sprint task is particularly complicated, then programmers may pair up to validate the coding as it is being done. Otherwise, in most cases, a quick review by a senior team member is factored into the sprint.
Testing Without Compromise
The Scrum approach provides a much closer relationship between the development and testing processes undertaken in software development; more so than in the traditional methodologies. The developers and testers work in a team where continuous discussion and review occurs through daily stand-ups. This leads to a quality approach and fast issue identification before the code reaches the test environment. The agile approach provides an inbuilt requirement testing strategy by providing the team and product owner with the opportunity to discuss and clarify requirements and their context in real time.
Due to the rapid nature of the development, the use of automation is fundamental to providing test cases which are realistic, effective and repeatable. It’s planned by using tools such as Selenium, so the testers can build their test cases to confirm the development in a test-driven nature, improving the coverage, speed and effectiveness of the process.
Within the sprint, as well as designing functional tests which can be used though the continuous improvement function, the testers build a suite of test cases to confirm the requirements are met. These are created in a test management tool and visibility is given to the stakeholders of all automated and manual test runs to allow full transparency of the work undertaken. This provides a clear indication of the quality of the system at any point in the development.
