Step1.
30-minute connect call.
We start by getting to know you, your company and your web app requirements on a free 30-minute connect call.
Step2.
Get your web app proposal.
If we feel there’s scope for us to work together, we’ll send across your web application proposal, outlining the budget, addressing any key questions, and breaking the process down into key stages.
Step3.
Discovery workshops.
The project begins with a structured session to define app objectives, streamline functionality, and address potential issues. Following this, we’ll identify user types and create personas, understanding their goals and usage scenarios. With user personas in hand, we’ll develop ‘user stories’ for each feature, addressing technological approaches and challenges.
Step4.
Design and prototype.
In the design phase, we prioritise UX design, ensuring a smooth interface built around your users’ needs. We’ll provide wireframes, designs, and a style guide for developers. We also ensure branding aligns with your main brand. We then create a fully clickable and testable prototype.
Step5.
Build sprints.
We utilise Agile development, as used by tech leaders like Google and Microsoft. Agile involves two-week ‘sprints,’ prioritising user-centric ‘stories’ for quick progress and feedback. This approach enables rapid adaptation to changing project needs
Step6.
Quality assurance.
Our application code adheres to best practices, emphasising reliability and reusability. We prioritise robustness through systematic processes, including source control, Test Driven Development (TDD), Continuous Integration (CI), and Continuous Deployment. This ensures a rapid, automated workflow with comprehensive testing. Our software meets the rigours of some of the most demanding compliance teams in the world.
Frequently asked questions
What is your project management process?
Your web app development project will begin with a kick off call where we’ll establish roles and responsibilities, utilising Gantt charts to ensure everyone involved is aware of the expectations on how long each stage should take. You will be assigned a dedicated project manager who will remain in regular contact, as well as being able to request access to our project management tool where you can leave comments and offer your own insight.
We also take an “agile” approach to any web app development project. This involves using an ‘Agile Development’ methodology, whereby the add the app steadily evolves in over several two-week sprints. Each sprint consists of different site features, known as ‘stories’, and each story is given priority depending on its value and importance. You will receive a demo of the end of each sprint, giving us the chance to report progress and gather feedback. Such an approach allows us to rapidly prototype and adjust to any changes in the brief as we go.
How will we communicate during the project, and how often will updates be provided?
Regular catch-up meetings can be arranged with your project manager and the core team members working on your web app. You also have the freedom to reach out to your project manager with any queries you might have throughout the process, and can utlisies NexWeby urgent email if you have an important request that must be handled imminently.
How do you approach the design and user experience (UX) aspects of web app development?
NexWeby’s experienced designers will use a collaborative tool called Figma to create a prototype of your web app, providing a clear picture of the design, layout, and functionality. The prototype will be user tested throughout, helping to identify areas that require alterations and optimisations to provide the best experience possible when it comes to launch. Prototyping will be carried out in line with the Agile Methodology, allowing us to efficiently implement any changes.
What is your process for testing and quality assurance?
There’s no point spending valuable time and resources developing a web app if you don’t test it until the latter stages only to realise it requires significant changes. That’s why we embed testing and quality assurance throughout the development process, ensuring that everything is to your taste and functioning as it should be before we move on to the next stage.
