How Fixed-Fee Waterfall Delivery Works

A Fixed Plan Delivered for a Fixed Price

Our Waterfall project development process follows a structured, sequential approach. This method involves defining the entire project requirements at the outset, quoting for it, completing the work, and then releasing and maintaining the final product.

This approach is best suited to customers who require a fixed-price project delivery, rather than prioritising agility and the ability to adjust requirements on a month-by-month basis. Typically, we plan and estimate the project upfront before contracting based on that plan.

Structured and Predictable Project Planning

At the beginning of each waterfall project, we conduct comprehensive planning and requirement-gathering sessions with all stakeholders.

This thorough upfront planning stage clearly defines your project's scope, timelines, and deliverables. It reduces risks, prevents scope creep, and ensures alignment from day one, giving you clarity, control, and confidence throughout the development lifecycle.

Reliable, Phased Development Process

Our waterfall development process proceeds in clear, well-defined phases, allowing systematic and efficient progress tracking.

Each stage, from initial build to testing and deployment, is carefully managed and documented, with clear milestones and approval checkpoints. This ensures maximum transparency, quality assurance, and predictability throughout your project's lifecycle.

Testing and Quality Assurance

Quality and reliability are at the heart of our waterfall approach. Each app undergoes a comprehensive QA process before final delivery, starting with internal testing before being released to you for User Acceptance Testing. Our approach ensures that your app is robust and meets your specifications as outlined in planning.

Frequently Asked Questions

Waterfall development is ideal for projects with clearly defined requirements, fixed budgets, and timelines, such as corporate apps or startups looking to build their very first app with tight budgets that cannot afford scope change mid-way through.

Project duration depends on complexity and scale, but clear phases and structured processes mean we can provide reliable timelines upfront, typically ranging from several weeks to several months.

Typically, we recommend delivering a brand-new project within three to six months. If it's shorter than that, it's likely a small project. If it extends beyond six months, you may be defining too many requirements upfront. In that case, consider a minimum viable product approach—streamline phase one to launch something smaller, leaner, and sooner, allowing you to test early assumptions.

Ideally, with the Waterfall approach, changes are not made mid-development with the Waterfall approach. Sometimes, we can accommodate changes when necessary, but it's not ideal—it's inefficient and can disrupt the project timeline and budget.

If you require flexibility to make changes during development, we recommend the Agile project delivery approach over Waterfall. The Waterfall method is best suited for projects where requirements are locked in before development begins.

Absolutely—we provide regular updates, milestone reviews, and complete transparency at every stage, ensuring you always know the project's status.

We offer ongoing support, maintenance, and further enhancements to ensure your app remains updated, secure, and effective after launch. The support and maintenance approach we recommend will depend on your needs. For example, apps with greater scale and user growth may require a different support and maintenance arrangement than those without.

What Our Clients Say

  • Scorchsoft helped us take our idea for an app and make it a reality. Everything from the planning meeting to decide what we really needed to the project management and execution was great. It was delivered on time - early in fact - and on budget. Highly recommend.

  • I'm really pleased with how my app came out, it was exactly what I was looking for. The team at Scorchsoft are great at what they do and made the whole process as simple and easy as possible. Being someone who is not very tech savvy the set up and back end operations were done in a great easy to use manner even for myself which makes using my app stress free. Thanks to all the team!

  • The new Flourish Education website has already removed a lot of manual processes, freeing up both schools, candidates and internal employees time. We are delighted with the look and feel which is clean, professional and more engaging. We are also pleased with the decision to have an HD video background on the homepage, and building immediate trust with our clients by giving them a taste of what it looks like in the Flourish Education offices.

    James HancocksMarketing Manager, Flourish Education
  • I can't believe how quickly we started to see results with this project. Scorchsoft provided us with graphic-designed mockups of how the app would look once built, and we were able to sell the product for use by our first customer before the product was finished. Since launching in March, we have secured a major television network as a client who now uses Image Approvals to manage the talent approval process for their productions.
