What is a fixed price and scope project

A fixed scope project is a software development model where requirements, deliverables, timeline, and budget are agreed upfront before development begins. It works best when the scope is clear, priorities are unlikely to change, and you need a predictable path to delivery with minimal deviation during execution.

When to Choose this model


A fixed scope project is the right choice when you need predictability across budget, timeline, and deliverables — and when the project can be clearly defined before development starts.

Your requirements are stable

You already know what needs to be built, and the scope is unlikely to change significantly during delivery.

You Prefer a Waterfall Approach

You want a structured project with clearly defined phases, milestones, and limited changes once execution begins.

You need to move faster

When timelines are tight and internal capacity isn’t enough to hit key milestones.

Predictability matters more than flexibility

You want all major project decisions made upfront to reduce uncertainty during development.

Longer Time-to-Market Is Acceptable

You are willing to invest more time in planning and validation to gain greater clarity and control before launch.

Security and Change Control Are Critical

This model is especially suitable for projects where iterative changes are limited and governance, compliance, or approval processes require tighter control.

Proven Results from Fixed Scope Projects

See how clearly defined scope, structured delivery, and predictable execution help teams launch digital products with confidence. These examples show how fixed scope projects work when requirements are known upfront.

A clearly defined scope and structured delivery enabled Sela to launch a web and mobile experience for Via Riyadh under tight deadlines.

How THIS MODEL works

01

Discovery Phase

We start by understanding your business goals, project context, and requirements in depth. Even when SRS or BRD documentation already exists, this phase helps validate assumptions, uncover missed details, and define features, functionality, and deliverables more precisely.


02

Planning

Based on the discovery findings, we create a clear project roadmap with timeline, milestones, and resource allocation. This ensures all stakeholders are aligned before execution begins.


03

Design

We translate requirements into wireframes, mockups, and prototypes that visualise the final product. This helps align stakeholders early and refine the user experience before development starts.


04

Development

Our team builds the product according to the agreed scope and specifications, following established coding standards and engineering best practices to ensure a robust and scalable solution.


05

Testing

We validate the product against the defined requirements through functional, security, and performance testing. This ensures the solution is reliable, secure, and ready for release.


06

Deployment

We move the product into a live environment, configure the infrastructure, and ensure all components work together as expected so launch happens smoothly.


05

Continuous Support

If a support agreement is in place, we continue with maintenance, regular updates, and fast issue resolution to keep the product stable and effective after launch.

FAQ

What is the difference between fixed scope and time and materials?

With fixed scope, the requirements, budget, and timeline are agreed in advance. With time and materials, the scope can evolve over time, which gives more flexibility but less predictability.


What happens if requirements change during a fixed scope project?

Any changes to the agreed scope are handled through a formal change request process. This includes impact assessment on timeline, budget, and deliverables before implementation. Minor adjustments may be accommodated if balanced within the existing scope, but larger changes require re-estimation.


How involved do I need to be during the project?

Your involvement is highest during the discovery and planning phases, where requirements are defined and validated. During development, involvement is typically reduced to milestone reviews, feedback, and approvals.
