Cooperation Models

Choosing the right cooperation model affects delivery speed, budget control, and how flexible you can be with changes. Below are the most common ways we work with clients, with simple rules and clear expectations.

What type of cooperation would you choose?

Fixed Price
Best when scope and requirements are clear and stable. You get an agreed budget, milestones, and defined deliverables.

Time and Material
Best when priorities evolve. You get flexibility, continuous delivery, and full transparency into time spent and progress.

Dedicated Team
Best for long-term product development. You get a stable team that works as an extension of your organization.

Fixed-Price Model

Best for
Websites, landing pages, e-commerce projects, redesigns, and feature sets that can be fully described upfront.

Typical project size
Small to medium

Typical duration
1-3 months (depends on scope)

How it works
We agree on scope, milestones, acceptance criteria, and a release plan. Any changes are handled through a change request flow so expectations stay aligned.

Pluses

• Fixed budget and defined outputs
• Clear timeline tied to milestones
• Predictable planning and delivery
• Less management overhead on the client side

Minuses

• Less flexibility when requirements change
• Requires more detailed scoping upfront
• Changes may affect timeline and cost

Common stages of a fixed-price project

• Project initiation (up to 7 days)
• Scope definition and agreement (up to 20 days)
• Team assembly and planning (up to 6 days)
• Design and prototyping (up to 24 days)
• Development and testing (up to 60 days)
• Delivery and closure (up to 10 days)

Time and Material Model

Best for
Products with changing priorities, roadmap-driven development, continuous improvements, and ongoing support with new features.

Typical project size
Any size, often medium to large

Typical duration
Ongoing, delivered in monthly or sprint cycles

How it works
You pay for the actual time spent. Work is planned and delivered in a steady cadence with full visibility in the tracker and regular demos.

Pluses

• High flexibility and fast iteration
• Easy reprioritization without contract friction
• Transparent tracking of progress and effort
• Ideal for long-term product growth

Minuses

• Budget needs active management
• Scope is shaped continuously
• Success depends on clear prioritization and fast feedback

Typical delivery rhythm

• Backlog grooming and planning
• Weekly demos or sprint reviews
• Release-ready increments on a predictable schedule
• Documentation updated as the product evolves

Dedicated Team

Best for
Long-term product development, scaling delivery capacity, and building stable velocity across releases.

Typical project size
Medium to enterprise

Typical duration
3+ months

How it works
A dedicated team works as an extension of your organization. Roles are stable, product context grows over time, and delivery becomes more predictable each month.

Pluses

• Stable team and deep product knowledge
• Faster execution without repeated onboarding
• Strong ownership of architecture and quality
• Easy scaling with additional roles when needed

Minuses

• Requires active roadmap ownership
• More responsibility on the client side for priorities
• Not ideal for short one-off tasks

Research and Development (R&D)

Best for
Validating feasibility, de-risking architecture, choosing a tech stack, confirming performance and security assumptions.

Typical duration
2-6 weeks

What you get

• Technical options with tradeoffs
• Architecture draft and key decisions
• Risk list with mitigation steps
• Prototype results and recommendations

Proof of Concept (PoC) Development

Best for
Testing one or two critical uncertainties before committing to a full build.

Typical duration
2-4 weeks

What you get

• Working prototype for validation
• Feasibility confirmation
• Next-step plan toward MVP
• Rough estimation for full delivery

MVP Development

Best for
Launching the first real version to users with only the essentials, then iterating based on feedback.

Typical duration
4-10 weeks (depends on scope)

What you get

• Core user flows and key features
• Basic analytics and tracking setup
• Release plan and handover notes
• Backlog for the next iterations
