How we work

Engagement models

The right commercial model depends on who directs the work, who is accountable for the result and how certain the scope is. Here are the eight we work with, and a short tool to help you narrow the choice.

The eight models

  • Statement of work

    A contractual engagement defining scope, deliverables, responsibilities, acceptance criteria and commercial terms.

  • Time and materials

    Delivery based on agreed resource rates and actual authorized effort.

  • Fixed-price project

    A defined scope delivered for an agreed commercial amount, subject to change control.

  • Hybrid delivery

    A combination of onsite, remote and contractually authorized distributed delivery.

Which model should we discuss?

Six questions. You get one to three models worth talking about, with the reasons. Your answers stay in your browser.

This tool runs in your browser and needs JavaScript. Without it, contact us and we will walk through the same questions with you.

A statement of work is the contract that sets these terms. It can sit under any of the models above. Each engagement is different, and the written terms decide.

Questions people ask

What is the difference between augmentation and managed project delivery?

In augmentation you direct the work and own the result. In managed project delivery we are responsible for agreed deliverables under a scope, with acceptance criteria.

Can we combine models?

Yes. A common pattern is a fixed-price discovery phase, followed by time and materials for the build, then managed services for support.

When is fixed price a bad idea?

When the scope is likely to change. Both sides then spend their effort arguing about change requests.

Do you offer all eight?

We discuss which fit your situation. Some, such as managed services, depend on the type of system. We tell you plainly when something is not a fit.

Is the tool a quote?

No. It suggests models to discuss. Quotes come from a scoped conversation.
