• Fixed Price   Model

• Time & Material Model

• Dedicated Team Model

• Mixed Price Model

Generally the model is appropriate for small projects or big projects developed in several fix price iterations.

• indicates clearly what is to be delivered, when, and what the costs will be (on-time, on-budget delivery of projects)

• offers customers a low-risk option, and is most effective when the scope and specifications of the software application development project are reasonably clearly defined

Generally the model is appropriate for long term projects where the scope of the work may change. Offers high flexibility for the team.

• is desirable when scope and specifications for the project are not defined explicitly 

• total effort cannot be estimated in advance and the scope of work can be changed during the development

• offers assigned project teams with the required team members, project managers, equipment and infrastructure based on project requirements

• offers the flexibility to balance team size and project workloads

• customers pay a monthly charge based on the total effort reported by the team for each month  and accepted by the client

• also in this case there is a continuous control of the time, budget, deliverables – (project plan, project monitoring, quality gates, etc.)

Generally the model is appropriate for long term partnerships where the dedicated team may be allocated on different projects for the same client.

• offers team members working only on the client projects and dedicated 100% to its projects

• provides a completely exclusive approach to customer's needs and maximum cost efficiency for its business

• flexible engagement contract

• skilled staff to work exclusively for the client

• possibility to select team members, motivate and manage them

• experienced dedicated team leader to ensure the most efficient workflow

• permanent direct contact

• transparent workflow

This model is a swinging between fixed price model and time&material model, determined by the project modules characteristics or the project iterations complexity.

• applied on projects with a considerable number of modules or iterations

• tailor-matches the project modules characteristics: if a module has clear specification and no risk estimation, then the fixed price model is likely to be chosen, otherwise a time & material model is applied

• provides a completely exclusive approach to customer's needs

• flexible engagement contractual form
