Project scope and complexity
The size and difficulty of a project is one of the key factors to consider when choosing an engagement model. A fixed price model provides clarity and predictability for small projects with well-defined scopes and minimal anticipated changes but is not a good choice for a time-consuming and technologically tricky project.
Projects with evolving requirements, lengthy timelines, and considerable complexity are a much better match with the time and materials or dedicated team models. Small and medium-sized software projects would work well with a fixed-price model. Short-term and middle-sized projects are a match for the time and materials model. The best choice for long-term software development is a dedicated team model.
Client's budget and timeframe
Clients with predefined budgets and strict timelines may prefer fixed-price models, while those seeking flexibility to accommodate evolving project requirements might favor time and materials or dedicated team models. The time and materials model offers flexibility. However, estimating the overall budget in advance is challenging, potentially leading to budget overruns. While seemingly costly at the get-go, a dedicated team model may boast lower costs in the long run and save you some budget in hiring costs.
Flexibility and adaptability needs
Navigating risks, and adapting to unforeseen challenges in the fast-paced world of information technology is crucial. If being flexible and scalable is what your projects needs to thrive, then you might want to consider what each engagement model brings to the table in terms of flexibility and adaptability.
Fixed price models, with their structured plans, are suitable for projects with well-defined scopes. However, their limited adaptability to unforeseen changes may pose challenges in responding to unexpected developments.
Time and materials models offer high flexibility for evolving requirements, making them ideal for projects with changing scopes. Nevertheless, strong communication is essential to manage changes, and effective management is crucial to prevent budget overruns.
Dedicated team models shine in terms of flexibility and scalability, particularly in long-term projects. Their long-term adaptability and focus on risk mitigation make them suitable for projects where uncertainties may arise during extended development periods.
Level of control and involvement
An important point to consider is the client's inclination towards control and involvement in the project management process.
Fixed price models may provide a sense of control through predefined specifications, whereas dedicated team models offer direct oversight and management capabilities.
A dedicated team model is beneficial for a client with a technical background and a preference for active involvement in day-to-day project management. It allows the client to maintain high control and engagement throughout the development process.
Fixed price models provide a structured plan with predefined specifications, reducing the need for daily involvement from the client and thus offering a more hands-off approach.
Time and materials models empower clients with active control over project direction, allowing real-time adjustments. However, this flexibility comes at the cost of increased client involvement, influencing the overall control dynamic.
