MES Engagement Models

Software solutions can be implemented through four Engagement Models – Fixed Duration, Time & Materials, Full Time Equivalents (Offshore) and Full Time Equivalents (Onsite). So, choosing the right mode of engagement is the most critical of all business decisions and can result in the right mix of expenses and yields.

Fixed Duration / Cost

Software development projects that are built around a fixed budget, timeline and cost, are referred to as Fixed Duration projects. For small to mid sized projects where the end-user is the buyer of a product or a service, this is the most common of all delivery methods.


Opt for the Fixed Duration Engagement Model if:

Time and Materials (T&M)

Projects that are contracted for a delimited (or open ended) number of hours are referred to as Time & Materials projects. With such projects, tasks are mapped to total number of hours spent on that task; detailed reports for ‘hours spent’ outline and enable authenticity and cross-verifications.


Opt for the Time & Materials Engagement Model if:

Full Time Equivalents (FTE)

Full Time Equivalents is an IT staffing solution wherein our personnel are assigned to and are dedicated to your project and therefore, designated by us for your responsibilities and purposes alone. Personnel can be software engineers, project managers, software testers, software analysts or consultants. If the FTE resource performs tasks from our development center, the corresponding delivery sub-model is referred to as an Offshore FTE Resource. If the FTE resource performs tasks at your (or at your client’s location), such personnel are referred to as an Onsite FTE Resource.

Difference between T&M and FTE
Although these may seem similar (and in a few cases, they are similar), T&M and FTE Engagement Models have a fundamental difference between them.

For engagements under an FTE Engagement Model, the singular determining aspect or factor is the FTE resources/personnel who are dedicated to your purposes for a specified duration of time (typically specified for ‘n’ months and gradually extended). In other words, the FTE resource so designated and deployed, execute their roles only for the customer (you) that they are deployed for.

For engagements under a T&M model, the deliverables hold more relevance than the personnel who are executing the task. For example, you may wish to engage with us for 200 hours of work that involves say, 100 hours of software programming, 50 hours of testing and 50 hours of documentation. However, to execute these tasks for you, we will likely have separate personnel for each of these tasks. It is also likely more than one personnel might execute portions of each of the tasks, especially in situations where quicker delivery (turn-around) times are required.

In other words, the FTE is associated with resources and their output; the T&M Engagement Model is associated with Materials delivered within specified time.
