Now that you have decided to outsource your project, you have another big thing to decide and that is the engagement model with the vendor. A software development engagement model is a framework that governs how a vendor provides IT or Software Services. In this fast-paced era, the demand for tech-savvy and top-notch software development continues. Since every brand’s requirement is unique to their organisation, there cannot be a particular engagement model for software development that fits all. So the success of software development outsourcing models depends on a suitable engagement model too. That is why brands must be first aware of the various types of engagement models that exist in software industry & they should know the pros & cons of every model & then decide on the right one which suits their business requirements. The engagement model depends on various factors like size, duration, budget & scope of the project.

Types of IT Engagement Model

Many outsourcing software development companies in India propose a fixed price, T&M, and dedicated team models. Let’s learn which IT engagement model is apt for each situation.

1. Fixed Price Model 

This model refers to thorough planning, time, scope, and materials to be used. Based on this, the entire project development budget is decided. This particular model is often preferred by projects with a specified scope budget. In case of extra work (new features, add-ons, or services that haven’t been specified before), clients and software development providers tend to make additional contractual agreements.


  • No Price Fluctuations – The customer knows from the beginning how much he needs to spend & the vendor company needs to follow strictly the timeline as scope & time are fixed. Both the party need not cover additional costs but only what is outlined in the agreement.
  • Lower Risk Factor – According to the fixed cost project model, the price for developers’ work is stable if there is a detailed specification. Once the agreement is assigned, there is a strict deadline for the project delivery.


  • Lack Of Flexibility in requirement – The model isn’t suitable for projects that need flexibility in requirements as once the agreement is approved by both sides, nothing can be changed.

2. Time & Material 

Time and material is yet another engagement model in IT where the budget communicates the resources and time utilized for the project development. Here, the client pays for completing the tasks instead of guessing them beforehand. It’s wise for a software development provider to have proper know-how about the several changes involved in the process. Contrary to the fixed cost model, the T & M agreement possesses a more flexible schedule and budget. The client has access to control the resources spent on the present task and can make the necessary changes if needed. In this model, client has the flexibility to book a certain amount of hours of resources monthly for a certain period of time for their work.


  • Uncertainty in project requirements is effectively handled.

3. Dedicated Team

Dedicated team IT engagement model implies that the software service provider offers their specialists to the customer based on their skills, competencies, and tech stack as per the project’s requirement. This type of IT engagement model is suitable for long-term emerging projects. You don’t require firm planning and it enables the client to switch and shift requirements, timeframe, budget, resources, and team size of any particular project. You also have full control over the implementation of your project. In this engagement model, it’s up to the customer to choose project management whether they will manage the dedicated team themselves or involve a project manager from the software vendor’s side. While the focus is on high-quality delivery, the pricing model is also very simple as per the dedicated team’s size and hourly rates of each resource involved. All you have to mind is monthly salaries and extra costs like service provider’s fee, administrative needs, etc. which are decided during the terms of the contract, as this will make up the billing.


  • Hiring a dedicated team from an outsourcing software development company is much cheaper than recruiting in-house resources.
  • No training and hiring costs, and it is easy to scale the team.
  • The team involved in the project will be focused only on your project.


  • The model is not efficient for short-term projects.
