The main types of Engagement Models in IT

Before you start developing any IT products, you can choose the pricing principle and the type of interaction with contractors. This is all done based on the needs of the project. For example, one model, due to its flexibility and other features, may be suitable for startups, but for more complex projects, you have a completely different approach.

Therefore, to choose the right cooperation model for it staff augmentation, you need to know more detail about each of them. In this article, we will look at the advantages and disadvantages of each model, as well as find out which methodology will be suitable for the project.

Time and Material Project

Let's start with one of the most common work models, called the Time and Material Project. The bottom line is that the price for the entire project will be based on the time spent by the team. Also, the cost of materials for the development of the project affects the price. It is suitable for projects where it is difficult to determine the exact cost from the very beginning. It is usually used for small projects where no more than 3 specialists are required.


  • In the process of work, the client can change the work plan or requirements and this will not give any inconvenience to the contractor;
  • This model goes well with agile methodologies;
  • Result tracking. You will be able to observe the process, make adjustments and interact with the team.


  • You cannot determine how much you will have to spend at the end of the project, because everything depends on time and materials;
  • You will need to communicate a lot during the project and manage the work process.

Dedicated Team

The essence of this methodology is that a specific team will work on your project. The price will be affected by the salary of each team member and other additional costs.

A key feature of the Dedicated Team is the ability to form a team based on the skills and abilities of each participant and the budget of the project. This type is perfect for large and long-term projects, where the main requirements for the project are not monitored.


  • Full control. The customer will be able to fully control the work process and manage the team;
  • Individual approach. Each specialist will be selected based on their experience and knowledge, which will make it possible to find real professionals;
  • Cost reduction. This technique allows you to reduce waste because it controls the additional recruitment and deadlines.


Lack of details. Sometimes a team lacks clear instructions on how to proceed with a process and may act on their guesses. It doesn't always end badly, but the cases are different.

Fixed price

As you can guess from the name of this method, a specific price for certain company services has already been set here. It is best to use this interaction model for short-term projects.


  • Clear requirements and clear results;
  • Setting specific deadlines, which allows you to get the job done on time.


  • Lack of flexibility. The price is set for specific services, so the client will not be able to make any changes or changes during the project.

Agile value

Agile value is one of the modern types of interaction, which is based on the company's costs. The entire workflow is usually divided into sprints. Suitable for any type of project, because it is based on the individual needs of the customer.


High efficiency. You can easily make any changes to the project;

Full control. The client sets tasks and goals and also controls their implementation, which allows you to get the desired product in the end.


Time. It will take you a long time to agree on all the details in this type of interaction.

Which type to choose is up to you. For example, if you need a long-term large project that should be developed along with Angular, then a dedicated team may be a good fit for you. It all depends on the details of the future product.
