5. Flexible Engagement Models

You need to evaluate the project your requirements and see what is more suitable for your project. Different engagement models are having different pricing. In general, there are:

(a) Fixed Price Model:

While addressing a software development company, you have an idea about your budget. In this case, the fixed-priced model will suit you the most. 

In this model, there is already a predefined budget as well as a schedule. This means you and the Java development team agree on a fixed cost that you will be paying after the successful delivery.

While keeping this in mind, you can enjoy the below benefits of this model:

• A transparent and predictable development process

• The fixed priced project has to be completed within the agreed time without any delays, no matter what. 

Tip: This engagement model is best for small projects having a limited budget and clear deliverables.

(b) Time & Material Model:

Unlike the fixed price model, this one offers way more flexibility in terms of budget and project requirements. The total cost, as well as the scope, is not known until the project completion. This entirely depends on the actual time and effort that is used to implement it.

• When planning is in progress, this model allows you to change the project milestones on the go. 

• There is increased flexibility as it follows the ‘pay as you go‘ approach.

• There are constant supervision and active involvement of everyone in the project throughout the process.

Tip: Good fit for product improvement and technical support.

(c) Dedicated Team Model

A dedicated app development model has the best features of Fixed Price, Time & Material model. You have an offshore development team by your side that has your project usually for a long term basis. 

The model aims at compensating for the lack of necessary skills and expertise within the in-house team members. You can either manage the complete team or hire a project manager who will be responsible for the full coordination. 

Having a straightforward pricing model, the dedicated model is the best of both worlds. There is a service fee that depends on team size and is billed monthly. The advantages of the model:

• Predictable and transparent budget

• Flexible project scope

• Complete control of the team

• Java developers are completely dedicated to your project

Tip: You can reap the benefits of the model even if you want to make changes in the middle of the process.  

Based on the aforementioned, you can then decide to hire developers on an hourly, part-time, or full-time basis.
