Software development is more than simply an analysis, architectural construction, design, code writing, and testing process. There are many versions available, depending on the needs of the client and the details of the project:
Materials and time
The Time & Materials approach entails paying for the finished product based on labor expenses. The quantity of work is not paid for by the client. He reimburses the contractor’s team for the man-hours spent on software development and installation.
It operates as follows:
- The project is divided into tasks. The team examines each job independently so that the customer may make any changes while the work is being done.
- The project team reviews the first job and gives statistics, such as the number of man-hours required to complete it.
- The task’s cost is calculated by multiplying the number of man-hours by the developer’s travel time.
Advantages of the Time and Materials Method
- Adaptable requirements. The task is done in brief bursts and leads to the MVP.
- Hourly rates are available.
- Customers pay the hourly rate that was established at the outset. When the task is finished, the customer pays for it.
- Product excellence. In a few cycles, the team tests and enhances the product.
- Transparency. Customers may follow development using the model, while developers deliver work-in-progress reports.
The disadvantages of the Time & Materials method
- Indefinite terms.
- The budget is not specified. The cost is an estimate.
- Costs of resources. The consumer is responsible for managing their own time and wants.
- Difficult choices. The market is changing; the design or functionality implemented at the start of the project is irrelevant at the conclusion.
Use of the Time and Materials model
Time & Materials is ideal for medium- to long-term projects, particularly those that use flexible approaches. The Time &Materials model is appropriate for testing, bug eradication, maintenance, or refining projects.

The Fixed Price model is used when the development budget and the specific deadline for project completion are established before the start of work and stay constant. The contractor bears the risk of late completion of work.
Advantages of the Fixed Price Strategy
- Time constraints. Developers may create a clear strategy and set deadlines after the client knows what functionalities he needs in the program.
- Predictability. Everything is discussed and planned by the client and the contractor.
- The Fixed Price model is best suited for small projects with specific needs and restricted capabilities.
Cons of the Fixed Price Approach
- Improvements. All changes that have not been reviewed from the start should be subject to a separate agreement and paid for separately.
- Misunderstanding risks.
- Such initiatives have limited scalability, and there is a strong likelihood that they will fail.
- Market developments. It is difficult to make simple adjustments in future projects.
Use of the Fixed Price model
This method is preferred by the public sector and pro-government businesses. The methodology is also appropriate for MVPs and projects with tight budgets and deadlines. Of course, this is ideal for small projects with evident functionality, since they will not alter in the future (at least for 1 year).

This paradigm is best suited for long-term collaboration. The whole team is accessible to the customer for as long as is required. Furthermore, while constructing long-term projects, this technique saves money. The team structure, the number of experts, and the work schedule are all determined by the client.
Advantages of a Dedicated Team Approach
- Only one project. The crew is focused on a single project.
- Control. The client has complete control and management of the team and may change each member’s task.
- Professionalism. Individual approach to specialized selection. Ability to choose the proper professionals based on their degree of expertise and experience in a certain subject.
- Cost-cutting measures. A remote group checks deadline adherence.
The disadvantages of the Dedicated Team approach
- Long-term endeavor. Long-term and sophisticated projects are often implemented by a specialized crew.
- There might be a time gap between a consumer and a team.
- Instructions. A remote team may develop a project based on its tastes, which is not always desirable.
Use of the Dedicated Team model
Appropriate for applications requiring adaptable software development. Perfect for situations when the consumer wishes to know the expenses ahead of time. However, the project’s needs and scope often alter or are unclear.
