Which Project Development Model  Sets You Upart For Success

What your project is about is very important. Even more important is how the development company makes it.

Why?

If your project is ever-changing, growing, and adapting, but the development is set in stone, then your product is outdated until it reaches the end users.

If your project requirements are set in stone and you need it early, but the development mode is flexible, you end up wasting precious time, adding things to your product that you didn’t need to.

TST Technology provides adaptable engagement models customized to the objectives and working style of every client. From fixed-scope builds to agile collaborations or pay-as-you-go services, we offer the appropriate mix of control, transparency, and delivery, whether for startups creating MVPs or businesses spearheading innovation.

TST Technology Work Models Explained in Detail

Fixed Scope Product Model

The Fixed Scope Product model is designed for customers who have a clearly defined MVP scope and would like to have a one-time project with fixed, unambiguous requirements. With this model, you can validate your product in the market with preset time, efforts and money (you can switch to a different model once your requirements change). 

Once the Software Requirements Specification (SRS) is signed off, the project scope is frozen, encouraging predictability and control over timelines and budget. Any deviations after this involve a new estimate and formal approval, ensuring transparency and mutual agreement along the way.

Key points of this model are:

  • TST Technology assigns the team, so clients do not choose individual resources.
  • A project manager is included to manage the project and report at significant milestones, but there is limited day-to-day management and responsive planning.
  • The working approach is a milestone-based waterfall process, with the project going through set stages with deliverables met at each milestone.
  • Client visibility is provided through milestone reports instead of daily or sprint-by-sprint reports.
  • Pricing is on a formal 40%-20%-30%-10% milestone payment schedule, tying payments to project progress and deliverables.
  • Deliverables include the entire product cycle from UI, development, QA, DevOps, to deployment.

This model works best for projects with a well-defined, fixed scope where requirements are unlikely to change dramatically. It is ideal for teams or startups looking to create an MVP with a clear, measurable budget and schedule.

Additionally, it suits those who prefer traditional project management approaches, featuring less continuous change and comprehensive milestone reporting for greater predictability and control.

Monthly Agile Team Engagement

The Monthly Agile Team Engagement model is intended for clients who require long-term collaboration with the flexibility to continuously refine their product. It permits scope adjustments and feature prioritization on a sprint-to-sprint basis, making it suitable for projects that need to be adaptable and iteratively developed.

Customers can choose specific roles like UI designers, developers, or QA experts based on their requirements, and a project manager works in close coordination with them to schedule, prioritize, and manage the tasks efficiently.

Key points of this model are:

  • Flexible scope with the option to add changes in each sprint.
  • Agile work culture with frequent two-week sprints that are handled through Jira and communication facilitated through Slack.
  • Daily updates with maximum visibility and ongoing client-TST Technology team collaboration.
  • Feedback and change requests are seamlessly integrated as part of the sprint cycles without disrupting the process.
  • A three-month minimum commitment provides continuity and greater depth of project involvement.
  • Pricing is based on a fixed monthly fee per role involved, offering budget predictability with agility.
  • Deliverables include UI, development, QA, DevOps, deployment, and continuous improvement.

This model works best with clients who desire to build, grow, and continuously refine their products using a responsive and open agile process that encourages close communication and flexibility throughout the lifecycle.

Hourly Support & Iteration Model

The Hourly Support & Iteration model provides an elastic, pay-as-you-go option for clients requiring frequent minor updates, support, or half-time developer support. In contrast to fixed or monthly arrangements, this model enables clients to employ any member of TST Technology's team according to task needs, with project management assistance akin to the monthly engagement model.

Key points of this model are:

  • Full scope flexibility with task-based engagement is ideal for making small, incremental changes.
  • Work is monitored via timesheets and controlled by Jira, promoting openness and responsibility.
  • The customers are given logs and access to the Jira board for immediate monitoring of progress and time consumption.
  • Change requests are simple and processed rapidly on a task-by-task basis without negotiating over hours. 
  • Minimum commitment is a 50-hour block, which is appropriate for startups or companies that need development assistance from time to time.
  • Pricing is on a fixed rate per hour, offering cost control for workload variability.
  • Deliverables include work in any function, such as UI, development, QA, DevOps, and deployment as required.

This model suits clients who need maintenance, light updates, or part-time flexible support without long-term contracts or fixed project scopes.


How to Choose the Right Model?

How to Choose the Right Model

Choosing the right engagement model relies on the project's specific needs, scope, and flexibility preference of the client's project. Take into consideration the following to make the decision:

Select the Fixed Scope Product model if:

  • There is a definite and fixed MVP scope for the project.
  • There will be minimal changes during development.
  • Milestone-based progress and guaranteed pricing are your preference.

Select the Monthly Agile Team Engagement if:

  • You need long-term engagement with frequent scope revisions.
  • Flexibility and adaptability by sprint are crucial.
  • You desire daily reports and active participation in planning.

Choose the Hourly Support & Iteration model if:

  • You require part-time developer assistance or an on-demand service.
  • The scope includes small updates or maintenance work.
  • You prefer to pay for only the hours billed with task-based flexibility.

Recognizing these differences ensures that project goals, budget, and schedule align with the most effective engagement model TST Technology provides.
