When a company needs to build a digital product or strengthen its existing IT processes, it has to choose the right engagement model. Two approaches dominate the IT services market: turnkey software development (Project Outsourcing) and IT staff augmentation. Choosing the wrong model can lead to wasted budgets, delayed timelines, or a product that is difficult to maintain.

When a company needs to build a digital product or strengthen its existing IT processes, it has to choose the right engagement model. Two approaches dominate the IT services market: turnkey software development (Project Outsourcing) and IT staff augmentation.

Choosing the wrong model can lead to wasted budgets, missed deadlines, or a product that becomes difficult to maintain. Solway breaks down the advantages, disadvantages, and financial specifics of both approaches to help you choose the model that best fits your business needs.

What Is Turnkey Software Development (Project Outsourcing)?

Turnkey software development means outsourcing an entire project, or a specific project stage, to an IT vendor that takes full responsibility for its delivery.

You come to us with a business idea or an existing specification, and the Solway team takes care of the entire development lifecycle: business analysis, design, architecture, development, testing, and release.

You primarily communicate with a Project Manager and review completed milestones and deliverables.

Advantages:

  • Minimal management effort: you do not need to manage developers directly or get involved in technical details.
  • Clear responsibility: the vendor is responsible for delivery quality, deadlines, and technical implementation.
  • Ready-to-go team: a complete team can be assembled for the project, including analysts, designers, frontend and backend developers, and QA engineers.

Disadvantages:

  • Higher requirements for project specifications. Significant changes to the scope during development may require additional agreements and increase the overall budget.

What Is IT Staff Augmentation?

Staff augmentation is a model where individual IT specialists — developers, QA engineers, analysts, and other professionals — temporarily join and strengthen your existing team.

Solway specialists work under your operational management. They integrate into your internal processes, communicate through your corporate tools such as Slack or Microsoft Teams, and receive tasks directly from your CTO, Team Lead, or Product Owner.

Advantages:

  • Fast access to talent: the right specialist, such as a Senior React or Middle Node.js developer, can join the project within a few days.
  • Flexible budgeting: you pay for the specialist’s actual working time under a Time & Material model. When the workload decreases, you can scale the team down without going through a lengthy hiring or termination process.
  • Full control: your team manages priorities, tasks, and development processes directly.

Disadvantages:

  • You need sufficient technical expertise in-house — for example, a CTO, Team Lead, or experienced Project Manager — to assign tasks and manage the work effectively.

Which Model Is Right for You?

To choose the right approach, consider several key questions about your project.

Choose turnkey development if:

  • You do not have an internal IT department or a full-time CTO.
  • You need to build a product from scratch, such as an MVP, corporate portal, CRM system, or mobile application.
  • You understand your business requirements but are unsure which technology stack should be used.
  • You want to define the expected project budget, scope, and delivery timeline in advance.

Choose IT Staff Augmentation if:

  • You already have an internal IT team, but it lacks capacity or is struggling to meet release deadlines.
  • You urgently need expertise that is not available in-house, such as an AI engineer or a specialist in a specific technology.
  • Your product is continuously evolving, requirements change frequently, and a fixed specification is impractical.
  • You need to temporarily replace a key team member or quickly increase development capacity without interrupting the project.

Comparing the Two Models

Turnkey Development (Outsourcing)
Process management: handled by the Project Manager on the vendor’s side.
Payment model: you pay for a completed product, milestone, or agreed scope.
Required internal expertise: mainly an understanding of your business requirements.
Typical time to start: 2–4 weeks for discovery, estimation, and planning.

IT Staff Augmentation
Process management: handled by your CTO or Team Lead.
Payment model: you pay for the specialist’s actual working hours under a Time & Material model.
Required internal expertise: strong in-house technical expertise is needed.
Typical time to start: 2–3 days for interviews and onboarding.

Solway’s Hybrid Approach

In practice, businesses often need more flexibility. Solway also works with hybrid engagement models for larger and more complex projects.

For example, we can develop the first version of your system as a turnkey MVP, taking responsibility for the technical delivery and launch.

Once the product is successfully launched and your internal IT team grows, we can gradually transfer the source code and project knowledge while continuing to strengthen your team with Solway specialists for long-term development, support, and scaling.
