A technical feasibility check is a focused analysis in which you examine whether a software idea or project is technically achievable within the available time, budget, and existing infrastructure. It gives you a clear picture of what is possible before you invest in actual development. This article answers the most frequently asked questions about what such a check entails, how it works, and what you can do with it.
When do you need a technical feasibility check?
You need a technical feasibility check when you are considering a new software project but are not yet sure whether your idea is technically achievable. This is especially true when the project is complex, depends on existing systems, or when your budget and timeline are tight. A check prevents you from discovering halfway through development that something does not work.
Concrete situations in which such an analysis is useful:
- You want to build a new digital product and do not know which technologies are the best fit
- Your existing software needs to be extended or connected to other systems
- You are considering a switch to a new platform or a different technical architecture
- Investors or stakeholders require substantiation before releasing budget
- You are working with a strict deadline and want to know what is realistically achievable
The earlier you conduct a feasibility check in the process, the more value you get from it. At the start of a project you can still adjust course without major costs. Later in the process, that becomes considerably more difficult.
What exactly is examined during a feasibility check?
During a technical feasibility check you examine whether the desired functionality can be technically built, which technologies are required for this, what risks exist, and whether the necessary expertise is available. It is not about a complete elaboration of the system, but about a well-founded assessment of the technical reality.
Typical components of such an analysis are:
- Technology selection: Which programming languages, frameworks, and platforms are most suitable?
- Integrations: Can existing systems, APIs, or databases be connected?
- Scalability: Can the system grow along with usage?
- Security: Are there specific security requirements and how are they addressed?
- Technical risks: Where are the vulnerable points in the architecture or approach?
- Team requirements: What expertise is needed and is it available?
The result is not a definitive design, but a clear overview of what is technically possible, where the challenges lie, and what choices you need to make before you start building.
What is the difference between a technical feasibility check and a project estimate?
A technical feasibility check answers the question of whether something can be built. A project estimate answers the question of how much time and money it costs to build it. Both are useful, but they serve a different purpose and belong at a different point in the process.
The distinction is important to understand:
- Feasibility check: Focused on technical possibilities, risks, and architecture choices. Often shorter and less detailed. Answers the question: can this be done?
- Project estimate: Focused on timelines, budgets, and task allocation. Requires a more clearly defined scope. Answers the question: what does this cost?
In practice, these two analyses often go hand in hand. A feasibility check provides the technical insights needed to produce a reliable project estimate. Without that foundation, an estimate is little more than a guess.
How long does a technical feasibility check take?
A technical feasibility check takes on average between two and ten working days, depending on the complexity of the project, the availability of documentation, and the level of depth required. Simple projects can be assessed quickly; complex systems with many integrations require more time.
Factors that influence the turnaround time:
- The scope and complexity of the desired functionality
- The amount of existing technical documentation that is available
- The number of systems and integrations involved
- The extent to which stakeholders are available for consultation
A good feasibility check is not a superficial scan, but neither is it an extensive design. It is a focused analysis that is fast enough to be actionable, yet thorough enough to draw reliable conclusions.
What are the possible outcomes of a feasibility check?
The outcomes of a technical feasibility check typically fall into three categories: the project is technically feasible as described, it is feasible provided certain adjustments are made, or it is not feasible in its current form. Each of these outcomes gives you valuable information to make a well-considered decision.
Feasible as described
Your idea can be built with the available technologies and within a realistic timeframe. The check confirms your approach and gives you the technical substantiation to move on to the next phase.
Feasible with adjustments
The idea is technically achievable, but changes are required. Think of choosing a different technology, adjusting the scope, or redesigning part of the architecture. This is the most common outcome and often leads to a stronger end product.
Not feasible in its current form
The stated requirements are technically not achievable within the given constraints. This may sound like bad news, but it is valuable: you prevent a major investment in something that does not work and can adjust course in time or choose an alternative approach.
Who conducts a technical feasibility check?
A technical feasibility check is carried out by an experienced software architect, a senior developer, or a technical advisor with broad knowledge of systems, architectures, and programming languages. It is important that the person conducting the check has no stake in a particular outcome, so that the assessment remains objective.
In practice, there are three options:
- Internal technical talent: If you have your own CTO or senior developer, they can carry out the check. The downside is that they may be too close to the project for an objective perspective.
- An independent consultancy: Offers objectivity, but can be more expensive and less agile.
- A software development partner: Combines technical depth with practical experience in building similar systems. This is often the most efficient choice, especially if you also want to outsource the development afterward.
Always choose someone with demonstrable experience in software development and knowledge of the technologies relevant to your project.
