Many custom software development projects start with a clear goal: a company wants to improve an internal process, a business wants to launch a new digital product or a team wants to replace spreadsheets and manual internal work with a more efficient system.
The next step usually is finding a software development company, share the requirements, receive a quotation, and get development started. Unfortunately, this is also where a number of projects begin to run into problems.
The initial requirements that seemed clear at the start turned out to be incomplete. New workflows were introduced during development. Different stakeholders have different expectations of how the system should work. Timelines start to slip as decisions that should have been made earlier are only made halfway through the project.
Over the years, we've seen this happen in projects of all sizes. A client may approach us to build a mobile app, only for us to discover during planning that their users actually spend more time at a desk and their app would serve them better if it was a web application. Sometimes a feature/requirement sounds simple at first, but later turn out to involve multiple approval flows, business rules, or edge cases once we start asking more questions.
In many cases, the issue here isn't the technology being used, or the capability of the development team. The real problem is that the project moved into development too early - before there was a complete understanding of what actually needed to be built and why.
This is where a structured software discovery phase comes in.
A project discovery phase helps businesses clearly understand their objectives, define their workflows and identify requirements before development begins. It creates a source of truth for informed decisions, more accurate estimates, and a much better chance of project success.
In this blog, we'll explore what a software discovery phase is, what happens during discovery, and why it is very often one of the most important stages of any custom software, web application, or mobile app development project.
What Is a Software Discovery Phase (Definition)
A software discovery phase is the process of understanding the problem before deciding on the solution.
While many think of software projects as coding or development, the reality is that the most important decisions are made long before the developers write a single line of code. A discovery phase usually focuses on these questions:
- What problem are we trying to solve?
- Who will be using this system?
- What are the current workflows? How are things currently being done?
- What are the risks that need to be considered?
- What are the most important features to be included in the system?
It's like drawing up a blueprint before constructing a building. No architect would start construction without first understanding the purpose of the building, who will be using it, how people will move through it, and what constraints need to be considered. The same thing applies here in software development.
One thing we've learned from working on software projects with our clients is that business knowledge can be difficult to transfer. Business stakeholders often have many years of experience and understanding of their operations. They know why certain workflows need to be there, why certain processes exist, which problems would occur most frequently, and what frustrations their team face every day. Because this knowledge has become second nature over time, it isn't always easy to communicate these details to the development team.
Developers, on the other hand, often think in terms of systems behavior, workflows, and implementation. When information isn't detailed enough, it's natural for developers to assume requirements to sort of fill in the blanks on their own on what seems intuitive or logical. These assumptions can often be reasonable, but they may not reflect how the business actually operates.
For example, a client might tell us: "We need managers to approve leave requests". That sounds straightforward, but once discussions start, additional details that needed to be ironed out may be:
- What happens if the manager is on leave?
- How many levels of approvals are there? Do certain employees need multiple approvals?
- Should employees receive a notification when their leave status changes?
- Can a manager revoke an approval after it has been approved?
- What are the public holidays that you observe?
The answers to these questions can significantly influence the design of the solution. These details are often obvious to the people who work with this process every day. But they may not be apparent to the development team unless discussed and documented upfront.
That's why a project discovery phase is less about documenting features and more about alignment and shared understanding. By the end of this process, business stakeholders, designers, developers and project managers should all have a clear and consistent view of the problem being solved, the proposed solution, and what success looks like for the project.
What Happens During A Discovery Phase?
Every project is different, but most discovery phases follow a similar objective - turning a business problem into a clear and actionable plan for development. A discovery phase typically involves understanding the business, defining the requirements, identifying risks, and validating proposed solutions before development begins.
Understanding the Business Problem
Many software projects start with a proposed solution. Clients may want a mobile app, or a department may want a new system, or a stakeholder may want to automate a specific process. But before discussing the requirements, it's important to first understand the underlying problem.
Are we trying to reduce manual work? Improve visibility across departments? Eliminate duplicate data entries? Improve operational efficiency? Understanding this objective provides the foundation for every decision that follows. It helps prioritize features, evaluate trade-offs, and ensure that the final solution actually delivers meaningful value to the client.
Mapping Current Workflows
Once the problem is understood, the next step is to understand how the business currently operates. This often includes documenting existing workflows, approval processes, data flows, the departments that are involved and common issues/pain points.
Another thing we've learned is that people often perform tasks differently from how they describe them on paper. A process that appears straightforward may involve several manual workarounds or approval processes that have developed over time. By mapping these out early, the team gains clearer understanding of what needs to be supported by the new system.
Defining Requirements & Key Deliverables
Now that the business and its workflows are understood, the next step is translating those discussions into something visual. Depending on the complexity of the project, this may include flowcharts, wireframes, technical specification documents (TSDs), data models, or other supporting documentation.
Our personal favourites are flowcharts and wireframes. Flowcharts help map how users move through a process, how decisions are made, and how the different parts of the system interact with one another. They provide a high-level view of the workflows that the system needs to support so there's alignment between the business and the development team.
Wireframes build on these workflows by visualising how users will interact with the system. They show the screens, buttons, actions, and user journeys without focusing on colours, branding or visual design.
The biggest advantages of flowcharts and wireframes is that they allow stakeholders to very quickly validate ideas before development begins. It's much easier to identify missing steps, edge cases or misunderstandings when reviewing a visual workflow than when discussing them verbally. Stakeholders can ensure the system reflects how the business actually operates.
This helps reduce misunderstandings and allows development to proceed with shared alignment.
Identifying Risks and Technical Constraints
Finally, potential risks need to be flagged before they become costly surprises. These may include third party integrations, legacy systems, data migration requirements, security or regulatory requirements or performance considerations. Once these factors are identified early, the development team can make informed decisions and plan accordingly.
By the end of the discovery phase, the goal is to create enough clarity and alignment that development can begin in confidence.
The Benefits of a Project Discovery Phase
One question we sometimes get is: "Can't we figure out these details during development?"
Some details do naturally evolve as a project progresses, but the reality is that changes become significantly more expensive once development has already begun. Imagine this: halfway through development, it was discovered that a workflow requires 3 levels of approval instead of one. Or two departments have completely different expectations of how a feature should work.
At that stage, development on related modules may have been completed. Those work may need to be revisited, screens may need to redesigned, testing has to be performed again, and timelines will need to be adjusted.
A discovery phase reduces this uncertainty by encouraging stakeholders and the development team to ask those questions before development begins - leading to more accurate estimates, fewer surprises during development and a much smoother overall project experience. More importantly, it ensures that the team is building the right solution rather than just building a solution.
How Long Does a Discovery Phase Take?
The answer to this question depends on the complexity of the project. A relatively simple internal tool with a small number of users and clearly defined workflows may only require a week or two of discovery. A larger system involving multiple departments, third-party integrations, approval workflows or complex business rules may require several weeks or months of planning and validation.
It's important to remember that the purpose of the discovery phase is not to produce as much documentation as possible. Its objective is to spend enough time to understand the problem, validate assumptions, and have shared alignment with all stakeholders before development begins.
In our experience, there is usually a point where additional planning provides diminishing returns. The goal is not to solve every single uncertainty, but to create enough clarity that the project can move forward.
When Does Discovery Happen?
In our experience, every software project involves discovery in some form. The difference is only the depth and structure of the process.
For simpler projects with clearly defined requirements, discovery is often included as part of the development project itself. Initial discussions are held with stakeholders, workflows are reviewed together, and wireframes or designs are created at the beginning of the project before development begins.
In these situations, the project scope is clear enough that a development quotation can be prepared upfront, with discovery activities taking place during the early stages of the development engagement.
For larger or more complex projects, the situation may be different. Sometimes, even when the business problem is understood, but the exact solution is still being explored. There may be multiple stakeholder groups involved, existing workflows that need to be analyzed and optimized, new third-party integrations that need to be assessed, or requirements that are not yet fully defined.
In these cases, it can be difficult to accurately estimate the development effort before discovery has been completed. Development teams may need to make assumptions in order to prepare a quotation. If these assumptions turn out to be incorrect later, it can lead to changes in timelines, budget, or project scope.
We would recommend a dedicated discovery phase to be conducted first. The output of this phase will typically include flowcharts, wireframes, technical specifications, or other documentation required to clearly define the project scope. Once this is done, the development project can be estimated with much better accuracy.
Neither approach is better than the other. The more suitable approach depends on the complexity of the project, clarity of the initial requirements and the level of uncertainty involved. What remains consistent is the objective - to create enough shared alignment, reduce uncertainty and provide a clear foundation for the development project to move forward.
Conclusion
Successful custom software development projects rarely begin with development. They always begin with understanding - understanding of the business problem, the people that will be using the system, the workflows, constraints and the objectives that the software needs to support.
At Double Dot, we've found that the most successful projects are not necessarily the ones with the largest budgets or the most advanced tech. They are the projects where stakeholders and the development team share a very clear understanding of the problem, the requirements and desired outcome from the very beginning.
That's what a discovery phase is - it's to ensure the right solution is built for the right problem.
