Software specification development

Are you starting an IT project without creating a solid specification?
It's like building a house without a plan – you risk exceeding your budget, delays and a final product that doesn't meet your expectations.
At Mits, we turn your ideas and business needs into precise technical guidelines that minimise risk and maximise the efficiency of the entire software development process.

Why is software specification crucial to the success of your project?

Many entrepreneurs and product managers start digital projects with a general vision but without a detailed technical plan. As a result:

  • Initial cost estimates turn out to be either half as much or twice as much as expected
  • Over 70% of IT projects exceed their planned completion time
  • Nearly 60% of software functionality remains unused or is used only occasionally

At Mits, we know that a well-prepared technical specification is the foundation of a successful project – it reduces frustration and saves time and money for all parties involved.

Our software specification development process

We begin by gaining a thorough understanding of your business, users, and goals. We organise workshop sessions during which we:

  • We identify key business problems to be solved
  • We define user personas and their paths
  • We determine measurable project success indicators
  • We analyse existing processes and identify opportunities for optimisation

As in the case of the project for OneMillion, where our discovery workshops allowed us to identify the key functionalities that will most accelerate the adoption of cryptocurrencies by users, which focused the entire specification on the most valuable elements.

We transform the collected information into specific functional and non-functional requirements:

  • We create a comprehensive list of functionalities prioritised according to the MoSCoW method (Must have, Should have, Could have, Won't have).
  • We define requirements for performance, scalability and security.
  • We identify technical dependencies and integrations with external systems.
  • We develop business process maps and data flow diagrams.

An example is our project for KNF, where we created a detailed functionality map taking into account complex accessibility requirements for visually impaired people (WCAG) and the high security standards required by a financial institution.

We develop a conceptual system architecture that will serve as the foundation for development:

  • We select optimal technologies and frameworks tailored to the specifics of the project
  • We design the database structure and relationship schema
  • We create a system architecture diagram with scalability in mind
  • We define a data security and protection strategy

In the project QualUp our system architecture specification included a complex mechanism for mapping survey responses to recommendations, which required precise design of the database structure and processing algorithms.

We visualise key elements of the user interface:

  • We create functional mock-ups of main screens and user flows.
  • We design interactive prototypes of key functionalities.
  • We define visual styles and interface components.
  • We test usability with potential users.

As in the case of our collaboration with the Irish agency Madbit, where our UX mock-ups for the MyWheels.ie project allowed us to test the intuitiveness of the interface before embarking on a costly development process.

We finalise the specification in the form of comprehensive documentation:

  • Detailed functional and technical specification document
  • User stories and acceptance criteria for the development team
  • Development schedule divided into iterations (sprints)
  • Time and cost estimates divided into stages
  • Test plan and implementation strategy

As with applications Labilab, where our comprehensive documentation enabled smooth collaboration between several development teams and delivery MVP a complex e-commerce system in just 3 months.

Benefits of professional software specification Mits

Reduction in development costs by up to 30%

Precise specifications eliminate costly changes during development. Our clients save an average of 30% of their project budget by minimising redesigns and changes to already implemented functionalities.

Predictable schedule with 85% accuracy

Our specifications contain detailed time estimates that allow us to forecast project milestone dates with a high degree of accuracy. Our clients can plan their marketing and business activities in advance, confident that deadlines will be met. In the project for KNF our specifications allowed us to plan the implementation with weekly precision, which was crucial for coordination with other activities of the institution.

Eliminating misunderstandings between business and IT

Our specification provides a common language between business stakeholders and the technical team. We document requirements in a way that is understandable to both non-technical people and developers, eliminating costly misunderstandings.

Flexibility in changing market conditions

We create specifications with potential changes in mind. Our documents take into account modular architecture and expandability, allowing the design to be adapted to changing requirements without the need for a complete redesign.

Securing your business by clearly defining areas of responsibility

The specification constitutes a clear and unambiguous agreement between the contracting authority and the contractor. Precise definition of the scope of work, expected results and acceptance criteria minimises the risk of disputes and misunderstandings.

A foundation for product development for years to come

The specifications we create are not just documents for the development phase – they are the foundations of a long-term product strategy.We take into account future development directions, potential integrations and scaling, giving you the confidence that your software with our solutions will keep pace with the growth of your business.

Success story: How precise specifications saved a project worth PLN 1.2 million

One of our fintech clients approached us after an unsuccessful collaboration with another development company. The previous contractor began work based on a general brief, without detailed specifications, which led to:

  • Budget overruns of 40% with only 60% functionality implemented
  • Inconsistent system architecture causing performance issues
  • Lack of documentation preventing effective project takeover

Our team:

  • Conducted a comprehensive audit of the existing code and functionality
  • Created a detailed specification of missing elements with an accurate cost estimate
  • Developed a plan to refactor the existing code, minimising the risk of downtime

Results:

  • Completion of the project within 7 months, in accordance with the new specification
  • Savings of over PLN 400,000 thanks to precise work planning
  • Implementation of a system with 99.98% availability, in accordance with business requirements
  • Increase in user satisfaction by 67% thanks to improved usability

Frequently asked questions about creating software specifications

The time depends on the complexity of the project, but usually the process takes between 2 and 6 weeks. For smaller projects (e.g. a mobile application with limited functionality), we can deliver the specification in 2 weeks. More complex systems (e.g. an e-commerce platform with multiple integrations) require 4-6 weeks for thorough analysis and documentation. At the beginning of the cooperation, we always present a detailed schedule of work on the specification.

The cost of specifications usually accounts for 5-10% of the total project budget, which is an investment that pays off in the form of savings in later stages. For example, specifications for a mobile application of average complexity cost around PLN 10,000-20,000, while for a complex business system they can cost PLN 30,000-50,000. Remember that every pound invested in good specifications saves an average of PLN 5-10 at the implementation stage.

No, that's exactly what we're here for! Many of our clients come to us with only a general idea or business problem to solve. Our discovery process helps transform these initial concepts into concrete, actionable requirements. We have worked with clients who had only a general business concept and ended up with a complete specification ready for implementation.

Absolutely not. We would be honoured if you chose us for further cooperation, but the decision is entirely yours. We deliver the specification as a standalone product that you can use in cooperation with any development team. Our specification is created in accordance with industry standards, making it understandable to any professional development team. 

Our specifications are created with the future in mind. We design modular architecture that allows for flexible expansion of functionality. In addition, each specification includes a ‘Future Considerations’ section that describes potential directions for development and recommendations for future functionalities. We also create infrastructure scalability guidelines to protect your product from sudden increases in user numbers.

The standard specification package includes: a business requirements document (BRD), a functional specification with a description of all features and use cases, technical documentation with system architecture and technology selection, UX/UI mock-ups of key screens, time and cost estimates, and an implementation plan. We deliver all documents in editable formats (Docx, Figma) so that you can easily make changes and share them with your teams.

Each specification undergoes a multi-stage verification process. First, it is reviewed by an independent system architect, then verified for business completeness with an analyst, and finally validated by the UX team for user experience consistency. Additionally, we submit the specification for formal client approval, conducting detailed reviews of each section to ensure that all requirements have been correctly understood and documented.

Ready to eliminate uncertainty in your IT project?

Good specifications are an investment that pays for itself many times over throughout the product's life cycle. Do not risk your budget, deadlines, and the success of your project by starting without a solid plan.

Do not delay your decision! We currently have limited availability for new specification projects – we accept new projects on a first-come, first-served basis each month to ensure the highest quality and individual approach.
