The project needs a clear vision from the beginning because you need to know what you want to develop and why you need it. Vision alone is not sufficient to actually kick-start the development process – you must detail it, make it more transparent, and break it down into more traceable and manageable requirements.
With vague or non-existent specifications, you leave your product exposed to the following risks:
The inability to begin working on a product at all;
Inconsistencies, bugs, and issues resulting from employees interpreting vague requirements in their own ways;
Estimation problems;
Inadequate prioritization of project deliverables;
Spending extra time and money on reworks;
Team morale is at an all-time low;
Despite the excellent technical quality, an app’s functionality does not satisfy the end users’ needs.
You can’t get where you’re going without requirements. They set the project in motion and point it in the right direction – the one you have initially envisioned. However, it does not mean that your specifications will stay the same throughout the entire development process. They might slightly change to keep up with stakeholders’ and users’ dynamic needs.
A great deal of the planning will depend on your initial requirements. Even so, sometimes the market situation changes, or you will need more work to handle growing traffic, so you might need to refine them. With the help of your business analyst and project manager, this process will go on smoothly.
Issues with requirements refinement and prioritization as the project progresses may also cause obstacles. As per the State of Software Development 2021 report, specifications prioritization is 4th among the top five reasons for delivery problems in software development teams. The same report lists unclear deliverables, unrealistic expectations, and inaccurate estimations as the other top 3 reasons for failures. Of course, they also trace back to inadequate requirements. So you should not disregard the necessity of eliciting and refining them. For help, you can hire business analysts or ask your outsourcing vendor – each of them has experience with this type of job.
But how do you determine if specs are good enough to start and drive your project?
