Problem sizing is a crucial aspect of project management, often overlooked in favour of more glamorous aspects such as ideation and execution. Understanding the problem size can significantly impact the success of a project. It aids in determining the resources required, the time needed, and the potential risks involved.
A common mistake is to equate problem size with solution size. The two are distinct. The problem size refers to the extent of the issue faced by the user or business, while the solution size is the scale of the effort needed to resolve the problem.
There are three primary ways to size a problem. Firstly, by the number of people affected – the more individuals a problem impacts, the larger it is. Secondly, by the frequency of occurrence – problems that occur often are bigger than sporadic issues. Lastly, by the impact – problems that cause significant disruption are larger than those causing minor inconveniences.
Problem sizing is not a one-off task. It should be revisited throughout the project lifecycle as it can change over time. Regular reassessment ensures that the project remains aligned with the problem it aims to solve.
In conclusion, effective problem sizing can lead to better project outcomes. It helps in resource allocation, risk assessment, and maintaining project relevance. It is a vital but often ignored aspect of project management.
