The importance of software project estimation

Estimations provide the time, cost, effort and resources required to implement a software project.

Accurate estimations are essential to the success of a project. They ensure that: expectations of project stakeholders are satisfied, project timelines and budgets are met.

Project estimations include contingencies for: scope creep, unexpected events (e.g. Covid-19), employee attrition, overruns in budget and timing.

Understanding the skills and experience of project team members enables more accurate estimations of project schedules.

Historical project data provides useful guidelines for estimations.  It can be used as a benchmark throughout the project’s lifecycle.

Cost Estimation

A trading company would like to replace a large legacy application with an application that offers the same functionality. Senior management understands that an accurate estimate is the basis for a successful project. They intend to carry out an independent cost estimation by a specialized third party. In this case study, the steps that were carried out are listed and the results are given.

Project Estimation

Time and time again, the software industry struggles to come up with accurate estimates for software development projects, releases, or sprints. Lack of understanding of the performance of development teams in combination with low maturity estimation processes, often result in overly optimistic project estimates that are highly probable to result in failing projects and severe cost and schedule overruns.
