Estimation

Software estimation at SLANG is the process of predicting the most realistic amount of effort required to develop or maintain software based on incomplete, uncertain and noisy input. Building software is not the same as building a bridge or road because of the inherent variability of functional requirements before and during software development. Software cost estimation in software engineering provides a reliable predictive method to understand future development activity.

While techniques such as Agile or Scrum are designed to mitigate this variability at the team level, program or software project estimation for planning or budgeting needs remain for the enterprise. Inaccurate software program or project estimates are the cause of a lot of waste and increased project risk.
