Developing Effective Software Estimation Techniques

Course: 930   Type: RealityPlus   Duration: 3 Days
Quick Enrol  

You Will Learn How To

  • Prepare a software project estimate through an iterative process
  • Develop an initial estimate using the expert judgement method
  • Apply historical data for greater precision in an estimate
  • Refine the size or scope estimate using a component-based method
  • Perform calculations to determine the magnitude of a project
  • Translate a size or scope estimate into a time, schedule and cost estimate

Course Benefits
Effective software development estimates reduce the risks of increased development costs, late delivery, and missed features and functionality. Throughout this course, you develop your estimation skills, implement new processes and use proven techniques to estimate software projects. You learn to estimate the size, cost, effort and schedule of a project, and improve estimate accuracy.

Who Should Attend
Software development professionals who need to create estimates or establish an estimation process in their organisation.

RealityPlus
A media-rich business simulation immerses you in a challenging and realistic software development environment. Experiential and PC-based activities include:
  • Generating questions that clarify the scope of the project
  • Interviewing consulting experts using video simulation
  • Producing an estimate based on expert judgement
  • Gathering historical data from a meeting with the manager of a previous, similar project
  • Improving your estimate based on historical data
  • Analysing the work breakdown structure
  • Interviewing virtual team members to gather estimates for specific activities using single-point and PERT techniques
  • Estimating the effort and producing a schedule, time and cost estimate
  • Leading a management briefing to present your results
