Software Cost Estimation

/in

Software development projects often fail to meet expectations, exceed budgets, and overrun schedules. Often, the cause is bad estimation practices.
Nesma and the International Cost Estimation and Analysis Association (ICEAA) developed the Cost Estimation Body of Knowledge for Software (CEBoK-S).
This presentation addresses the industry’s main issues, CEBoK-S and aims to solve these issues. ISBSG data is used to estimate software projects using functional size and relevant historic data.

Prioritizing Requirements

/in

We present the methods that focus solutions to the “Next Release Problem” for agile-driven developments. This includes: new algorithm proposals and novel techniques that model how the software requirements interact .

Non-Functional Requirements

/in

Non-Functional Requirements are a challenging concept. How can NFR data be gathered and used to improve effort/cost estimations.

Estimating Software Costs

/in

The presentation describes capabilities and capability-based planning. Discussed are the challenges in software cost estimation and how capability-based cost estimation models for software differ throughout the life cycle. I conclude with a summary methodology to develop a capability-based cost estimation for software, which is to define capability groups with similar software functions and associated effort ranges.

Agile Metrics and the Impact of Team Size

/in

A study of agile projects in the ISBSG dataset that included metrics such as the number of sprints/iterations and sprint/iteration length was done. This resulted in a normalized velocity metric (FPs Per Sprint Week/Person) that could be used to for benchmarking purposes. This metric, along with team size could be used to examine the productivity changes with different team sizes.

Monitoring Agile Development

/in

Create new functionality, enhance existing functionality, remove technical debt, compensate respective effort in a controlled, measurable way.

Analysis of Project Size per Year

/in

This short paper examines whether there have been more New Development or Enhancement type projects submitted to the ISBSG Repository. It investigates whether the median project size for these projects has increased or decreased over time.

Benchmark Report

/in

How would you like to have your project’s productivity benchmarked against the ISBSG Repository? This short paper explains how you can receive a free benchmark report, when you submit project data to the ISBSG repository.
