Concept of Operation

19 September 2023/in estimation

Estimating the cost and schedule of custom software development from preliminary requirements or a Concept of Operations (ConOps) document can be challenging. Software size and productivity are major drivers of software development costs. This presentation outlines a streamlined six-step process to develop a data-founded and defensible cost and schedule ROM estimate from high-level requirements/ConOps documents. A sample ConOps case study will be used to demonstrate the six-step process.

Software Cost Estimation

19 September 2023/in estimation

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.

Non-Functional Requirements

19 September 2023/in estimation

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

Estimating Software Costs

19 September 2023/in estimation

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.

Analysis of Practical Software Project Estimation

Learn how Project Delivery Rate can be estimated using software and team sizes, using the ISBSG book, “Practical Software Project Estimation”.

Practical Applications of ISBSG Data

29 March 2023/in estimation

Harold Van Heeringen has extensively used ISBSG Data as a benchmarking tool for client organizations.
In this webinar, Harold uses his expertise to demonstrate how ISBSG data (in Excel-format and via the ISBSG Productivity Data Query Tool) can be used to improve estimation and planning.

Re-evaluation of Estimation Study Results using ISBSG Data

27 February 2023/in estimation

This webinar evaluates any differences between replications of research studies that used ISBSG data, to estimate software-effort.

Software Cost Estimation

IT project data enables organizations to generate consistent and statistically significant estimation models.

Cost Estimation

23 January 2022/in 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.
