ISBSG has data for more than12,500 development projects, new releases and agile sprints. This data can be used to calculate a number of important metrics, including Manpower Delivery Rate (MDR). This is the number of functional size units delivered per person per elapsed month. This short report examines the MDR for different project criteria in the ISBSG Repository.
M&S activities can consume a significant portion (65% – 85%) of a software application’s total cost. Therefore, accurate estimation of M&S effort is crucial for organizations to effectively plan resources and budgets. This report explores how ISBSG data can be used to estimating an application’s M&S effort.
The success of a software development project depends on the accurate estimation of project costs. This short report looks at the importance of cost estimation maturity. It discusses the International Cost Estimating and Analysis Association (ICEAA). This is a non-profit organization that promotes the professional development of cost estimation and analysis skills. We review the cost-estimation educational modules and certification options provided by ICEAA.
This short paper discusses how ISBSG data is used by leading industry experts, including certified Software Cost Estimators, to estimate the cost of software development projects. The paper discusses the difficulties and challenges inherent in software project cost estimation. It also explores how estimation has evolved in Agile contexts. A detailed example demonstrates the steps taken to make a cost estimation for a sample project.
Big Data in software engineering estimation, can be a valuable tool to improve the accuracy, efficiency, and transparency of the estimation process. However, it is important to be aware of the challenges associated with using big data before adopting this approach.
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 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 are a challenging concept. How can NFR data be gathered and used to improve effort/cost estimations.
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.
