This paper summarizes estimation knowledge through a review of surveys on software effort estimation. Main findings were that: (1) most projects (60-80%) encounter effort and/or schedule overruns. The overruns, however, seem to be lower than the overruns reported by some consultancy companies. For example, Standish Group's "Chaos Report" describes an average cost overrun of 89%, which is much higher than the average overruns found in other surveys, i.e. 3040%. (2) The estimation methods in most…

A Current Assessment of Software Development Effort Estimation
TLDR
The results show that this assumption that inaccurate estimates are the main reason for software development effort estimation is not reasonable in many cases and research needs to find new measures to assess the actual estimation accuracy.
Accounting testing in software cost estimation: A case study of the current practice and impacts
TLDR
Assessment of the current practice of estimating testing activities, and the impact of these practices on estimation and project success shows that companies easily deviate from their standard procedures, when estimating testing.
A survey on software estimation in the Norwegian industry
TLDR
An in-depth survey of software companies' estimation methods suggests that expert estimation is the dominating estimation method, that estimation accuracy is not much impacted by use of formal estimation models, and that software managers tend to believe that the estimation accuracy of their company is better than it actually is.
The clients' impact on effort estimation accuracy in software development projects
This paper focuses on the clients' impact on estimation accuracy in software development projects. Client related factors contributing to effort overruns as well as factors preventing overruns are

TLDR
The results clearly show that, in the context of the organization studied, cost estimation based on unstructured expert judgment is unreliable.
A Systematic Review of Software Development Cost Estimation Studies
TLDR
A systematic review of previous work identifies 304 software cost estimation papers in 76 journals and classifies the papers according to research topic, estimation approach, research approach, study context and data set to provide a basis for the improvement of software-estimation research.

Software Development Effort Estimation - Demystifying and Improving Expert Estimation
The main determinant of many types of software-related investments is the amount of development effort required. The ability of software clients to make investment decisions based on cost estimates
Requirements Effort Estimation: The State of the Practice
TLDR
The results of an exploratory survey concerning the state of practice of requirements engineering are reported with an emphasis on linking the reported practices to productivity of the development process and the project’s duration and budget.

TLDR
A survey conducted at the Jet Propulsion Laboratory (JPL) found that the majority of the technical staff estimating software costs use informal analogy and high-level partitioning of requirements, and that no formal procedure exists for incorporating risk and uncertainty.
Causes of inaccurate software development cost estimates
Information systems software cost estimating: a current assessment
TLDR
A study of information systems managers and other information systems professionals confirmed that information systems software cost estimating is an important concern and the use of the estimator as system developer, the careful monitoring of systems development projects, and the inclusion in performance evaluations of success in meeting estimates were associated with more accurate cost estimating.

Could large UK corporations and computing companies use software cost estimating tools? – a survey
TLDR
A survey of large UK corporations and computing companies was targeted, since it was found that while almost all saw estimation as a problem and used some form of project planning tool, fewer than a third used any form of estimating tool.
