Software cost estimation

The paper gives an overview of the state of the art of software cost estimation (SCE). The main questions to be answered in the paper are: (1) What are the reasons for overruns of budgets and planned durations? (2) What are the prerequisites for estimating? (3) How can software development effort be estimated? (4) What can software project management expect from SCE models, how accurate are estimations which are made using these kind of models, and what are the pros and cons of cost estimation models

Estimating the Costs of Foundational Public Health Capabilities: A Recommended Methodology

The Institute of Medicine’s 2012 report on public health financing recommended the convening of expert panels to identify the components and costs of a “minimum package of public health services” that should be available in every U.S. community. The report recommended that this minimum package include a core set of public health programs that target specific, high-priority preventable health problems and risks, along with a set of “foundational public health capabilities” that are deemed necessary to support the successful implementation of public health programs and policies. In response to this recommendation, the Robert Wood Johnson Foundation, in collaboration with the US Centers for Disease Control and Prevention and other national professional associations, formed the Public Health Leadership Forum, an expert consensus panel process to identify a recommended set of core programs and foundational capabilities for the nation. The Forum’s initial charge focused on the specification of foundational public health capabilities. The Foundational Capabilities Workgroup was formed as a part of the Forum to identify and define the elements to be included as foundational capabilities for governmental public health agencies at both state and local levels. The Robert Wood Johnson Foundation asked the National Coordinating Center for Public Health Services and Systems Research based at the University of Kentucky to convene a second expert panel workgroup, the Workgroup on Public Health Cost Estimation, to develop a methodology for estimating the resources required to develop and maintain foundational capabilities by governmental public health agencies at both state and local levels. Working in parallel with the Foundational Capabilities Workgroup, this Cost Estimation Workgroup has considered relevant cost-accounting models and cost estimation methodologies, and reviewed related cost estimation studies, in order to make recommendations on an approach for generating first-generation estimates of the costs associated with developing and maintaining foundational capabilities

A systematic review of software development cost estimation studies

This paper aims to provide a basis for the improvement of software estimation research through a systematic review of previous work. The review 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. A web-based library of these cost estimation papers is provided to ease the identification of relevant estimation research results. The review results combined with other knowledge provide support for recommendations for future software cost estimation research, including: 1) Increase the breadth of the search for relevant studies, 2) Search manually for relevant papers within a carefully selected set of journals when completeness is essential, 3) Conduct more studies on estimation methods commonly used by the software industry, and, 4) Increase the awareness of how properties of the data sets impact the results when evaluating estimation methods

Optimal Cover Prices and the Effects of Website Provision on Advertising and Magazine Demand

I derive and estimate a model for cover price setting in print media markets where actors are faced by two interrelated demand curves: the demand for the print medium and the demand for advertising space. Publicly available data on German women?s magazines observed between 1998 and 2001 are used in the GMM estimation. Main findings are that my estimated marginals cost coincide well with those of industry sources, magazines with a high circulation elasticity of advertising demand price markedly below marginal cost and website provision neither has a significant effect on magazine nor on advertising demand.
