  • ICSE - Software engineering Economics: background, current practices, and future directions
    Proceedings of the 24th international conference on Software engineering - ICSE '02, 2002
    Co-Authors: Hakan Erdogmus, D.j. Reifer, Warren Harrison, Barry Boehm, Kevin Sullivan
    Abstract:

    The field of Software Economics seeks to develop technical theories, guidelines, and practices of Software development based on sound, established, and emerging models of value and value-creation---adapted to the domain of Software development as necessary. The premise of the field is that Software development is an ongoing investment activity---in which developers and managers continually make investment decisions requiring the expenditure of valuable resources, such as time, talent, and money. The overriding aim of this activity is to maximize the value added subject to an equitable distribution among the participating stakeholders. The goal of the tutorial is to expose the audience to this line of thinking and introduce the tools pertinent to its pursuit. The tutorial is designed to be self-contained and will cover concepts from introductory to advanced. Both practitioners and researchers with an interest in the impact of value considerations in Software decision-making will benefit from attending it.This tutorial is offered in conjunction with the Fourth International Workshop on Economics-Driven Software Engineering Research (EDSER-4). The tutorial is meant in part to enable those who would like to participate in the workshop, but who might not possess the requisite background, to come up to speed.

  • the 2nd international workshop on Economics driven Software engineering research workshop session
    International Conference on Software Engineering, 2000
    Co-Authors: Kevin Sullivan
    Abstract:

    The need for research in this area is indicated by the serious shortfalls in our understanding of how best to design Software for value creation. There are at least two basic dimensions to this shortfall. First, the core competency of Software engineers is making technical Software product and process design decisions. However, today there is a disconnect between the technical criteria taught to Software engineers and the strategic value creation objectives of the organizations for which Software is designed. This disconnect is reflected in the culture and the literature of Software design. For example, of sixteen books on Software architecture and object-oriented design surveyed, the word cost appeared in the index of only two. Part of the problem is that the links between technical concepts and value creation are not understood well, even in theory. We have an inadequate understanding of and a lack models for the connections between technical decision criteria and value. For example, we lack models for how information hiding modularity adds value to a system, and how much. Today this lack of understanding is intolerable. Software design and use decisions are coupled with fundamental business, public service, and other decisions in almost field. It is becoming critical to develop a better understanding of how Software design decisions relate to value creation. The second dimension of the problem is that existing knowledge in Software Economics is inadequate. To simplify, most present knowledge focuses on cost and risk reduction in traditional government or large industry projects; but today organizations are often driven more by competition and time-to-market as by direct cost. New life-cycle models and Software technologies are also being used that tend to invalidate the empirical bases of older models. The EDSER workshops seek to raise the visibility of the economic dimension of Software design and use and to foster the emergence and evaluation of Economics-oriented concepts, models and tools to improve Software production. The EDSER-2 Workshop was made possible in part by the National Science Foundation under grant CCR-9804078.

  • Software Pioneers - Early experiences in Software Economics
    Software Pioneers, 2020
    Co-Authors: Barry Boehm
    Abstract:

    My first exposure to Software Economics came on my first day in the Software business, in June 1955 at General Dynamics in San Diego. My supervisor took me on a walking tour through the computer, and ERA 1103, which occupied most of a large room. His most memorable comment was, “Now listen. We’re paying this computer six hundred dollars an hour, and we’re paying you two dollars an hour, and I want you to act accordingly.”

  • analyzing time pressure for Software Economics
    Journal of Enterprise Information Management, 2019
    Co-Authors: Seher Razzaq, Jianglin Huang
    Abstract:

    The research on people and project factors is found extensively in general but not specific to Software engineering. Secondly, the existing research has not concentrated on the communication and time complexity of the teams on Software Economics. The purpose this paper is to develop a model to investigate and quantify the impact of time pressure (TP) on Software Economics through the communication influence of Software team sizes (TS).,A research model and five hypotheses are developed based on the gaps in the literature. The data set from International Software Benchmarking Standards Group repository is used for testing the hypotheses.,Important findings include: smaller TS tends to exert less TP on average; TP is directly proportional to Software Economics, however; and TP does not affect the productivity required for the Software.,The study has the following implications: Selection of an appropriate TS for project completion that ensures minimum pressure on team members; and maximize Software outcomes in stress-free environment.,This work is useful for organizations carrying out Software projects with teamwork. The project managers can benefit from the results while planning the team factors for achieving the project goals.,The results uphold not to exert pressure on the team as it will not only affect the duly completion of the project but also the well-being of employees.,The paper is the first one where the proposition of TP estimation is done using TS and communication complexity, and empirically evaluating the impact of TP on four major Software Economics are the major key contributions of this research work.

  • IEEM - An empirical study of the impact of project factors on Software Economics
    2015 IEEE International Conference on Industrial Engineering and Engineering Management (IEEM), 2015
    Co-Authors: Jianglin Huang, Yan-fu Li
    Abstract:

    Software economic analysis supports practitioners making decisions during the development process. Effective analysis requires considering higher productivity and quality while maintaining lower effort and time-to-market for business demands. Former studies have identified multiple factors of team and project that determine Software Economics. However, there is serious conclusive inconsistency. Experts are calling for more empirical evidence with objective data. This study aims at validating the empirical relationships between team/project factors and Software economic measurement, including productivity, quality, effort, and time-to-market. The data analysis bases on a renowned dataset, ISBSG. Our findings indicate multiple factors, including team size, language type, and organization type, turn out to have a significant impact on Software Economics.

  • An Empirical Analysis of the Impact of Software Vulnerability Announcements on Firm Stock Price
    IEEE Transactions on Software Engineering, 2007
    Co-Authors: Rahul Telang, Sunil Wattal
    Abstract:

    Security defects in Software cost millions of dollars to firms in terms of downtime, disruptions, and confidentiality breaches. However, the economic implications of these defects for Software vendors are not well understood. Lack of legal liability and the presence of switching costs and network externalities may protect Software vendors from incurring significant costs in the event of a vulnerability announcement, unlike such industries as auto and pharmaceuticals, which have been known to suffer significant loss in market value in the event of a defect announcement. Although research in Software Economics has studied firms' incentives to improve overall quality, there have not been any studies which show that Software vendors have an incentive to invest in building more secure Software. The objectives of this paper are twofold. 1) We examine how a Software vendor's market value changes when a vulnerability is announced. 2) We examine how firm and vulnerability characteristics mediate the change in the market value of a vendor. We collect data from leading national newspapers and industry sources, such as the Computer Emergency Response Team (CERT), by searching for reports on published Software vulnerabilities. We show that vulnerability announcements lead to a negative and significant change in a Software vendor's market value. In our sample, on average, a vendor loses around 0.6 percent value in stock price when a vulnerability is reported. We find that a Software vendor loses more market share if the market is competitive or if the vendor is small. To provide further insight, we use the information content of the disclosure announcement to classify vulnerabilities into various types. We find that the change in stock price is more negative if the vendor fails to provide a patch at the time of disclosure. Also, more severe flaws have a significantly greater impact. Our analysis provides many interesting implications for Software vendors as well as policy makers.

  • impact of Software vulnerability announcements on the market value of Software vendors an empirical investigation
    WEIS, 2005
    Co-Authors: Rahul Telang, Sunil Wattal
    Abstract:

    Researchers in the area of information security have mainly been concerned with tools, techniques and policies that firms can use to protect themselves against security breaches. However, information security is as much about security Software as it is about secure Software. Software is not secure when it has defects or flaws which can be exploited by hackers to cause attacks such as unauthorized intrusion or denial of service attacks. Any public announcement makes about a Software defect is termed as 'vulnerability disclosure'. Although research in Software Economics have studied firms' incentive to improve overall quality, there have been no studies to show that Software vendors have an incentive to invest in building more secure Software. In this paper, we use the event study methodology to examine Software vendors' incentives to build more secure Software. We collect data from leading national newspapers and industry sources like CERT by searching for reports on published Software vulnerabilities. We show that vulnerability disclosures lead to a negative and significant change in market value for a Software vendor. On average, a vendor loses around 0.6% value in stock price when a vulnerability is reported. This is equivalent to a loss in market capitalization values of $0.86 billion per vulnerability announcement. To provide further insight, we use the information content of the disclosure announcement to classify vulnerabilities into various types. We find that the change in stock price is more negative if the vendor fails to provide a patch at the time of disclosure. Moreover, vulnerabilities which cause a confidentiality related breach cause a greater decline in the market value for a vendor than the vulnerabilities which cause non-confidentiality related breaches. Also, more severe flaws have a significantly greater impact than flaws with low or moderate severity. Finally, we find that the markets do not punish a Software vendor more severely if a third party discovers a flaw in its product than if the vendor itself discovers the flaw. Our analysis provides many interesting implications for Software vendors as well as policy makers.
