  1. 1. Exploring Software Cost Estimation Inaccuracy

    Author : Ana Magazinius; [2012]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; organizational politics; estimation inhibitors; project management; software cost and effort estimation; learning in organizations; informal use of estimates;

    Abstract : The inaccuracy of software cost estimates has for long been a source of frustration to software practitioners and cost estimation researchers. Despite huge efforts to improve this important practice, estimation accuracy is still low. This thesis uses empirical and theoretical evidence to investigate why this problem persists. READ MORE

  2. 2. Supporting Effort Estimation in Agile Software Development

    University dissertation from Karlskrona : Blekinge Tekniska Högskola

    Author : Muhammad Usman; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Background: In Agile Software Development (ASD) planning is valued more than the resulting plans. Planning and estimation are carried out at multiple levels in ASD. Agile plans and estimates are frequently updated to reflect the current situation. It supports shorter release cycles and flexibility to incorporate changing market and customer needs. READ MORE

  3. 3. Exploring Cost Estimation Inaccuracy - Why do practitioners still fail to predict the actuals?

    University dissertation from Karlskrona : Blekinge Tekniska Högskola

    Author : Ana Magazinovic; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Software Development Cost Estimation;

    Abstract : The purpose of this research is to further explore why practitioners’ ability to predict actual results is still not satisfactory. This problem was investigated from two perspectives. First, the practitioners view on causes of inaccurate cost estimates was explored in a quantitative multiple case study. READ MORE

  4. 4. Knowledge Classification for Supporting Effort Estimation in Global Software Engineering Projects

    University dissertation from Karlskrona : Blekinge Tekniska Högskola

    Author : Ricardo Britto; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Background: Global Software Engineering (GSE) has become a widely applied operational model for the development of software systems; it can increase profits and decrease time-to-market. However, there are many challenges associated with development of software in a globally distributed fashion. READ MORE

  5. 5. Quasi-analytical Modelling and Optimisation Techniques for Transport Aircraft Design

    University dissertation from Institutionen för flygteknik

    Author : Askin T. Isikveren; [2002]
    Keywords : aircraft; conceptual; design; specifications; atmosphere; geometry; weight; aerodyanmics; propulsion; operational performance; stability and control; constrained multi-objective optimisation; computer aided design; regional; business; high-transonic; ;

    Abstract : The research work presented here focuses on the subject oftransport aircraft design at the pre-design or conceptuallevel. The primary topics addressed are: (1) generation of avast array of new quasi-analytical expressions to permit aconceptual treatment of commercial and business transportaircraft with adequate sensitivity for more advanced tradestudies; (2) review and adoption of a method to predictstability and control characteristics (using the Mitchellmethod); (3) a study of the relative merits between variousmethods in facilitating an expedient and robust constrainedmulti-objective optimisation result within the context oftraditional conceptual design problems (Genetic Algorithms andNelder-Mead Simplex search); (4) creation of a software packageas a new and unique conceptual tool that permits the generationof design proposals in an accurate yet expeditious manner; and,(5) practical demonstration of the new conceptual designsoftware package by undertaking some actual aircraft designproposals.
