Software migration projects are often bound either by time or cost or by both. If the project is bound by both time and cost, the user must sacrifice something else, usually the quality. The migration strategy depends on how the project is bound. ...

image image Redevelopment is often prohibitively expensive and/or fails. Automated conversion is error prone, delivers unmaintainable code, and is high risk. Reimplemention sits between conversion and redevelopment: the old business‐logic remains, only the ...

• Simple Excel spreadsheet for assessing the success potential of IT-outsourcing deals.

We implemented five easy-to-complete questionnaires in Excel, which could serve as early warning signals for practitioners interested in the odds of their IT-outsourcing deals and could serve to redirect their course when still ...

• Re-implementation as an alternative to redevelopment and conversion.
• Reverse-...

Re-implementation is one of the alternatives to migrate a legacy software system next to conversion, wrapping and redevelopment. It is a compromise solution between automated conversion and complete redevelopment. The technical ...

We present the findings from a Dutch field study of a representative sample of 30 outsourcing deals totalling to more than 100 million Euro, where both customers, corresponding IT-outsourcing providers and their intermediaries (if present) participated. ...

The lack of skilled programming personnel and the growing burden of maintaining customized software are forcing organizations to quit producing their own software. It's high time they turned to ready-made, standard components to fulfill their business ...

This paper is an industrial case study of how a VisualAge application system on an IBM mainframe was reverse engineered into a system reference repository. The starting point was the code fragments generated by the VisualAge interactive development ...

After outsourcing, issues can arise between the outsourcing organization and their third parties about fair payment. In a ceteris paribus situation, fair payment can be determined based on the differences made by the third parties. However, when ...

We focus on an approach to reducing the costs of running applications. MIPS, which is a traditional acronym for millions of instructions per second, have evolved to become a measurement of processing power and CPU resource consumption. The need for ...

Finding a balance between the time-to-market and quality of a delivered product is a daunting task. The optimal release moment is not easily found. We propose to use historical project data to monitor the progress of running projects. From the data we ...

This paper presents an analysis of the unit testing approach developed and used by the Core Flight Software System (CFS) product line team at the NASA Goddard Space Flight Center (GSFC). The goal of the analysis is to understand, review, and recommend ...

This paper presents a case for using standard services rather than developing one's own customized nuts and bolts software. It illustrates the size and complexity of object-oriented applications and defines what it costs to maintain them. The increasing ...

The following paper proposes a structured, natural language specification of web service behavior based on keywords in context. The advantage of this type of document is that it can be automatically analyzed in order to extract test cases for testing ...

This article discusses how to quantify the forecasting quality of IT business value. We address a common economic indicator often used to determine the business value of project proposals, the Net Present Value (NPV). To quantify the forecasting quality ...

In 1994, Standish published the Chaos report that showed a shocking 16 percent project success. This and renewed figures by Standish are often used to indicate that project management of application software development is in trouble. However, Standish'...

In this article, we show how to quantify the quality of IT forecasts. First, we analyze two metrics previously proposed to analyze IT forecast data-Boehm's cone of uncertainty and DeMarco's Estimating Quality Factor. We show theoretical problems with ...

A statistical method is proposed for quantifying the impact of factors that influence the quality of the estimation of costs for IT-enabled business projects. We call these factors risk drivers as they influence the risk of the misestimation of project ...

As the use of software and electronics in modern products is omnipresent and continuously increasing, companies in the embedded systems industry face increasing complexity in controlling and enabling the evolution of their IT-intensive products. ...

In an organization operating in the bancassurance sector we identified a low-risk IT subportfolio of 84 IT projects comprising together 16,500 function points, each project varying in size and duration, for which we were able to quantify its ...

We proposed a method to quantify the yield of an IT-investment portfolio in an environment of uncertainty and risk. For various common implementation scenarios such as growing demands during implementation without deadline extensions we showed how to ...
