The output predictions, therefore, are affected by variance in the project details P and variance in the internal tunings T. Local data is often used to constrain the internal tunings (reducing T). \u0000 \u0000While constraining internal tunings with local data is always the preferred option, there exist some models for which constraining tuning is optional. We show empirically that, for the USC COCOMO family of models, the effects of P dominate the effects of T i.e. the output variance of these models can be controlled without using local data to constrain the tuning variance (in ten case studies, we show that the estimates generated by only constraining P are very similar to those produced by constraining T with historical data). \u0000 \u0000We conclude that, if possible, models should be designed such that the effects of the project options dominate the effects of the tuning options. Such models can be used for the purposes of decision making without elaborate, tedious, and time-consuming data collection from the local domain.

In contrast, appreciative inquiry is a strength-based approach focusing on bringing forward the best in people and organizations to achieve successful change. While there is a significant research on SPI initiatives and the use of problem-oriented approaches there is limited knowledge about the way in which SPI initiatives unfolds when adopting a strength-based approach. Therefore, it is interesting to explore how software organizations familiar with problem-solving approaches experience the use of a strength-based approach. We present an action research study conducted at the Swedish telecom company Ericsson using appreciative inquiry to facilitate an SPI initiative implementing a new process and tool for the requirements and test case management. While the SPI initiative was considered successful, important lessons were learned regarding the use of appreciative inquiry. We conclude that the use of appreciative inquiry does not eliminate the dependence on other well-known key factors for SPI success. Also, our study indicates that the problem-solving mind-set, i.e. the satisfaction of identifying and solving problems, found among many software engineers familiar with problem-oriented approaches may impede the use of appreciative inquiry.

The interest in process improvement and maturity and capability models appears to be contagious as it grips an ever increasing number of domains and disciplines ranging from testing to risk management and from project management to organisational leadership. What they share is the pursuit of improvement goals that can translate into enhanced organisational capability and performance. This issue brings together the global experiences and new ideas of different organisations. Gaining a high level of maturity is defined as a target by an increasing number of organisations. However, sustaining performance at a high level implies being able to evolve the process continuously to meet changing needs and expectations. Improvement can be facilitated through the identification and addressing of strengths and weaknesses. The paper by Malheiros, Paim and Mendonca describes the lessons learned by Serpo, the largest (IT) services company in Latin America which is owned by the Brazilian Government. The organisation has thousands of developers spread over multiple units and areas.

Strategic release planning aims at assigning features to subsequent releases such that technical, resource, risk and budget constraints are met. Operational release planning focuses on the development of a single software release. Its purpose is to assign resources to feature development tasks such that total release duration is minimized under given process and project constraints. Replanning becomes necessary on the operational level because of addition or deletion of features during release development, due to changes in the workforce, or due to changes in process and project constraints. The allocation of resources to feature development tasks depends on the accurate estimation of planning parameters like task size, developer productivity or dependencies between task types. Risk analysis can help assess the reliability of a chosen release plan due to variation in these dependencies. In this article, we present elements of a simulation-based methodology to planning, replanning and risk analysis of software releases on an operational level. Even though there exist approaches addressing these three aspects individually, our proposed approach combines all of them into one single package and, hence, offers stronger support to decision makers. The core element of the methodology is the process simulation model REPSIM-2 (Release Plan Simulator, Version 2). We describe the functionality of REPSIM-2 and illustrate its usefulness for planning, replanning and risk analysis through application scenarios.

There are few studies of outsourcing presented from the viewpoint of the supplier. Given that more and more Chinese software companies are getting software outsourcing subcontracts from all over the world, it is important to understand how software outsourcing projects are actually performed in China, and to identify ways in which performance might be improved. Our study first collected data through a questionnaire-based survey from 53 finished projects in 41 Chinese software suppliers. A follow-up study was performed by telephone interviews with 11 participants, to find explanations for phenomena revealed by the preceding survey. The results show that: (a) differences in natural languages are not a real obstacle for Chinese software suppliers; (b) e-mail is most used to discuss issues related to development, while face-to-face meetings are mainly used to discuss issues related to management and requirements; and (c) the two main reasons for overtime work at the Chinese suppliers are changes to the design or requirements that are proposed by the outsourcers and the suppliers' initial underestimation of the effort required.
