Software process improvement and software process assessment have received special attention since the 1980s. Some models have been created, but these models rest on a normative approach, where the decision-maker's participation in a software organization is limited to understanding which process is more relevant to each organization. The proposal of this work is to present the MCDA-C as a constructivist methodology for software process improvement and assessment. The methodology makes it possible to visualize the criteria that must be taken into account according to the decision-makers' values in the process improvement actions, making it possible to rank actions in the light of specific organizational needs. This process helped the manager of the company studied to focus on and prioritize process improvement actions. This paper offers an empirical understanding of the application of performance evaluation to software process improvement and identifies complementary tools to the normative models presented today.

“…The constructivist approach aims to generate knowledge in decision-making during the construction of the model, so that the decision-maker can understand the consequences of the current situation for his/her values and the evolution caused by his/her decisions for his/her strategic objectives (Roy, 1993;Tsoukias, 2008).…”

“…Pareto sorting tools that allow the user to identify optimal designs using smaller, simpler sub-problems within the larger multi-objective optimisation problem (Kollat and Reed, 2007b;Kollat et al, 2011;Reed and Kollat, 2012) should be incorporated directly in these frameworks, as should techniques that allow the user to "thin" the Pareto set based on meaningful precision (Kollat and Reed, 2007a;Laumanns et al, 2002). Additionally, advances toward adaptive software frameworks that more fully integrate the decision maker into the modelling, optimisation, and the decision making process as a continual feedback loop of learning and understanding will ultimately lead to better decision making (Roy, 1971;Tsoukias, 2008;Woodruff et al, 2013).…”

Research to date has emphasized algorithmic improvements and individual applications in specific areas (e.g., model calibration, water distribution systems, groundwater management, river-basin planning and management, etc.). However, there has been limited synthesis between shared problem traits, common EA challenges, and needed advances across major applications. This paper clarifies the current status and future research directions for better solving key water resources problems using EAs. Advances in understanding fitness landscape properties and their effects on algorithm performance are critical. Future EA-based applications to real-world problems require a fundamental shift of focus towards improving problem formulations, understanding general theoretic frameworks for problem decompositions, major advances in EA computational efficiency, and most importantly aiding real decision-making in complex, uncertain application contexts.

“…In fact, the evaluation models (and the evaluation method used to structure the problem and the decision process) are subject to a validation process that involves four steps: conceptual, logical, experimental and operational validation (Landry et al 1983). The aim of the validation process is to verify whether the key issues have been appropriately considered (Tsoukiàs 2007). The first part of the evaluation process took place in the experimental validation step.…”

Integrating multicriteria evaluation and data visualization as a problem structuring approach to support territorial transformation projects

Large freight or passenger transport projects are problematic and controversial because many financial, technical, environmental and social aspects need to be considered. Indeed, the interface between the transport project and territorial planning domains is generally the focus of considerable heated debates, which often develop into conflicting decision contexts characterized by a high level of complexity. This paper presents a possible response to these difficulties through an innovative approach that integrates the analytic network process and the interactive visualization tool. The approach is intended to be deployed as problem structuring method, with a view to creating a common language for the actors involved and a shared basis for generating fruitful discussions. The proposed approach was applied in the context of the German section of the Genoa-Rotterdam railway corridor within the Interreg IVB NWE Project ''Code24''. The reported application shows how the combination of visualization and real-time interaction with spatial data provided effective decision support to a multinational stakeholder group. More generally, the application presented in this paper aims to demonstrate the potential 123EURO J Decis Process (2014) 2:281-312 DOI 10.1007/s40070-014-0033-x of the approach for the selection of a transport improvement strategy within the content of territorial transformation.
