Objectives and Core Topics
The primary objective of this thesis is to conceptualize and design an integrated portfolio management system tailored for software line development, effectively bridging the gap between existing software project and product management methodologies. The research aims to evaluate current portfolio and software line development theories to create a structured framework that assists organizations in aligning their development initiatives with broader business strategies.
- Theoretical and empirical analysis of portfolio management and software line engineering.
- Development of a multidimensional scoring model for portfolio analysis.
- Architectural design of a software line portfolio management system using the 4+1 view model.
- Validation of the proposed model through a practical case study within the EADS Cassidian division.
Excerpt from the Book
Limitations of Portfolio Management
1. Limited view: The most key figures of portfolio analysis are based on financial ratios like Return on Investment (ROI) or NPV. Ecological and technological factors play often none or only a small role. In addition to that qualitative measurable factors like communication in the organisation will frequently be disregarded (Jeffery & Leliveld, 2003).
2. Static point of view: The portfolio analysis can only analyse solutions based on present informations. Like all controlling instruments, the portfolio analysis tries to give future advices based on previous and current experiences. This is in general a high risk factor because of its uncertainty.
3. Inflexible approach: The portfolio controlling tries to establish a product portfolio derived from the company’s strategy. In contrast to that, this top-down approach is not always applicable. Enterprises which already have an existing portfolio are recomended to use a bottom-up or hybrid approach for their portfolio analysis. These two concepts aspire a step-wise alignment of the business portfolio with the organisation’s strategy instead of a total recommencement (Schmahl & Gleich, 2009, p. 35-38).
4. Oversimplified analysis methods: The portfolio analysis often considers only two or three key figures for solution selection. This simple analysis model often do not reflect the complexity of decision making in the real world. Therefore, the analysis charts shall only be seen as a direction sign. The final decisions have to be based on more detailed information like from scoring models (Cooper, Edgett & Kleinschmidt, 2001, p. 45-46).
Summary of Chapters
