Designing a preference-based accommodation strategy: A pilot study at Delft University of Technology

This paper aims to describe the development and test of such a design method to achieve alignment, which utilises the preference-based accommodation strategy (PAS) design procedure. One of the long-standing issues in the field of corporate real estate management is the alignment of an organisation’s real estate to its corporate strategy. A classification of alignment models shows that no model yet exists that is able to design a real estate portfolio and makes use of scales for direct measurement of added value/preference, and allows the aggregation of individual ratings into an overall performance rating.

To perform the steps in the PAS design procedure, a mathematical model is designed and tested according to formal design principles. The PAS design procedure is iteratively repeated with the participants in a series of interviews and workshops. In the interviews, the participants determine their preferences and constraints as prescribed in the procedure; in the workshops, they design alternative portfolios using the mathematical model. The objective of the research is to formulate, test and evaluate if participants are able to perform the PAS design procedure.

A methodology is developed for designing a real estate strategy that uses explicit scales for measuring value/preference and enables aggregating individual preference ratings into an overall rating taking into account both quantitative and qualitative portfolio properties. The tests of this design method with the participants reveal that by completing the steps in the PAS design procedure, users are able to determine their preferences accordingly. They were also able to design an alternative portfolio with a higher overall preference score than the current real estate portfolio. In addition, the design method is evaluated positively by the participants based on their experiences, the attractiveness of the method and perception of effectiveness of the method.

The positive results suggest that designing a strategy by using the PAS design procedure is a suitable approach to alignment.

The PAS design procedure enables corporate real estate (CRE) managers to determine the added value of a real estate strategy. Because the PAS design method is generic, it can be used for a wide range of real estate portfolios.

The first CRE alignment model uses stakeholders preferences to design a more optimal real estate strategy.
