To address these concerns, an instrumental case study approach was undertaken using a series of site investigations and interviews with experts and stakeholders. Li and Henry [15] conducted a case study on two industrial systems written in Ada, and found that software size is an important predictor for maintenance effort. The aim of this research was to strengthen the knowledge base on high-rise vertical greenery facades in the tropics, leading to the formulation of case study-based ‘design for maintainability’ (DfM) guidelines. <>stream The body of knowledge on design for maintainability (DfM) is increasing.

Design of Experiments (DOE) provides a methodology to create organized test plans to identify important variables, to estimate their effect on a certain product characteristic and to optimize the settings of these variables to improve the design robustness. It is held that the computed conditional probability values can be generalized to the population because the output is an estimator based on sample buildings.
