The decision-making process is crucial for selecting the best design alternative that meets all requirements. It involves a quantitative assessment of each design option through a simple matrix, where alternatives are listed in rows and evaluation criteria in columns, aligned with design goals. Weighting (1-10) reflects the significance of each goal, while raw scores (1-5) are clearly defined to justify evaluations. This structured approach ensures that the chosen design excels in achieving the defined objectives, ultimately leading to greater customer satisfaction.

The decision process should lead to the best solution • Proposed design alternatives must comply with all design requirements at this stage • The decision process quantitatively assesses each design alternative with respect to the design goals
The decision process takes the form of a simple matrix that allows one to quantitatively determine the best solution • The rows of the matrix list the design alternatives being evaluated • The columns of the matrix list the criteria by which the design alternatives will be judged (i.e. the design goals) • wt - weighting (1 - 10 ??) indicates the importance of a particular design goal to the product design (the overall satisfaction of the customer with the product) • raw - raw score (1 - 5 ??) basis/reasons for giving a design a particular raw score should be clearly defined (some raw score scale should be developed) • The design chosen is the one which is superior with respect to the design goals
