The design stage considered as one of the essential stages of engineering project life cycle. Even the quality requirements at this stage would be a basis to the next levels of preparation, construction and maintenance. The main objective of this research is study the quality and confirming it in the design phase, also how it can be employed technical grounds (The Method of Multiple Criteria Complex Proportional Assessment (COPRAS)). COPRAS method consists of alternatives and criteria, in this research there are five companies alternatives classified as consulting engineering companies which are (A1, A2, A3, A4 and A5) and twelve main criteria collected from previous works and studies. As a result of conducted research, the controlling of design output is one of the main design quality criteria which had the highest relative importance was in comparison with all other criteria, in addition, the evaluation was various between the companies, where the company A4 obtained the highest assessment while the company A2 had the lowest evaluation, but in general, the design quality in the Jordanian companies is weak. So the proposed framework and the obtained results can help stakeholders of projects in Jordanian companies to get better understanding manage the design phase. Finaly, it recommended to use the application of techniques of decision- making multi-criteria in the evaluation of project in addition to expediting the application of the systems proposed by the researcher for the design quality management to help engineers on the best implementation of this administration.
