The construction industry needs to move towards more relational procurement procedures to\nreduce extensive losses of value and avoid conflicts and disputes. Despite this, the actual\nconceptualization and assessment of relationships during conflict and dispute incidents seem to\nbe neglected. Via a review of literature, relationship quality is suggested as a systematic\nframework for construction projects. General system theory is applied and a framework\nconsistent of four layers respectively labelled as triggering, antecedent, moderation and outcome\nis suggested. Two different case studies are undertaken to represent the systematic framework;\nwhich verifies that changes in contracting circumstances and built environment culture can affect\nthe identified layers.\nThrough system reliability theories a fault tree is derived to represent a systematic framework of\nrelationship quality. The combinations of components, causes, and events for two case studies\nare mapped out through fault tree. By analysing the fault tree the combination of events that lead\nto relationship deterioration may be identified. Consequently the progression of simple events\ninto failure is formulized and probabilities allocated. Accordingly the importance and the\ncontribution of these events to failure become accessible. The ability to have such indications\nabout relationship quality may help increase performance as well as sustainable procurement.
