HATTINGH, E.; VAN WAVEREN, C.C.  e  CHAN, K.-Y.. A learning curve theory perspective on projects. Ranking the key determinants to improve project efficiency. S. Afr. J. Ind. Eng. [online]. 2019, vol.30, n.1, pp.37-53. ISSN 2224-7890.  http://dx.doi.org/10.7166/30-1-1886.

The desire to gain knowledge about the quality and timing of construction projects delivered to clients has become an increased focus point in the field of construction management. Clients have expectations that are often based on their assumptions about the validity of making the learning curve theory applicable to construction projects. This research aims to determine what criteria need to be met for the learning curve theory to have some validity for construction projects. The results from the questionnaire survey, completed by professionals from the construction industry, show that several concepts were found to be of importance: project specifications, design, scope, budget, site management, planning, monitoring and controlling, and quality. If these concepts correspond between two projects, the chance of successfully applying the learning curve theory increases. Practical recommendations are made that highlight the concepts identified as critical for the successful application of the learning curve theory to construction projects, and that can be used by clients and contractors as a basis for negotiating project schedules.
