Lean Project Planning (LPP) is a new approach for project planning that has been developed from the Last Planner System to overcome shortcomings in the Earned Value Management approach. In this paper, we investigate how LPP has been successfully used in shipbuilding of a so called Platform Supply Vessel. Due to the highly advanced vessel, we managed to stress-test the approach and found a number of improvements to be made. However, the overall judgment is that LPP is a success. By now, these improvements are more or less implemented except those relevant for the engineering part. When it comes to the engineering processes further improvements are still needed.

The earned value management method is commonly used for monitoring and assessing project budget and schedule performance. Although widely used, this method does not consider the time value of money. This paper suggests the inclusion of inflation as a factor affecting project performance and gives a methodology to do so using the net present value. This is done by adjusting the present value and actual cost of the work packages. The result is more realistic progress measurements and performance indicators.

Earned value management is well-known as the most efficient method of project monitoring and control providing relatively reliable information about the project performance. However, this method requires accurate estimates of the progress of project activities, which are always associated with uncertainties that, if ignored or not addressed well, lead to incorrect results. To address this issue, the application of multi-valued logic, in particular fuzzy logic, in earned value management has recently attracted a lot of attention both in practice and research. This paper introduces directed earned value management (DEVM) in which ordered fuzzy numbers are used to express the so-called uncertainties as well as to capture more information about the trend of the project progress. To evaluate the performance of the proposed method, several numerical examples and a case study are presented. The results reveal that compared to the existing methods, DEVM has a lower computational complexity. Also, it doesn’t suffer from the overestimation effect and as a result, it has a higher ability to express project-specific dynamics. In sum, the proposed method allows project managers to make informed decisions that lead to taking preventive and corrective actions promptly and at a lower cost.
