Critical Analysis of the Duration Estimation Method

Oct 13, 2025 by wbrum.org 12 views

Introduction

The Phase III Development Project Regional General Hospital (RSUD) Dr. Djoelham in the city of Binjai began on June 30, 2011, with the aim of providing quality healthcare services to the community. However, the project faced significant challenges in completing the project within the scheduled timeframe of 182 calendar days. The application of deterministic duration methods in each activity proved to be inadequate in guaranteeing the project's timely completion. This article discusses the estimated risk -based duration approach used in the project, which integrated risk scale on each item of activities on a critical trajectory to ensure the project's completion on time.

Background

The Phase III Development Project RSUD Dr. Djoelham was initiated to address the growing healthcare needs of the community. The project's objective was to construct a modern hospital that would provide quality healthcare services to the people of Binjai. However, the project's implementation was marred by delays and cost overruns, which led to the project's completion being delayed beyond the scheduled timeframe.

Methodology

The estimated risk -based duration approach used in the project involved two methods: qualitative and quantitative. The qualitative method was used to determine the risk scale of each activity item, while the quantitative method was used to find the probability and optimal duration of project completion. The Evaluation and Review Technique (Pert) program was used to analyze the project's duration, which was integrated with the Monte Carlo simulation.

Analysis

The analysis of the project's duration was conducted in three scenarios: optimistic duration (most quickly completed), the most likely duration (most likely), and pessimistic duration (the longest completed). The results of the analysis showed that the project's probability of being completed on time was only 29.45%. The optimal duration of the project completion in the probability of 95% was 200 days.

Critical Analysis of the Duration Estimation Method

The selection of the exact duration estimation method is crucial in project management. Deterministic methods are often too rigid and do not consider random or unexpected factors, which can affect the project completion time. Conversely, risk -based methods provide better flexibility by considering the possibility of various scenarios that can occur during project implementation.

Importance of Understanding and Managing Risks

The importance of understanding and managing risks in the project cannot be ignored. Complex projects, such as the construction of hospitals, have many variables that interact with each other. Therefore, the use of techniques such as the Monte Carlo simulation in risk analysis is very important to provide a clearer picture of the variability of completion time.

Conclusion

The analysis and estimation of risk -based duration not only offers a way to achieve timely settlement but also improves the ability of project management in facing challenges and uncertainties that may arise during the development process. Phase III Development Project RSUD Dr. Djoelham provides valuable lessons about the importance of using the right method in the estimated duration, which can be adopted by similar projects in the future.

Recommendations

Based on the analysis and findings of this study, the following recommendations are made:

The use of risk -based methods in duration estimation should be adopted in similar projects to ensure timely completion.
The Monte Carlo simulation should be used in risk analysis to provide a clearer picture of the variability of completion time.
Project managers should consider the possibility of various scenarios that can occur during project implementation and plan accordingly.

Limitations of the Study

This study has several limitations, including:

The study was conducted on a single project, and the findings may not be generalizable to other projects.
The study only considered the duration estimation method and did not consider other factors that may affect project completion.

Future Research Directions

Future research should focus on:

Developing a more comprehensive risk -based duration estimation method that considers multiple factors that may affect project completion.
Conducting a larger-scale study to validate the findings of this study.
Investigating the use of other risk analysis techniques, such as sensitivity analysis and decision trees, in project management.
