Abstract :

The delay of accomplishing business process milestones in Exploration Function was an impact of organizational transformation that includes re-grouping of working area and manpower of multiple subsidiary entities into one region. Only two wells managed to be drilled out of six targeted wells. The bottleneck issue lies in the proposal phase of the exploration well drilling investment. Report documents, interviews, and focus group discussion are collected as data for this research. The root causes were found in several stages along proposal phase and coming from process, people, and data aspect. The qualitative analysis of this research applied process mapping analysis to understand the dependency of each task, and value-added – non-value-added activity analysis to define the importance of each task. The result is corrective actions proposed to cut time duration through several treatments towards specific processes. Sequentially, the quantitative analysis of this research applied that new process mapping and use the time of events on the following execution phase as the time limit to estimate the new time duration for each task. The managerial implication of this research is the generation of a metric for project scheduling.
