4.1. First Batch of data collection

Based on data from 220 questionnaires, we conducted a quantitative analysis using IBM-SPSS. The following abbreviations were used in this analysis: AMC means aircraft manufacturing corporation and SBC means shipbuilding corporation.

Hypothesis
1. EBITDA is the proper measure of Project Management Profitability because it excludes Interest, Tax, Depreciation, and Amortization, which do not vary due to the Project Management efficiency and productivity variation.
2. EBITDA is the proper measure of Project Management Profitability because EBITDA is fully under the control of the Project Manager and Team.
3. The Company can maximize EBITDA with EVM in Project Management by integrating EBITDA to WBS and applying target EBITDA margin in every work breakdown structure and work package.
4. Using EBITDA as a measure of Project Management Profitability allows Project Managers and Teams to actively manage and maximize Project Management Profitability.
5. Applying EBITDA to EVM and WBS enables companies to display and control Project Management Profitability daily.
6. The Company can improve its ability to support Project management by sharing the daily Target and Actual EBITDA result with its supporting Units.
7. The Company can improve its ability to support Project management by sharing the daily Target and Actual EBITDA with the Board of Directors to provide timely strategic decisions to Project management.
