3. Measure Executive Summary
- Improve tank maintenance quality by giving the 1/16 soldiers more time to perform maintenance during the draw.
- The project starts at the FTX/STX2 T-6 IPR and ends when the tanks are ready for HETT transport.This project is contained within the Fort Knox Garrison and can transfer to other training support missions on Fort Knox.
- We are feeling the pain in training and tank maintenance.
- Soldiers fail to do a quality PMCS for the lack of time, training, and command emphasis.
4. Project Charter Review
- Scope:this process begins with the T-6 IPR and ends when 1/16 loads the tanks on HETTs.
- Goal: Improve tank draw quality
Problem/Goal Statement Tollgate Review Schedule Business Impact Core Team
- State financial impact of project
- Revenues-potential savings in time and material TBD
- Non-Quantifiable Benefits are increased tank maintenance quality, soldiers morale, maintenance fault tracking, and less training time lost.

- Reduce rework during tank draw from 90% to 45%, per FTX/STX2 by 1 October 2008.
- Improve 5988-E fault tracking during tank draw from 10% to 85%, per FTX/STX2 by 1 October 2008.
- Improve tank bumper number accuracy from 10% to 90%, during the T-2 preparation week by 1 October 2008.
Problem StatementSoldiers of 1/16 express dissatisfaction with the Unit Maintenance Activities M1 series tank quality prior to mission support. Currently, 90% of the tanks drawn require maintenance for mission readiness.Approximately 10% of faults listed on the 5988-E s completed by soldiers are tracked by UMA.Lastly, tank bumper number accuracy during T-2 is currently at 10% which causes excess work in the last days of the mission support draw. 5.

M1 series Draw Process 9. Operational Definitions
- Y Continuous data-Process starts at the T-6 IPR and stops when the tanks are staged in the motor pool awaiting HETT movement.The cycle time boundaries are the UMAs hours of operation (0730-1530, M-F) and the units of measure are hours and individual faults. The unit of measurement is tank quality, and weekends, holidays, and non-business hours are not included.
- Y Discrete data-Success is a tank bumper number given to a soldier to draw for a tank that is ready for training. A defect is work that has to be done to make the tank ready for training after the bumper number has been given to the unit.Also, success is a 5988-E that is correctly completed by a soldier and updated by the UMA within 7 days of receipt.A defect is an incorrectly completed 5988-E (by the soldier), or a correctly completed 5988-E that the UMA fails to update within 7 days.
- X Draw times of other events that effect tank quality. These areas under examination are the Contracts Process, and BII issue points
