Causes for corrective action
Overall, all of our goals were accomplished in good time. Individually, all of our members were able to contribute constructively and in a timely manner. Since the dissection required coordination with the other team (Group 18), we agreed on a Wednesday meeting time and was able to complete the dissection by the 26th. Problems arose as several members were ill but we were able to keep in contact and complete the dissection. Regrettably, we were not present for the last dissection session that took place on Monday however the steps have been included in our report nonetheless.
Difficulty Key to Disassembly Process
Difficulty of the described step is expressed on a scale of 5 and can be expressed as:
- Level 1
- Requires small and/or simple tools (e.g. Screwdriver, Socket Wrench).
- Requires minimal use of force.
- Removed parts are small with few fasteners (e.g. Bolts).
- Requires no more than one person to complete.
- Level 2
- Requires small and/or simple tools.
- Requires minimal use of force.
- Removed parts are small or delicate usually with a numbers of fasteners.
- Requires one person but also close attention.
- Level 3
- May require slightly larger tools (e.g. Hammer/Mallet).
- May require use of light force.
- Removed parts may be complex but large and need attention to prevent damage.
- Significant number of fasteners that require attention.
- May require 2 individuals working side by side.
- Level 4
- Requires use of larger and possibly specialized tools (e.g. Valve Spring Compressors).
- Requires considerable use of force.
- Parts removed are numerous and/or large and heavy making them difficult to move and store.
- Requires 2 or 3 individuals working simultaneously.
- Level 5
- Requires largest and specialized tools that require the use of force (e.g. Pulley Puller).
- Requires most use of force (possibly involving more than one individual).
- Removed parts are very large, with numerous fasteners and/or delicate parts.
- Removed parts are heavy and hard to move.
- Requires 3 people working simultaneously to complete the task or tasks.
