In the following, various components of the Work Proposal Proposal are elaborated; namely, a tools-based overview of approach to the product dissection, a projection on the duration of both the disassembly and the reassembly, and a chart identifying the strengths and corresponding weaknesses shared among the group's members. As such, details of the Work Proposal are developed in the content below.


Approaching the disassembly of the UT 15151 Homelite® VersaTool™ Line Trimmer with due caution and scrutiny, Group 29 has determined it will require the following tools to conduct adequately and proficiently its physical dissection of the product.

  • Set of sockets and ratchet
  • Torque wrench set
  • Standard wrench set and Crescent wrench
  • Pliers
  • (#2) Phillips head and flat-head screwdrivers

Duration of Disassembly

On condition that the Disassembly/Reassembly Technicians (please refer to the Management Proposal for a description of the responsibilities this position entails) convene a minimum of twice per week for two to three hours each visit, full dissection of the product, including its disassembly, is projected to consume two and one-half weeks of the project’s overall timeline. Despite hurdles foreseen in coordinating weekly groupwork in the face of conflicting personal schedules among members, the foregoing forecast proves sufficiently tenable. This is so in light of the members' relative familiarity with consumer products designed for lawn upkeep, and the Lead Technician's extensive exposure to line trimmer machinery and internal mechanisms of like devices, and a variety of small engines in general.

Duration of Reassembly

The reassembly, to which apply the conditions noted above for the duration of the disassembly as well, is estimated to last one week, as noted in more specificity on the Gantt chart contained in the Management Proposal. When accounting for the technical proficiency of the group as a whole, in particular the background knowledge specific to the product on the part of the Lead Technician, the time necessary for reassembling the product from its base components is both practical and equally far-seeing. That is, with a structured approach, well-defined orientation, and sustained concentration throughout the reverse engineering undertaking, product reassembly reduces, more or less, to a reversal of the procedure for disassembly, thereby allowing for findings from the dissection process to be applied to the component-wise construction of the product.

Challenges Encountered

Following a thorough initial inspection of the product, it appears corroded components and fasteners could complicate disassembly, or at least serve as a persistent reminder of the caution to be exercised throughout the course of the product’s disassembly and subsequent reassembly.

Competencies and Shortcomings

For a detailed distillation of the competencies shared among the members of Group 29, please refer to the chart below.

In regard to addressing the shortcomings of the group, the salient one proves to be coordinating times at which the group may convene as a whole to perform disassembly of the product. This is so, because individual schedules have thus far conflicted to a prominent degree, thus suggesting that substantial attention be directed in the near future to time management and ensuring that collective participation is sustained throughout the succession of the Gates. It is not for lack of will, but rather for the lack of time, that such an issue has evolved to be of principal concern for the group.

What follows is a charted summary of the fortes and deficiencies identified for each member as they pertain to the undertaking addressed herein.
