Challenges Managing Duplicate Parts

Posted by Ryan Donovan on Sep 1, 2015 12:11:00 PM

1. Overview

Duplicates and near duplicates add costs throughout a products lifecycle, so it sensible to standardize on parts and avoid creating redundant or duplicate parts. Identifying duplicates and near duplicates is a cost effective exercise with excellent ROIs.

Finding exact duplicates is not too difficult, however identifying near duplicates can be difficult. For example, two screws might have the same thread size, same length, and same coatings. Viewing the items in a stock room, it might not be able to tell the screws apart. However, the material strengths of the screws might be different and to haplessly swap the screws could have catastrophic results.

Part Proliferation – Organizational Impact

Posted by Ryan Donovan on Aug 19, 2015 10:31:00 AM

1. Why is Duplicate Part Proliferation overlooked?

It is unfortunate to overlook the proliferation of duplicate parts, since eliminating duplicates or near duplicates is an excellent opportunity to improve design and save money.

  1. Duplicate part proliferation is underappreciated since the costs are not readily apparent nor fully understood.
  2. Non-existing or inadequate search tools and processes to find appropriate parts and identify duplicate parts complicate the situation.
  3. Short-term deadlines to complete a design take priority ahead of longer-term cost savings from reducing duplicates.

Part Proliferation – Who Is Responsible?

Posted by Ryan Donovan on Aug 19, 2015 10:12:00 AM

The costs of new and duplicate parts are dispersed over multiple departments and across products’ lifecycles, so it is difficult to identify who should be responsible for preventing part proliferation.

A closer look at a product’s lifecycle and the group responsible for most of the costs suggests engineering should be responsible of governing new part creation and preventing duplicate part creation.

2 Approaches to Cleansing Data

Posted by Ryan Donovan on Aug 19, 2015 10:10:00 AM

1. So you realize your data is a mess

Do you have good data? Can your engineers and designers quickly find parts to 

complete their design? Is your part data complete enough to determine if duplicates exist? Are your descriptions consistent and complete enough to sufficiently describe the form and functional specifications of the part? If you answered no, then perhaps it is time to cleanse your data.

After realizing you need to cleanse your data, the question becomes how to clean the data.

Design Costs Link to Classification

Posted by Ryan Donovan on Aug 19, 2015 10:08:00 AM

1. Classification: - a simple concept saves money and time

Companies can leverage classification to reduce design costs. The scientific community regularly uses classification to understand relations among items, with the plant and animal classification schemes perhaps the most familiar.

A classification scheme groups relevant components in a logical and systematic hierarchy and brings technically similar items together, yet uses attributes to distinguish them by their specific details. A classification scheme embraces all existing items and is able to accept new items into the component population using attributes to create mutually exclusive locations for similar components and excluding dissimilar components.
