Context - Background

Our workflow optimization project leverages manufacturing based quality improvement methods, such as Lean and Six Sigma, which strive for zero “defects” as a measure of quality.

We have implemented a change management infrastructure that utilizes data collection and analysis to aid decision making

Context: Background

In order to analyze the type and kind of defects occurring in our workflows, we strove to implement a “defect reporting system” that would fit into the entire staff’s workflow for real time collection, whether they worked at a workstation that included a computer, or not.

Definition of Defect: a flaw, an imperfection, or a deficiency in specimen

processing that requires us to delay or stop our work or return work to the sender. We interpreted this definition to apply to all aspects of case

workflow Types of waste included process flaws associated with

overproduction, time waiting, transportation, processing, stock on hand, movement, defective products, dictation problems, etc…

Criteria for a optimal Defect Reporting System:

Easy to use Real-time data capture Equal access to all Standardized Menu-drive Defect capture closest to

discovery

Visual presentation and public exposure

Blameless participation Compliance with

participation Reusability.

Technology:

We utilized paper-based customized Post-it® (3M) notes with a 4 quadrant design, and developed a custom data entry form in PathStation, our VB.Net/SQL based workflow integration software application. (previously described)

Design A coded defect classification and location/process list was developed and

distributed to all employees. The data collection event lasted for 12 working days. For non-computer based workstations, defects were captured in real-time using

the custom designed Post-it notes using the coded choices Completed Post-it® notes were posted in each lab at designated “ wall” locations. We did not have space for Visual Data Displays, described by D’angelo et al due to

space constraints. Notes were collected every other day for data entry into the electronic module.

Running totals were reported back to each area on an ongoing basis For computer based settings, an integrated “defect” collection module

automatically set user context, case context, date/time, user location, and utilized an identical defect classification. A running total was always visible in the module. All entered defects were visible and sortable on a display tab. Ultimately, all defects were recorded into the electronic module to facilitate visibility to

the widest possible audience and allow for data analysis.

Indicating where the defect occurred

To indicate the location where the defect or process has occurred click on the dropdown arrow to the left of the <Defect/Process Location> field and select a location. Location codes are grouped by major areas. Note this is not the location documented. We automatically set this by where PC device name and known location for all PC’s,

Conclusions

The ability to document “defects” in real-time enhances reporting opportunities and increases compliance with data gathering events, critical to designing improvements that optimize efficiency and quality.

We demonstrate the ability to document the defect identified in less than 5 seconds in settings with, and without, a computer workstation.
