Improve Phase - Develop improvement solutions for the critical X's.

Following on from the Analyse phase and proposed solutions/actions generated from the brainstorming, fishbone diagram and cause and effect analysis the team decided to introduce inspection at Coat Prep for moulding string: Post our moulding process and also during the coat prep process, moulding machine drool string can attach to the distal end of the catheters resulting in a high potential for kinks during seperation of units. To reduce drool factor an extraction system will be added to the Moulding room.

We then drew up our assessment criteria and the Team developed a consensus using multi voting in which team members apportioned 100 points across the assessment criteria.

"Will not impact Quality" and "Will solve the Problem" were deemed most important.

Weighting of assessment criteria

As well as introducing inspection to coat prep and reducing string from the moulding machine introduction of a tip trimming fixture for Tip Form and optimising the position of the tree which holds the catheters during moulding were our top solutions.

As a Team we assessed each proposed solution by scoring each item with a rating of 1 - 10 (10 being best) and summing up the combined weighted score we then drew up a prioritisation matrix.



Tip Trimming Fixture:

We are now ready to move onto the final stage the control phase.
