‘Waiting For Parts…’

THE ISSUE: ‘Waiting for parts’ is a common reason given for jobs taking a long time to complete

THE SOLUTION1.Identify commonly used parts based on 1 year’s maintenance history2.Identify parts with extended lead times3.Build up reserve of parts with extended lead times by stripping out closed sites or ordering in advance

4

Clearer Reporting:

THE ISSUE: Standard reporting metrics (arrive on time, first fix rate etc.) didn’t appear to tell the whole story

THE SOLUTION: Report on entire ‘time to fix’- show how long a job takes to fix from beginning to end

5

ASSET TAGGING:

THE PROBLEM:

•Anecdotal awareness of ‘the same item failing time and time again’•No way of validating this•No way of identifying and tackling individual refrigeration units or types of refrigeration units that are failing frequently•Confusion when chasing up fixes, especially if store has more than 1 refrigeration issue ongoing

THE SOLUTION….

6

ASSET TAGGING:

THE SOLUTION: System numbers of refrigeration units incorporated into helpdesk system.

Stores will be asked for the unit number of fridges/freezers when logging faults, meaning…

•Easier identification of units that are repeatedly failing•Less confusion when updating/chasing jobs •Clearer reporting on which assets in the estate are faulty.•Production of ‘% Uptime’ statistics from July onwards

7

OTHER PRE-SUMMER IMPROVEMENTS:

Case Cleans:

•Refrigeration case cleans undertaken at 25 sites (selected based on history of failure or known issues)•Intensive clean includes chemical clean, nitrogen blow out and fin realignment

8

OTHER PRE-SUMMER IMPROVEMENTS:

•Common fault sites – investigations commissioned at sites with high levels of refrigeration faults •Contractor ‘league table’ for refrigeration – contractors benchmarked against each other on performance •‘Equipment Off’ report – weekly report generated on all refrigeration that has failed in the estate
