5C is similar to the 5S.  Some overlap with some of the 5S and with other 5C.

Clear Out

Separate essential items from the non-essential. When items are no longer needed they should be put away.



Items (e.g. tools, materials, plant and documentation) used most frequently should be placed close at hand whilst those used less often should be further away or put away.  When an item is no longer frequently used it should be moved further away and the space used for items which are now used more frequently.

For example a worker may have a number of projects at any given times; some just started on, some in progress and some approaching or in closure.  Some may be active and high priority whilst some may be inactive (waiting on someone else to complete a task or an event) or low priority (so called 'back burner' projects to be worked on only when higher priority work is on hold).  Active and high priority project items should be close to hand whilst those for low priority project items should be accessible but not taking space that items for higher priority projects should be in.  Items for inactive projects may be temporarily put away until the project becomes active again.  Items for closed projects should be put away, archived or disposed of as appropriate.

This can also be applied to digital files on a computer system  (e.g. documents, source code, image files, data extracts &c) where a person may have a folder containing sub-folders for each current project.  The sub-folders are sorted by descending last access date so most recently used sub-folders (those for the most active projects) will be at the top whilst the less active project sub-folders can be found by scrolling down.  As projects are closed the sub-folders are moved to an archive folder and eventually deleted or moved to a separate archive as appropriate.


Clean and Check

All items (e.g. tools, plant, materials, furniture, documents, standards &c) used in the work (or to support the work) should be regularly cleaned and checked for fitness for purpose.  For physical items this might include checking for wear and tear or damage, removal of dirt, lubrication, stocktaking and confirming that items still comply to standards (including within use by dates for perishable items) and are still needed.  For documents and standards  this might include checking that they are the correct version, checking the completeness and legibility of hard copies, confirming that they still relate to the real world situation and updating or flagging for update.



Confirm that items are delivered to the required specification, cost and timescale.  Investigate any divergence from expected ranges.


Custom and Practice

Everyone should follow the same processes and understand the benefits of doing so.  Anyone who can see a way to improve processes has a channel to submit their improvements to a suitable level and, if they will lead to improvements, have them implemented and used by everyone.
