***************** Inventory – Solutions to Causes
In our last newsletter we discussed causes of waste by keeping inventory. This and the next few issues will share some answers:
Cause: Poor quality work in the shop and in the field
Solution: This is an age-old challenge in construction. The solution is straightforward but not easy. To improve quality it starts with a clear definition of what is and is not quality work. It can’t be wishy – washy such as “I know it when I see it!” Once defined all workers need to understand the quality requirements and that they are expected to meet the requirements. Work handed to them that does not meet the requirements should be sent back for rework. The work that they perform should be reviewed by them to ensure quality before passing it on. At Toyota they say – Don’t get it – Don’t make it – Don’t send it, in terms of bad quality. To produce quality work one must be committed to doing it right the first time, measuring poor quality and implementing prevention countermeasures through root cause analysis. It all starts with supervision believing that defects can be eliminated and prevented, and not passed on.
