'Lean Laboratory' aims to optimize productivity and efficiency, whilst eliminating any steps that do not add value. That's why one aspect of 'Lean Laboratory' is the systematic elimination of laboratory wastes. The principle is to identify and then reduce or eliminate the time-wasting or unnecessary steps, in order to improve the efficiency and simplify the overall process.

'Lean Management' describes 8 types of laboratory wastes that exist in a business – independent of the industry – which do not add any value for the customer.  

These 8 laboratory wastes, often described as DOWNTIME, are:

  1. Defects
  2. Over-production
  3. Waiting time
  4. Not engaging all employees
  5. Transportation
  6. Inventory
  7. Motion and
  8. Extra processing. 

One of the 8 wastes is waiting time. See below how you can reduce it:

  • Waiting time

Stagnating or idle processes, missing materials, defective or unsuitable resources, can all tie up resources which cannot be used during this waiting time.

Lean Lab Wastes
  • Weighing Example

Bench space in the lab is limited and an optimized weighing location is often difficult to find. Lab staff are walking around, the lab door is often used, air conditioning systems are not ideal. The balance is therefore often unstable with a long settling time

  • Possible Improvements

Use balances with SmartPan or SmartGrid to weigh under difficult environmental conditions

  • Moisture Analysis Example

Repeatability of moisture results is seriously impaired by drafts, windows and air-conditioning units. Second measurements are often necessary for this reason. Moisture methods have not been optimized and take too long (>15 minutes)

  • Possible Improvements

Proper location of the moisture analyzer is critical. Often overlooked by lab managers, the halogen moisture analyzer should be located carefully in the lab
