• Indication method: Energy consumption or Energy intensity
• Target value: Decide on the basis of actual value, or
  Decide on the basis of theoretical calculation value
  (Minimum value, maximum value, optimum value), or
  Decide on the basis of facility design value or nominal capacity value.
  
• Who establishes the target?
  Engineer establishes the target ? This is the ordinary way, aside from situations where theoretical calculation is necessary. or,
  Operator establishes the target (subject to engineer's approval) ? In such cases where a target is considered on the basis of actual value. or,
  Manager establishes the target ? by counting backward from the necessary reduction in cost.

- It may also relate to the level of improvement.

• Who takes the leading role in the establishment and implementation of the counter measure and
• Who will be the leader of the promotion of the activity
  - depends on the improvement level to be achieved as outlined in the "Step of improvement."

In general,

"Step 1": improvement at operation management level, the operators
can take a leading role, and the engineer cooperates in giving advice.

"Step 2": improvement, the engineer takes a leading role, and he respects the operator's opinion.
<in some cases participation of the energy manager is required>

"Step 3": improvement, the engineer takes a leading role for studying the measure, but the executive officer decides
whether the measure will be carried out or not.
<participation of the energy manager is necessary, because
the total energy balance of the hole factory should be considered.>
