Controlling

• A feedback system combines planning, reporting,
  status analysis, deviation analysis and
  corrective measures

Planning
Status
Corrective action
Deviation analysis
5
Input/output analysis

• Consistent data
• Illustrates efficiency
• Evaluation criteria
• Quantities
• Financial values
• Environmental and toxicological properties

6
Safe on the road?
Which indicators?
7
Healthy or not?
Which indicators?

Aims of indicators

• Comparison of the actual to the planned situation
• Comparison of companies
• Comparison of variations over a period of time

9
Development of a set of indicators
Mass balances and costs
Targets
Targets reduction of material
losses, substitution, cost reduction, environmenta
l improvement, data compression, presentation,
analysis, control, decision making.
Set of indicators

Types of indicators

• Absolute figures
• Basic data (annual consumption, turnover)
• Totals (total consumption of halogenated
  solvents)
• Differences (expenses minus earnings)
• Average values (half hour averages)
• Related figures
• Relative figures (solvent use per product unit)
• Normalized figures (use of halogenated solvents
  over total use of solvents)
• Index figures (trends)
• Systematically derived indicators
• Complex methods for data aggregation

11
Indicators 1

• Non-dimensional indicators
• Efficiency, yield (product per input)
• Recycling quota
• Material-related indicators
• Cross rate between different materials
• Production-related indicators
• Material input per production unit
• Waste per production unit
• Plant-related indicators
• Energy consumption per hour
• Energy consumption per m²

12
Indicators 2

• Time-based indicators
• Waste per shift
• Water consumption per year
• Employee-based indicators
• Material consumption per employee (in offices)
• Water consumption per employee
• Emission-based indicators
• Actual emissions vs. threshold values

13
Definition of indicators

• Which figures reflect the targets (of my
  department) best?
• Which figures are best suited to indicate that
  these targets are not being met?
• How are critical deviations best measured?
• What is the best way of showing who is
  responsible for a critical deviation?
• For which indicators is information easily and
  inexpensively available?

Example Chicken efficiency

• Is the ratio of sold fried chicken to waste
  chicken
• Is the indicator for waste
• Is the most important indicator in the
  organization
• Does it make sense??

16
Difficulties in defining indicators

• Two or more different products in changing
  quantities
• Weigh, choose a stable baseline
• Changes in products or processes
• Indicators are only one tool and have to be
  complemented by more information
• Comparability between different companies
• Be careful you have to know the context
• Different data collection methods
• Standardize data collection

17
Definition of targets

• Targets could be
• Legal compliance
• Best available practices andtechnology
• Minimization of costs
• Continuous improvement

18
Targets should be

• Specific
• Measurable
• Achievable
• Realistic
• Time framed

19
Reports

• Frequency
• Standard reports
• Reports on deviation
• Reports on demand
• Strictly adapted to the receiver
• Use standardized structure
• Include reference values for comparisons
• Use graphics
