Controlling

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

Which indicators?


Aims of indicators

Comparison of the actual to the planned situation

Comparison of companiesComparison of variations

over a period of time


Development of a set of indicators

Mass balances and costs

Targets

Set of indicators

Targets: reduction of material losses,substitution, cost reduction,environmental improvement,data compression, presentation, analysis,control, decision making.


Types of indicatorsAbsolute 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


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


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


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??


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


Definition of targets

Targets could be:Legal complianceBest available practices and

technologyMinimization of costsContinuous improvement


Targets should be

Specific

Measurable

Achievable

Realistic

Time framed


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
