“The input-output process depends on productive and allocative efficiency, whereas the output-output process relates to effectiveness” – Dr John Cox – Transport Engineer and Economist
What does this mean?
What is the difference between efficiency and effectiveness?
- Efficiency: This is about doing things in a resourceful manner. It involves maximising outputs from given inputs or minimising the resources needed for a desired level of output. Doing things right.
- Effectiveness: On the flip side, effectiveness is about doing the right things that lead directly to achieving desired goals. It’s outcome-focused.
An example in everyday life is when we often choose tasks we like doing, rather than the important tasks we should be doing. Thus, we optimise HOW we do a task or tasks, instead of WHAT we should be doing to make progress.
Sadly, too often we hear politicians talk about efficiency. But, what about effectiveness?
How often do politicians do the right things to get the best outcome for the country?
I can remember an Australian Government claiming they were efficient as they had passed a record amount of legislation, much of which it could be argued, made doing business far less efficient due to regulatory constraints (i.e red and green tape) thereby reducing business effectiveness (i.e. profitability and customer service).
An example of a business that was efficient but not effective.
Tigerair was a cheap Australian airline that offered very cheap fares, had high aircraft utilisation, minimal on board services and tight cost control. On paper it was extremely efficient. Although the COVID pandemic had an impact, it failed because of poor reliability, high customer dissatisfaction that damaged the brand and 2011 grounding due to safety concerns. It was efficient but not effective as it delivered a service customers were not willing to accept. Tiger closed in 2020.
Can businesses be both efficient and effective?
Aldi, the German supermarket chain, which opened Australia in 2001 shook the retail landscape. Aldi’s streamlined product lines, limited staff, and simple store layouts minimised operational costs, allowing for competitive pricing. Their efficiency extended to supply chain management, with a strong emphasis on local sourcing and lean inventory practices. This focus on doing things economically has allowed them to offer lower prices, attracting a broad customer base and claiming today 10% of the Australian grocery market.
What are the lessons here?
The most important message is to understand the difference between efficiency and effectiveness. We must ensure that we do the things that improve the effectiveness and profitability of the business. Remember there is a vast difference between measuring efficiency and effectiveness!
Measuring effectiveness allows us to determine whether an investment or action has been worthwhile. There is nothing more stupid as to do something more efficiently that should not be done in the first place!
