Efficiency Can Kill Your Startup

Optimising a part of a system often results in sub-optimising the system as a whole

There is a real danger in relentlessly seeking cost-savings and efficiency in your company. The problem is that often as we optimise part of a system by making it more efficient we sub-optimise the system as a whole. This idea is explained as the Doorman Fallacy described by Rory Sutherland:

The ‘doorman fallacy’, as I call it, is what happens when your strategy becomes synonymous with cost-saving and efficiency; first you define a hotel doorman’s role as ‘opening the door’, then you replace his role with an automatic door-opening mechanism.

The problem arises because opening the door is only the notional role of a doorman; his other, less definable sources of value lie in a multiplicity of other functions, in addition to door-opening: taxi-hailing, security, vagrant discouragement, customer recognition, as well as in signalling the status of the hotel. The doorman may actually increase what you can charge for a night’s stay in your hotel.

When every function of a business is looked at from the same narrow economic standpoint, the same game is applied endlessly. Define something narrowly, automate or streamline it — or remove it entirely — then regard the savings as profit.

Excerpt from: Alchemy: The Surprising Power of Ideas That Don’t Make Sense by Rory Sutherland

As stated in this excerpt efficiency is a very narrow economic dimension. It is defined by the amount of resources needed to execute your process. Low efficiency means that you require a comparatively high amount of resources to execute your process (and vice versa). It does not look at the result of the process, which we define as effectiveness:

Effectiveness is the capability of producing a desired result or the ability to produce desired output. When something is deemed effective, it means it has an intended or expected outcome, or produces a deep, vivid impression. (Source: Wikipedia, where else :-p)

The system that describes the relationship between efficiency and effectiveness is called productivity. The Doorman fallacy describes a system where Efficiency increases but as a result Effectiveness goes down. This results in a decrease in productivity. In this system of productivity there are 4 scenario’s:

  • Scenario 1:
    Low Efficiency + Low Effectiveness = Declining business activity
  • Scenario 2:
    Low Efficiency + High Effectiveness = Unprofitable growth
  • Scenario 3:
    High Efficiency + Low Effectiveness = Unsustainable profitability (Doorman Fallacy)
  • Scenario 4:
    High Efficiency + High Effectiveness = Sustainable profitability

As a founder you should always focus on Effectiveness first. This usually means that a startup ends up in scenario 2. Which is fine as long as there are people willing to finance that growth. There always comes a point where a startup has to start optimising their process and look at the efficiency of the business to become profitable. This is where the Doorman fallacy becomes a real risk for your business. If you don’t fully understand why your company is effective you might loose what made you successful in the first place.
