Our first go at CATWOE and an SSM Root Definition

Hello Systems Thinkers,

Let’s go CATWOE

So, we now have a top level Root Definition for our canteen “system”.  It’s taken us several weeks to reach this point, each week working through different segments of the CATWOE mnemonic.  If you remember, this is the 3rd stage in Soft Systems Methodology.  It is essentially like a statement of purpose for the system that takes into account who the stakeholders are, the perspective/s the purpose is viewed from, and environmental constraints.

Unlike the alphabet, we began with a W…

We started the process off by identifying all of the important stakeholders.  We then considered the various Worldviews (W) they might have. There we quite a few, ranging from the purpose of the canteen being to provide sustenance, family friendly employment, to a source of profit for the Local Authority (although we don’t actually know whether it makes a profit or not).

…and then T, E, C, A and O…..

We continued by identifying a variety of Transformations (T) that are at play. These are essential the functions that it performs.  We identified top and lower level Ts, although it’s only the top level ones we’ve included in the Root Definition below. We’ll look at others when we create root definitions for sub-systems.  We considered what Environmental (E) constraints were at play.  These included things like having to comply to food hygiene legislation and being bounded by the physical space available in the building.  Finally, we worked out whether the various stakeholders were Customers (C), Actors (A), or Owners (O) within the system.

…before we could draft our Root Definition

I really need to write much more about this, and also take you through the elements of CATWOE and what stakeholders and factors we identified against each.  I’m just too short on time this month.  It’s important, so I promise I will catch up properly and do it.  For now, here is the Root Definition we’ve come up with:

“A system owned by the Local Authority and operated by their employees, to provide an environment that supports relaxation and social interaction and provides nutritional food at lunchtimes that satisfies the need for affordable hot and cold food and drinks and facilities to heat and eat home prepared food, which recognises appropriate legal requirements within the existing canteen space within the building.”

The W changes everything

There, that is quite a mouthful  It covers a lot of ground though.  We felt we are going to need to revisit it next week to see if we’ve omitted anything.  Also, this root definition is created from a particular Worldview (W), that being that the general purpose of the canteen is to provide sustenance and a place for workers to relax.  If we took another W, such as it existing to fulfil a duty of care the Local Authority has, or as a vehicle to make profit, the Root Definition might end up being quite different.  We’ll play around with that and experiment next week.

As does the boundary

You might also notice that we’ve omitted the “Meals on Wheels” service that operates from the facility, and also not mentioned the new competition the canteen is now facing from the higher end food outlet that has opened across the road.  We decided to make our lives easier at this first pass and draw our “boundary” in fairly tight.  Indeed, we had a discussion about where we were drawing our boundary, and also opted to leave food suppliers outside of it.  We discussed the potential risks and impacts of doing so, but as the items the canteen buys in a commodities and readily available, we decided it safe to do so.

We’re not done with Root Definitions, but I’m done with this week.  I wish you an excellent weekend.
