Allan Owens shows how to break down and simplify complex operations using a time-tested systems model.
Need out of the box thinking? Need a simple model to help you break down complexity? Think about the most complex computer application you’ve dealt with. Hard to understand? How about thinking of it as inputs/ throughputs/ outputs? Systems thinking is your powerful ally. Can system thinking help change professionals and other mass influence specialists?
The IPO model (short for “Inputs , Processing — or throughputs, outputs”) helps you organise complex systems. These systems include quickly understanding entire business units.
I have used the IPO model on many change projects. You can run workshops with employees in any business unit. Place three simple columns on a single page. They may tell you how complicated their business unit is. Even so, ask them about how their unit operates. Identify their responses as either an input, throughput or output.
Do all systems boil down to three things? Inputs, throughputs and outputs? If so, use this idea to distil complex systems and business operations into a one-page model.
Here’s an example IPO model for a future state procurement system:
All you need is a simple commentary in each of your three columns. Keep it high-level to avoid getting tangled in exceptional/ outlier transactions.
I suggest exploring a sandpit version of any system to start your work. Playing with a simple system is an easier start than relying on complex business processes, functional specifications or developer presentations. So play with a system or mock-up then map your one-pager.
You can use a single-page worksheet like this one for your IPO work:
Here’s a brief video explaining the above — I condense a lot into one minute:
The SIPOC model expands on the IPO model, adding supplier and customer engagements as bookends. Depending on the problem you are grappling with, you may have a preference for their model.
Hopefully you find the IPO model as useful as I do when confronted with complexity. Please feel free to comment, clap or learn more practical tools for addressing complexity, change or creative problem-solving.
