Improving the performance of businesses is often like being set loose in a commercial kitchen without a recipe. Random ingredients, absence of some staples, disaffected staff, erratic processes, and severe cost pressures, but still being expected to produce an experience people are prepared to pay for.

Not easy

However, every time I look back on a project, the common factor that has made the most difference is not what you would expect.

It is not the financials, or the marketing plan, or how well the sales force performed, it is more basic than all that, and enables all those things:

Flow.

Simple word, and an idea at the core of all performance improvement.

The concept of flow emerged from the work done to improve manufacturing processes by W. Edwards Deeming, Joseph Juran, and others, and was first widely implemented and documented by Toyota, then spread around the world as ‘Lean thinking’ and the ‘Toyota Production System’.

At the core of Lean is Flow, and at the core of any improvement in any process, physical or otherwise,  in any context, is flow.

The basic confusion is between being busy, and being productive. Jumping up and down in one spot may be  busy, but it is hardly productive unless you are killing ants.

Optimising flow in manufacturing operations requires the configuration of all the lines such that work passes unobstructed from job centre to job centre through to completion. The faster and more uninterrupted the flow, the higher the output.

Flow optimisation always requires the counter intuitive decision to leave unused capacity at points in the process, to avoid building Work in progress inventory, which act as ‘rapids’ in the flow metaphor. It usually feels wrong to leave available capacity unused, but the slowest work centre will be the limiting factor for  the whole process, and to keep the flow steady, the flow rate is limited by that slowest point. In addition, shit always happens, something breaks, an item spec ‘wanders, ingredient fails to come in as required, so there is always downtime of some sort. This means that  some spare capacity in the system is a requirement for  the flow to be matched to demand, or ‘Pull’ in Lean parlance.

A key component of flow is the orderly release of work into the process. A schedule is written based on priority and optimal flow, and is then executed without change. Queue jumping, to meet unscheduled customer expectations, is a common distraction from the plan that multiplies, disrupts everything, and often results in total turmoil in the flow. It is deadly to process optimisation.

These days, not as much manufacturing is done, after all many of us are told we are now knowledge workers.

Exactly the same principals apply. While it may be harder to see because there is no physical product moving down a production line, the thought process is identical.

The trouble with these non physical tasks, is that they come at us from every direction, often with little warning and lead time, and with ambiguous importance and priority. Unscheduled demands on our time.

How do you sort through the mess to optimise your productivity?

A now standard method is the scaling of Importance and urgency into quadrants. When analysing how our time is spent, most of us find that too much is spent in the not important/urgent quadrant, when we should be focusing on the important items, urgent or otherwise. It is almost always the important/not urgent tasks that get shuffled aside, and it is these items that have the greatest long term impact on the performance of an enterprise.

An alternative means to allocate time is on an ‘Impact/Effort’ continuum. Tasks that are high impact, low effort are the quick wins so beloved of consultants, by contrast, high effort, low impact tasks are just thankless tasks, and not worth doing.

Everyone is in charge of managing their time to some extent, the further away you are from a time driven physical process, the greater the amount if discretion you will have. It behoves you to work the tasks in front of you in order of priority. Responding to that email may seem important, after all it has come in, the ‘new email bleep’ (Pavlov would love this one were he still alive) has sounded, there is a sense of urgency generated, but in 99% of cases, what does it really matter of the email goes unopened.

In everything you do, consider the impact and benefits of optimising Flow.
