How to learn and improve from a tangled process - The spaghetti map

How can spaghetti diagrams be used within a work environment? Can we use them to help measure our processes? Can we use them to identify internal vs external touch points? Yes, we can!

So what can spaghetti diagrams apply to?

 

In a traditional environment, you may reach for this tool if you want to rearrange your office space. As you can see below, the spaghetti map highlights the movements done by the personnel, which shows how poor the office layout is designed. 

Non effective Office layout

The following office layout shows the actions taken by management to improve the office layout and reduce the movements, hence the waste.

IMPORTANT: The spaghetti map captures the movement of electronic data and can be applied just as effectively as in a physical space.

In the following example, you will see a complex chain of emails sent in an effort to resolve a customer stock demand.  The administrator was frustrated with the constant going forward and back to various departments for an answer, and finally escalated it to their Supervisor.

The number of emails had reached well over 100, and the administrator took the time to map out the flow of email information between each of the internal touch points, as well as the customer.

As you can see from the map, it makes the communication flow very visible.  It gives us the touch points which were touched the most number of times:

 

Inbound emails - Project Management Manager, Material Planner, Project Manager, Local Sales

Outbound emails - Local Sales, KAM, Project Manager

Non respondees - Director, VP, Planner

 

From this visibility, you can generate brainstorm questions:

 

  1. Is the Director and VP correct escalation path? 

  2. If Director and VP are escalation points, what is their process for reacting?

  3. How many times was the customer kept informed?  Who should have been responsible for updating the customer?

  4. Did all Planners need contacting?  Was there a clear Contacts list in place for knowing which Planner was to be contacted?

  5. Could have this been made simpler, with less people to contact?  Can additional approval levels be given to cut out some of these contacts?

  6. How much time was taken for each person to read the mail in case there was action required?  How can this be translated into cost of time lost?

The spaghetti diagram or map is a great tool, super visual! It  generates a lot of questions regarding the smooth flow of information. Either in a physical space or virtual environment, the use of this tool highlights waste.
