Learning Activities

Learning Activity 1
You are in A&E and have completed a process map and found that the bottleneck (constraint) is at the start of the process in the que to clerk in to A&E. Can you suggest any actions you could take to follow the five step model?

Learning Activity 2
Complete a process map of your own department, where are the bottlenecks? Look more closely at the bottleneck and examine the times with a group of patients …
When processing mapping find out
*How many patients are waiting
*The length of time for the procedure at the bottleneck
*The capacity of staff in the department (the skills) to use a piece of equipment or provide a specific service;

Learning Activity 3
Find out how many patients can be seen with the Radiographer for a woman to have a mammogram
Two mammogram machines multiplied by 480 minutes (8 hours) of session time, amounts to 960 minutes (16 hours) of capacity each day as long as there are two radiographers and two assistant radiographers each day. (In the real world Both radiographers will have to attend the MDT and write up reports and will be available 38 months of the year working 5 days a week, but this is not factored in our simple calculation).

Now that you have this information, capacity can be converted into number of patients each day. So if it takes 2o minutes for a mammogram then how many patients will be seen during the day?


Learning Outcomes : By the end of this learning unit you will be able to

  1. Outline the 5 steps of a theory of constraints
  2. Explore how to work out capacity, demand and activity
  3. Review the Case Study by Halla Zaitoun to understand the application of capacity demand and activity concepts in paediatric dentistry
