Time is valuable, and when it is gone, it is gone. Are you focusing on flow or just keeping yourself busy? How much has the red brick cancer spread in your processes? In this session we will talk about time. We will explore the differences between systems with high resource efficiency and systems focused on flow efficiency. We take a look at how to remove the red brick cancer in your processes. You will learn how to understand and improve the end to end flow in your system.

88. Bottlenecks
Every process has at least one
Created by Håkan Forss @hakanforss http://hakanforss.wordpress.com

89. Capacity = 6 Capacity = 4 Capacity = 6
Throughput = 4
You can’t go faster than your bottleneck
Created by Håkan Forss @hakanforss http://hakanforss.wordpress.com

90. As long as capacity in front of the bottleneck is equal to or grater
than the bottleneck you will go as fast as your bottleneck
You can’t go faster than your bottleneck
Capacity => 4 Capacity = 4 Capacity > 4
Throughput = 4
Created by Håkan Forss @hakanforss http://hakanforss.wordpress.com

91. Full use of a higher capacity in front of the bottleneck will make
lead time go up
You can’t go faster than your bottleneck
Capacity = 6 Capacity = 4 Capacity > 4
Throughput = 4
Created by Håkan Forss @hakanforss http://hakanforss.wordpress.com

92. As long as capacity is equal to or greater after the bottleneck you
will go as fast as your bottleneck
Higher capacity after the bottleneck than at the bottleneck will
not improve throughput over time
You can’t go faster than your bottleneck
Capacity => 4 Capacity = 4 Capacity >= 4
Throughput = 4

Reduce length or remove iterations
Use a mixed feature portfolio
Avoid swarming and ad-hoc
processes
