now I'm having troubles

I'm trying to convert the cloud for UDE 21 "Many quality problems are not revealed until  the integration phase." and I need some help.

Here's what I have so far.  You can see the conflict cloud is made up of 100, 130, 140, 110, and 120 - and I've made the border a little thicker.

 

It feels an awful lot better than it did an hour ago, but I can't see the forest anymore for the trees. 

I'd really appreciate a few more eyes over this before I continue.

Clarke,

450 should be "defects are easier and less expensive to fix when found early"

Hi Clarke - I've just come across this page and am both intrigued and mystified. Where do I start reading to find out what this picture is? Never seen anything about TOC before, particularly not pictures like this...
Thanks

It seems to me that there may be more than one cloud here. In order for integration to proceed smoothly, the interfaces must be well defined (good design) and the components must be tested prior to integration. Premature integration forces you to solve a bigger problem.

UDE 21. Many quality problems are not revealed until the integration phase.

A. (goal) Integration proceeds smoothly

B1. (need) Components are tested prior to integration

D1. Find defects before integration

C1. (need) Components are integrated as soon as possible

D1'. Integrate before components are adequately tested

B2. (need) Interfaces are well defined

D2. Define the interface before coding

C2. (need) Interfaces change as problem is better understood.

D2'. Define the interface 'on the fly'
