PDC+++ Module 2 Class 10 Design Techniques II

Class 2.10 of the PDC+++Which design techniques do I have at my disposal & how do I know when to apply them? PART 2 of 2There are a great number of design methods & it is important to choose those that are best suited to your particular circumstances & objectives.

In this class we look at some of those methods & talk about the criteria to take into account for their use.

Fibonacci Series:

1, 1, 2, 3, 5, 8, 13, 21, 34 , etc. ...

The red one is the aural spiral

A harmonious assembly of species around a central element (plant or animal)

This assembly acts to assist health, aid our work in management, or buffer adverse environmental effects

As a general rule do not plant species of the same family together, as they are affected by the same pests.

Physical ComplementarityPhysical Complementarity

• Some plants like sunshine and other a bit of shadow in Summer.

Lettuce & carrots can be planted with some plants that give them some shadow.

• There are plants with deep roots and others with more superficial ones, these can be combined. Eg. TOMATOES & LETTUCES.

• Plants with different maturation times can also be combined. Eg. CARROTS AND RADISHES.

• Some insects recognize plants by their silhouette or odor and these can be camouflaged by other plants

Apply Self-Regulation&

Accept Feedback

Which factors worked& did NOT work in all resistance

movementsto date?




Holacracy = self-organized teams (circles) structured in a holarchy (nested hierarchy) of different levels.

Each circle defines & assigns roles needed to achieve aims

Different levels are connected by a double-link

They look for a “workable” decision

at any one time

Dynamic steering = feedback and continuous self-regulation, any decision can be revised at any time
