Obstacle Driven Development

OODA Evolution

OODA Model

OODA models are for strategy and tactics and model how people react to observations.

• Observe

• Orient

• Decide (Hypothesis)

• Act (Test)

OODA Model

Explains how to react to Unfolding Circumstances and Outside Information.

• Also for commercial operations and learning operations

• Favours agility over raw power in dealing with obstacles

Orient Stage

Inside of the Orient stage are a smaller model of the interactions between:

• Cultural Traditions

• Genetic Heritage

• New Information

• Analysis and Synthesis

• Previous Experiences

Obstacle Driven Development Software Model

Each stage has tests created prior to solutions as with a scientific method.

• Tests created provide verification

• Solutions created according to tests provide validation

Obstacle Driven Development Software Model

Based on a combination of Test Driven Development and V-models.

• V & inverted V-models for development of stages

• Tests are created first for each stage

Obstacle Driven Development Software Model

Relative height of the model indicates the abstraction level.

• Gives a layered architecture to models

• We integrate or decompose to complete each stage

• Product and function are highest and lowest

Similarities

14/09/2017 ©odd.enterprises 8

Similarities were identified between the OODA model and Obstacle Driven Development (software model shown).

Similarities

14/09/2017 ©odd.enterprises 9

• Observe ≈ Analysis

• Orient ≈ Behaviours

• Coding ≈ Decide

• Act ≈ Application

ODD Software Model

Each stage of ODD drives development of the next through creation of tests for the obstacles.

• Each stage creates tests for the next

• Each stages solves tests from the previous

ODD Software Model

Obstacle Driven Development models include checkpoints.

These are:

• Requirements

• Documents

• Software

• Product

ODD Engineering Model

Obstacle Driven Development was originally an engineering method.

• Problems with the model solved through studying military and sports strategy

• Adapted to other fields since

ODD OODA Model

Applying Observe, Orient, Decide and Act stages to an M-model.

• Fully testable model useful to develop strategy and training

• Checkpoints at the end of each stage

OODPAA Model

Adding Stages of Prepare and Assemble gives a new level of Strategic organisation.

• Prepare is logistics of supplies and equipment

• Assemble is locating in the correct place

OODA.SE Model

M-models repeat for continuous improvement as demonstrated by the diamond model.

• Each stage is linked through creating and solving tests

• Act and Result join with Observe and Requirements

• Act and Observe linked through Affect and Assess

Combining the Models

14/09/2017 ©odd.enterprises 16

Combining the models was a simple process with the similarities between them. Feedback and other features were added to the ODD OODA model.

Combined ODD OODA Model

Combining the ODD and OODA models leads to this model.

• Decision block is included before Act

• All feedback and feedforwards paths are included

• Adaptions to the Orient stage

14/09/2017 ©odd.enterprises 17

Combined ODD OODA Model

• Observe now contains New Information and Analysis

• Orient now contains Previous Experience and Tradition + Heritage

14/09/2017 ©odd.enterprises 18

Combined ODD OODPAA Model

Adding the Supply and Assemble stages gives the model a further strategic level.

• Supply and Assemble feedback to Observe

• Preparing and Assembling is essential to success

14/09/2017 ©odd.enterprises 19

Generic Model

Examining similarities between ODD and OODA led to a generic model being created.

• Each stage is a combination of ODD and OODA

• Other models have been created from this model

PDCA Model

PCDA is a business method for control and continual improvement of processes and products.

• Creates a culture of problem solvers and critical thinkers

• Also called Plan, Do, Study, Act

• Another version adds Observe to make OPDCA

14/09/2017 ©odd.enterprises 21

APDA Model

Combining PCDA with ODD gives an APDA model.

• Analysis stage begins the method

• Check is implicit between stages

• Full verification and validation between stages
