Knowledge Discovery Process?

Understanding
“If you can’t describe what you are doing as a process, you don’t know what you’re doing.”

Example: An Attemptto Map Process Steps
I can’t use a Kanban boardwith thirty-five columns...
...thirty-four
...and that’s only onework item type
Is There a Better Way?
Is There a Better Way?
Toyota’sProduct Development Systemis completely different from
the Toyota Production System
Hints: knowledge discovery, information arrival
Michael Kennedy
Knowledge Created
(not necessarily in this order)
• Exact production environment configuration (OS, Web server, DB server, third-party software, etc.)
• Key behaviour examples (acceptance criteria, executable specs, use cases, etc.)
• Integration (upgrade procedures, data migration, etc.)
• Code design and implementation
• Tests needed to support the code
• Actual behaviour of the integrated software with respect to non-functional requirements
• Results of usability tests and exploratory testing sessions
• Etc.

Discussion: Dominant Activities
• Consider one work item type delivered by your
organization (business unit, department, team)
• Think of its delivery process
• Can you identify the dominant activities for
discovery of new knowledge or information in
this process?
How Do We Get There?
Observations
Thinking
Recipes
Recipes
Start With Examples
Start With Examples
Don’t discuss abstract processes
Find several examples of recently delivered work items
of each type
Assumption: Work Item Types
Service Delivery
What?
To Whom?
Why?

expectations

Think of the peoplewho will come to the morning stand-ups
in front of the Kanban board
This is a Complex, Social Activity
People activate each other’s memories
People activate each other’s memories

This is a Complex, Social Activity
Facilitator:to help people recall the knowledge gained(not to retrace procedures and meetings)
One sticky note at a time
Watch Them Appear
• Turning points• Dominant Activities• Explicit Policies
Explicit Policies:• Definitions of Done• Definitions of Ready• Selection/Prioritization Policies• Input/Delivery Cadences• etc.
Timing
2-2½ hours: common1½ hours: rare3 hours: never
Observations
We involved only a few peopleto map out the process...
...and these people now dominateconversations during stand-ups

Reduce Board Churn
This new work itemdoesn’t quite fit the processwe’ve mapped out for it...
Complex systems: path-dependent
Dev, vertical line, test.Sigh... Silos again?
I prefer not to judge.This may actually be cool.

One step is missing:Visualize the workflow
(for each work item type identified by demand analysis)

A model of a systemaffects the system.How weird is that?

Provoke improvement,not inertia

Things on the Left, Things on the Right
• Knowledge discovery• Dominant activities• Collaboration• Models affect systems• “Linearized” flow• Process fits brain• Improvement• Need an acronym
• Assembly• Functional silos• Handoffs• Models reflect systems• Backflows• SharePoint• Inertia• VSM
