Fishbone is….
A diagramming tool for Cause and Effect / Root Cause Analysis
AKA - Ishikawa Diagram
Five Whys is used for…
Root cause analysis
Systems Thinking
- main concept (high level)
Is the process of seeing things as a system of interrelated actions/reactions that led to some result
Risk Management in Agile
- when is it done?
Every iteration, during every Agile meeting
What is a Risk Census?
An assessment of Risk that takes:
- Probability of Risk
- Impact to schedule
- Risk exposure in days (probability * size of loss in days)
Risk Adjusted Backlog
- does what to backlog items?
Lowers their priorities based on higher risk
What is one strategy to help identify project risks?
Premortem..
Imagine that a project has failed, and work backwards
Verification vs. Validation
Verify = Us: verify that what we built works
Validation = Customer: verify that what we built is what they wanted and works for them
Spike
- why is this done?
- name 2 aspects to it…
- name the 2 reasons why you would do it?
To experiment away a risk or uncertainty
- work is considered throw away
- timeboxed
1. Architecture - research/proove a certain aspect of the architecture
2. Risk - proves/disproves how risky something is
Agile KPIs
- What answers do they provide?
- Are we achieving our strategic and tactical goals?
2. Are our people performing at optimal levels?
Agile EVM
- when do you apply this?
Only at the iteration level
Scope Metrics
- name 4 types of these
- Approved iterations per release
- a manager would track planned vs. actual - User stories completed per iteration (burn down)
- Carried-over user stories
- are we trying to do too much, or did we not decompose well enough - Backlog size
Cumulative Flow diagram
- what do you look for?
When the bands thicken - this indicates bottlenecks between states
Cumulative Flow diagram
- what is type of Agile method is it most associated with
- what 3 things are in this diagram?
Kanban
- Planned features
- Work in progress
- Features completed
- Shows insight into Burnup (completed features), Cycle time, WIP, and Bottlenecks
Burn Rate
- how is this calculated
Teams combined cost x Iterations x Days
Quality metrics
- name 3 types of these
- Code testing coverage
- Defect rate &/or escaped defects per release
- Control limits
Control limits
- general concept…
Choose something to track, set upper and lower acceptable limits, choose unacceptable upper and lower limits.
Lean has a ‘Burndown’ type chart that is called
“Business ____ _____ Chart”
Value Delivered
