Agility Triad Constraints
Control
Its aspects
Monitoring plan execution and outcomes
Taking corrective actions
Empirical process
Plan-Do-Check-Act/Adjust (PDCA) cycle
Yields fast learning cycles
Executed as minimum viable product (MVP) cycles
Defers decisions until the last responsible moments (LRM)
Technical scope management
Speed
Diminishing
Lead Time and Cycle Time
Managing technical scope
Shrinking work item backlogs/queues and queue item sizes (batch sizes) processed (Little's Law)
Defining and building solution iteratively and incrementally
Pursuing quality through technical excellence
Improving software development technical practices and techniques
Technical contributors committing to ongoing professional development
Minimizing waste
Seven sources of waste (TIMWOOD) by Lean
Waiting
Idle time caused y mismanaged dependencies
Overproduction
Developing rarely used or unused solution functionality
Increasing work in progress (WIP)
Motion
Task switching
Repeatedly doing the same thing (manual processes)
Over-processing
No-value-adding work (e.g. "gold plating")
Inventory
Rarely used or unused solution functionality
Work not released or not used by customers
Defects
Software bugs
Transport
Coordinating and gaining approval through documentation
Formal reviews and coordination boards
Handoffs at different phases of development
Lack of direct collaboration
Flexibility
Based on the degree to which
A
higher-performing team
is formed
Meaningful purpose
Specific goal(s)
Clear and flexible working approach
Adequate level of complementary skills
Sense of mutual accountability
Small enough number of members
Decision-making is decentralized/distributed across organizational levels
Project planning is adaptive
Optimal solution
approaches are driven by collaboration
Achieved through
Fast learning cycles
Helps to cope with complexity
