1. Lean Efficiency
in Agile
Muda, Mura, Muri

2. Muda (Waste)
Type 1 Muda wastes are those wastes that
are essential to producing a product or
running a business within current conditions.
Through improvement practices, these
wastes can eventually be eliminated.
Type 2 Muda wastes are those tasks that can
be eliminated almost immediately with
limited impact on the process.

3. 8 Types of Waste
Transportation Inventory Motion
Waiting (Wait of
time)
Overprocessing Overproduction Defects Skill Utilization

5. The Agile
Manifesto
Agile processes promote
sustainable development. The
sponsors, developers, and users
should be able to maintain a
constant pace indefinitely.

6. Mura (Irregularity)
 The lack of a smooth flow of work causing periods
of overstress or underutilization
 Huge fluctuations of work that are not controlled
for or adapted to properly
 Ways to Smooth the Workflow
 A Kanban flow system (Just in Time)
 Flexible employee skills, T-Shaped and generalizing
specialists
 Priority reassessment
 Elimination/reduction of arbitrary deadlines (Because you
want it now doesn’t mean you need it now)

7. Muri (Overburden)
When the rate of workflow causes stress to the
systems, machines, or people
As with Mura, this can be reduced by
smoothing the workflow
Prolonged periods of overburdened work
(smooth work at high volumes) would need to
be reduced or accommodated in order to
eliminate the overburden
Can result in increases of Muda Waste
