2010 – Kanban “blue book”

2014 – Kanban from the Inside

What is Kanban?

Kanban – Japanese term for “signboard” or

“Billboard” that indicates “available capacity

(to work)” or a visual cue to begin work.

Kanban System - A visual system for managing

work moving through a process – the “value

stream”

The Kanban Method

Digite, Inc.

7

Change Management Principles

1. Start with what you do now

Understanding current processes, as actually practiced

Respecting existing roles, responsibilities & job titles

2. Gain agreement to pursue improvement

through evolutionary change

3. Encourage acts of leadership at all levels

Kanban Method uses…

… uses kanban boards to visualize invisible work,

workflow & business risks together with kanban

systems which limit work-in-progress

Kanban Method delivers…

… faster, more predictable service delivery and an

adaptive capability that enables you to respond

effectively to changes in customer demand or your

business environment

Digite, Inc.

So Why Should you Care?

Kanban will Help you Get Lean!

Visualize and Map your Value Stream

Continuous Flow

Incremental Change, Continuous Improvement

Be Data Driven

What is Lean?

Preserve and deliver value

Eliminate waste

Any resources not being used to drive value are being

wasted

Continuously reflect and improve

The Kanban Method

General Practices

1. Visualize (with a kanban board 看板)

2. Limit work-in-progress (with kanbanかんばん)

3. Manage flow

4. Make policies explicit

5. Implement feedback loops

6. Improve collaboratively, evolve experimentally

(using models & the scientific method)

• Defining constraints helps Flow

• Communicates available capacity to the team

and stakeholders

A Kanban System consists of a

quantity of “kanban” (かんばん)

signal cards in circulation

Overburdening is a common Problem

Multi-tasking is a commonly expected performance measure in most team. We are expected to be able to handle multiple things at the same time.

Digite, Inc.

26

Multitasking is Bad! Kanban helps you Reduce it

“It’s unequivocally the case that workers who are doing multiple things at one time are

doing them poorly,” said Clifford Nass, director of the Communication Between Humans

and Interactive Media Lab at Stanford University.

“The human brain just really isn’t built to switch rapidly from one task to another.

Workers who constantly multitask are hurting their ability to get work done, even when

they are not multitasking. People become much more distracted, can’t manage their

memory very well.”

Companies that demand multitasking may be damaging productivity. “It would be a total

tragedy if when we have so much potential to make the work force more intelligent, we

are actually making the work force dumber,” Nass said. “Companies that are demanding

that workers multitask might not only be hurting their productivity, but may be making the

workforce worse thinkers.”

*Ruth Mantell, Wall Street Journal Market Watch, July 12, 2011, “Multitasking: More

work, less productivity”Digite, Inc.

Multi-tasking is one reason

we have too much WIP

Stop Multitasking

WIP Limits benefits

Controls Multi-tasking

Signal that capacity is available;

Can be by person, by workflow, by work item

type, or by total number of items in progress;

Promote finishing & quality;

Provoke important discussions;

Risk Dimensions

(also called Class of Service)

• “What will happen if you

don’t finish the work item on

time” (Cost of Delay)

• A set of policies that apply

to a type of work.

• Can be indicated with colors,

shapes, stickers, etc.

• Can affect prioritization

Expedite – critical and immediate cost of delay; can exceed other kanban limit (bumps other work)

Fixed date – cost of delay goes up significantly after deadline; Start early enough & dynamically prioritize to insure on-time delivery

Standard - cost of delay is shallow but accelerates before leveling out; provide a reasonable lead-time expectation

Intangible – cost of delay may be significant but is not incurred until much later; important but not urgent

“Scrum vs. Kanban”

Is it an emotional thing?

So, how well is Scrum working for you?

It is working just fine for me!

I think it is working fine – but I’d like

to know how we can get better..

I need serious and immediate help to

improve!!

Digite, Inc.

62

Some Challenges in Scrum

Estimation Challenges

Missed Scope/ Deadlines; Stories leak out

Software is not necessarily working or tested

Overwhelming focus on “rituals”

how to calculate the right velocity,

what % of time to allocate to surprises,

estimation inaccuracies and other such problems.

The Challenge of Batch Sizes

Disruptive Role-changes and Org Changes

Digite, Inc.

63

Should you be applying Kanban to Scrum?

If everything is going well – and you are delivering

software to your customer as per their expectations –

perhaps there is no need to!

If you know – or have niggling doubts – that you could

be doing better, then by all means, look at Kanban!

Even if you don’t and you’d like to explore Kanban,

that’s a great reason as well.

Digite, Inc.

64



Continue with your current Scrum processes and rituals, roles and titles

Continue to do Sprints and Releases, and use Scrum metrics and measures

Visualize your Dev team’s process more granularly

Agree to Improve Incrementally

Allow acts of leadership at all levels

Digite, Inc.

65

Implementing Kanban in a Scrum

environment

Short Term: Start with what you have

Start with all the Standard Practices of Kanban

Implement WIP Limits and Manage Flow

Medium Term: Evaluate Improvement Opportunities

Evaluate/ Implement 2-Phase Commitment

Tweak WIP Limits and Process Steps

Long Term:

Consider moving to faster/ on-demand replenishment

Use models such as Risk Assessment and Monte Carlo Simulation for better Demand Management and Delivery Forecasting

Digite, Inc.

66

Scrumban or Kanban? (What’s in a Name?)

Scrum + Kanban =

Scrum or Scrumban

or Kanban – YOUR

Choice!

The Kanban Method provides a number of

tools and techniques to boost the

performance of Scrum teams.Digite, Inc.

67

Scrum and (not vs.) Kanban

Kanban does not compete with

Scrum.

Kanban complements and

supplements Scrum!
