• Defines value from the customer’s perspective • All of the actions and tasks, both value added and non-value added,

required to bring an item (an idea, information, product or service) from its inception through delivery. – These include actions to process information from the customer

and actions to transform the product on its way to the customer. • Value streams vary in scope: reach beyond the enterprise to single

process size • https://www.youtube.com/watch?v=IbGPqmdBJp0

• Value Stream Mapping • Kaizen Teams • Defect Prevention / Mistake Proofing • Variation Reduction / Six Sigma • 5s/Workplace Organization • Visual Factory Management • Standardized Work / Methods Analysis • Cellular / Flow Manufacturing, Office and Administration • Constraints Management • Generic Pull Systems • Part Pull / Kanban Systems • Set Up Reduction • Total Productive Maintenance

Ultimately Results in a Change in Human Behavior

Core Lean Tools and Techniques

Products, information, or services flow through a value stream – In manufacturing or distribution, materials are what flow – In health services, patients are what flow

– In office areas, information is what flows • In service areas, external customer needs flow through

the value stream • In administration, internal customer needs flow through

the value stream • In many cases, the item flowing in service or

administration is a document, an order, or a request

What Flows Through the Value Stream?

Purpose of Value Stream Mapping & Analysis

• Develop a common understanding of the current process – The relationship of process steps – A true picture of the process

• Create a baseline to measure improvements against • Define a vision of the future process • Establish common leadership objectives • Identify opportunities for improvement • Design an implementation plan for improvements

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

Value of a Value Stream Map

• The Value Stream Map provides visibility of the entire process – The process may cross functional boundaries – Without the map, you may focus on the wrong

areas to try to improve – Sub-optimization may result

What is Value Stream Mapping? • Value stream mapping is a process-mapping method that

enables your organization to:

• Current State Map: Visual representation of existing operations (information and product flows) – Identify the largest sources of waste (non-value added activity) in the

value stream

• Future State Map: Drawing of Lean flow (vision) – Develop implementation plan for Lean activities

More on VSM Previous Page Next Page

Map the Process • Makes work visible

– Visibility improves communication and understanding

• Identifies Improvement Opportunities – Eliminate the non-value added steps – Reduce wasted resources

• Diagnostics – Determine the cause of a problem or

condition. • Training and communication

Opportunities to Enhance Value Stream Mapping

• Classic Value stream mapping can overlook environmental considerations: – Raw materials used vs. needed in products and processes – Pollution & other environmental wastes in the value stream – Flows of information to environmental regulatory agencies

• Making some simple adjustments to your value stream map can help you explicitly address pollution and natural resource wastes: – Improving cost reduction opportunities – Saving additional time – Improving the health and safety of the workplace

Milestone/Date

Charter Owner:

Setting up and “Scoping” a Lean Value Stream Mapping Project

• Charter and other Pre-work • Roles for the VSM Team

– Executive Sponsor – Process Owner – Lean Coach (Facilitator) – Workshop Participants

Role of the Executive Sponsor • Owns the Charter! • Addresses necessary cross-functional involvement • Ensures appropriate participating in the workshop (make sure the

subject matter experts are freed up full-time for the 3-day event, and part-time to implement Action Items)

• Serves as a proactive roadblock buster for the project • Presents project status to leadership • Participates in:

– Scoping – Workshop Kick-off – Leadership Panel – Project Reviews (30/60/90 day follow-up audits)

Role of the Process Owner • Owns the Setup Tasks and Action Plan!

• Leads VSM project from pre-scoping through implementation

• Ensures action item pre-work is complete for scoping, workshop, and reviews

• During VSM event, takes over ownership during Action Item assignments

• Responsible for project meeting scheduling, preparation, and minutes

• Documents the implementation plan after the workshop and schedules 30-, 60-, and 90-day reviews

• Drives implementation plan activities for completion of the project

• Provides updates to Sponsor

• Monitors post-workshop process performance seeking opportunities to continuously improve and standardize work

Role of Lean Coach • Coaches Process Owner in the application of lean principles and

tools • Leads project scoping while mentoring Process Owner • Prepares Process Owner for workshop • Trains team and facilitates most of the workshop activities,

sometimes with the Process Owner – Transfers lean skills to leaders and participants

• Helps participants track and measure future state improvements • Serves as the subject matter expert in driving and institutionalizing

lean throughout the organization

Role of Workshop Participants

• Participate in the 3-day event as Subject Matter Expert (SME) (full-time); be the change agent for implementing Action Items (part-time)

• Representative staff as SME from each area that touches the process

• Staff who are well respected within their area • Group of less than 15 is ideal

Value Stream Process Steps

1. Prepare

2. Gather Data & Develop Current State

3. Develop Future State & Action Plan

4. Execute to Plan

5. Align

Value Stream Process Step 1 - Prepare

• Gather Preparatory Information – Document the Case for Change – Define the Scope (start and end of process) – Identify the Requirements – Review/establish Measurements

• Set Logistics for Event – Participants – Location – Materials – Meals/Refreshments – Etc.

Value Stream Process Step 2 - Gather Data (Develop Current State)

• Observe and gather data – Walk the value stream - see the actual work place – Follow and make notes about “item” and information flow – Gather data for each step in the flow

• Trigger/done actual lead time output • Actual cycle time on time delivery staffing • Defect rate batch sizes overtime • Quality variations work in process

• Map the flow of items • Map the flow of information • Add data and issues

Value Stream Process

Step 3 – Future State & Action Plans

• Discuss the ideal state

• Develop the future state map

• Develop action plans & cadence tracking – Build draft time line for implementation

• Communication & training as required

Value Stream Process

Step 4 – Execute to Plan

• Implement improvements – Conduct Workshops, events, projects, bursts per implementation

plan

• Achieve value stream objectives

• Create an environment of continuous improvement

Value Stream Process Step 5 – Align

• Conduct Value Stream Alignment Meeting – Periodic basis (based on action plan schedule)

Agenda – Review event implementations & results – Review impact to value stream metrics (individual events and

overall) – Review next quarter events – Review changes in business environment – Communicate results – Update value stream as required – Update implementation plan as required – Address resistance and sustainment issues

Value Stream Process Additional Tips for Success

• Capture as you go: – Issues – Acronyms / terminology – Parking Lot issues – Action items

• Establish a time each day for Leadership to visit the workshop – Status update – Ask questions – Barrier busting

• Capture at the end of each day: – Lessons Learned – Agenda for next day

• Champion summarization for Leadership at end of each day (email): – Team accomplishments for the day – Agenda for next day

Remember

• The Value Stream Map is a plan – Helps you get from the current state to the future state – A good plan creates the opportunity for success – even

if you can’t see the path to get there

Types of Lean Events

5S Kaizen Project Do-it Burst

Value Stream

Kaizen event

• 3-5 days • Scope significant - can be cross-functional • 6-12 people or more • Quick impact

– 80% of improvements implemented during event – 20% of improvements implemented within 30 days

• Implementation per prior management agreement

Typical Kaizen Schedule

• Day 1 – Training • Day 2 – Analyze Current Process • Day 3 – Define New Process • Day 4 – Test & Finalize New Process • Day 5 – Report Out & Celebrate

Some of these “days” may be reduced to “hours,” depending on the scope of the effort

Burst Event

• Short duration (2-4 hours) • Minimal scope/Single issue • 4-6 people • Quick impact • Intended for relatively simple tasks

Do-It

• Very short duration (1-2 hours) • Simple scope/Single task • 1-3 people • Immediate impact • No decisions or management intervention

required

Project

• Long duration (3-12 months) • Complex scope • Multiple departments/functions • Long-term impact

5S

• Typically a 3-5 day event • Provides workplace organization • 6-12 people • Provides framework for monitoring &

continuous improvement

How do we know which event type to use?

• Type of activity • Scope of process/task • Resources required

Don’t worry about fitting the event type into a specific category

Keys to Successful Events

• Have the right people in the room • Empower the team to make immediate changes to the process • Full participation from all team members • Attack process, not people • Agree on measures and how they will be collected • Review action plan frequently for progress

Thank you!!!
