Process For Continuous Improvement Process For Continuous Improvement

What is Six Sigma?

•6 Sigma provides a process based approachto continuous improvement.

•It is independent of the measurement involved

•can be used to improve any business process

Enabler for Cultural Change

What is Six Sigma?

•To be successful, 6 Sigma requires a radical change in the way an organization works.

•Business Leadership and 6 Sigma can together transform a company

Fundamentally Different Approach

Enabler for Change

Before6 Sigma:

1) Inspect the product2) List the symptoms perceived as being the cause of the problem3) Initiate action to mitigate / eliminate the symptoms

With6 Sigma :

1) Measure the process output & analyze the data2) Discover quantitative relationships between the output & in-process variables3) Develop & implement control plan

Quality Starts with the Customer

What are CTQs

•Fast Renewal Quotes •Renewal quote in customer’s hands within eight working hours

•Accurate Invoices •Customer data on invoice matches current coverage document, field by field

CTQs are specific and measurable requirements taken directly from our customers — Not what we think our

customers want or need

Customer Needs(What they say)

CTQs(What they mean)

Page 15: Rapa 2004 oct_six_sigma_in_insurance

15 /GE /

June 7, 2004

Quality Starts with the Customer

Improve our products, processes and services from our customers’ standpoint - drives metrics

Provide a common language regarding customer requirements throughout the company

Create a differentiation in the marketplace

Why CTQs are important

Page 16: Rapa 2004 oct_six_sigma_in_insurance

16 /GE /

June 7, 2004

How we use them

CTQs are gathered directly from customers:

- Customer meetings- Surveys- Scorecards, dashboards

CTQs are the input of every cockpit and drive the performance of those cockpit metrics

CTQs are at the front end of every Six Sigma project

CTQs are concise, clearly defined, and easily understandable

Quality Starts with the Customer

Business Case / Business Y: Big Y – Find to Issue. Priorities – Customer Relationships, Electronic Data Capture

Problem Statement: Critical Illness does not have a customer set up process - leading to lack of confidence in our ability to effectively manage our strategic customer relationships based on agreed-to processes. As we target significant growth in this business, we need a process to effectively manage our customer relationships and obtain marketing data about these customers. We need a cohesive customer set up strategy that facilitates data sharing among functions….reducing the amount of time that is spent fighting fires due to lack of coordination.

Goal Statement: Establish a Customer Set up Process that optimizes how we work with our clients. 1. Reduce Future Customer Pain … Enhance Client Experience. 2. Ensure Client & ERC Both Understand Data Needs Through Relationship and all parties have the required data to monitor the account effectively. 3. Ensure all functional areas and parties understand the intent of treaty and the relationship

Project Scope:

Start: when customer (cedent) indicates acceptance of a quote. Stop: once a document of understanding has been presented and acknowledged by customer (cedent)Includes: GLH A&H U.S. Critical Illness, Process and documentation for customer set up, Definition of customer set up elements as they relate to the treaty, A “service agreement” between the customer and GE ERC, Changes to existing agreementsExcludes: Establishing a Customer Database / CRM system, Consistency of reserving, financial reporting, etc. , Actual execution of the treaty, Other A&H businesses

Project Team:• Project Leader…Champion…Sponsor… Mentor…Team Members

Stakeholder(s):• External Customers – Critical Illness Customers and Prospects• Internal Customers – All Functions impacted by customer set up process• Shareholders - US A&H senior management

Project CTQs

-Level 1: Creation of Service Agreement / Communication Plan for Relationship

-Level 2: Accurate, Timely and Complete

-Level 3: Data in Service Agreement = Agreed to Terms and Relationship Parameters, 100% of ‘Fields’ in Service Agreement are Complete, Services Agreement is Signed Prior to First Sale/Deal, Communication Plan is Developed Prior to First Sale/Deal, 100% of Communication Plan has been completed

A defect is any event that does not meet the specification of a CTQ

My quote was two days late!

This policy is missing my endorsement!

This deal is three points below our pricing target!

This quote will not be bound!

We Feel CTQ Problems Every Day!!

Do You Understand Your Processes?

Are your processes mapped?Do your processes have performance metrics?Do you know your current performance levels?

If you don’t, how do you know what defects your Quality projects are eliminating?

What is a Defect?

It is NOT DONE.

It is DONE WRONG.

It is DONE LATE!

Recognizing a defect is the first step toward improvement

Questions for Leaders

Six Sigma is all about eliminating defects

Are my projects clustered around dramatically reducing my critical process defects?

Have I begun to focus my resources on these projects?

Will my customers really feel the improvements from my Quality efforts?

US CDT Loading

Reduce total elapsed time to process a CDT file to 24 hours

Scope is limited to the process loading, and repairing errors in cession data for mapped companies. The process starts with the file load process for CDT and ends when the transactions/cessions are available in the production database.

Baseline data indicates it takes a median of 96 elapsed hours to load a transaction file. At current staffing levels and process capacity, the backlog for the 66 CDT customers currently mapped would never be eliminated.

• Actuary: Accurate, complete data on key clients monthly

• Admin: CDT Data loaded within 24 hours of receipt of media

• Claims: Access to cession level information on claims & retro

• Pricing: Access to development & mortality data by company

• Actuary: Experience Analysis & Reserving

• Admin: Customer fulfillment and billing & collections

• Claims: Claim payment and retrocession collection

• Pricing: New business pricing and analysis

Productivity: CDT data has a potential fiscal benefit of $5MM annually, this benefit cannot be realized until the data supplied by clients can be loaded for analysis. Loading data enables all subsequent cession level analysis.
