Cultural Scores & Site Performance Key Quality Metrics

Pharmaceutical OnlineKen Congdon, 26 May 2015

Stronger culture is correlated with fewer action limit excursions in steriles

1/4 ISPE



Stronger culture scores are associated with higher lot acceptance

2/4 ISPE



Sites with higher quality culture scores have lower deviations recurrence

3/4 ISPE



Sites with higher quality culture scores have higher CAPA effectiveness

4/4 ISPE

Identified Essential Attributes for Culture of Quality

Harvard Business ReviewSurvey April 2014

Leadership Emphasis

Message Credibility

Peer Involvement

Employee Ownership



Maintaining a leadership emphasis on quality

What they say & What they do

1/4

Even when executives have the best intentions, there are often gaps b/w

What they say & What they doAs a result, employees get mixed messages about

whether quality is truly important. Company leaders must first buy into quality improvement initiatives and clearly demonstrate their own personal commitment to this effort

to employees



Ensuring Message Credibility

One Message

2/4

Quality messaging should be tailored in such a way that it resonates with every employee.

Different messages may need to be developed to resonate appropriately with employees at

different sites.

The key is to regularly test these messages with employees, solicit their feedback, and refresh

these messages over time if necessary



Encouraging Peer Involvement

Participation

3/4

A variety of different tactics can be used to create positive social pressure that encourages employees to participate in (& even generate) quality initiatives. These can include friendly

“quality competitions”.The key is to test these tactics and solicit

feedback to see which are most effective with employees.



Increasing Ownership & Empowerment

Engage in Decisions

4/4

Employees should be free to apply their own judgment to situations that fall outside the

common directive. Providing the right level of guidance is crucial to this effort

but they must know how to act when they encounter specific quality issues.

Visible Signals of Quality Culture

Right tone at the top

Focus on the right value

Constant display of putting patient

above everything

Constant display of concern for quality

Consistently walks the talk

With great people skill

& strong value

More than financial rewards

Roots of Strong Quality Culture

Introduction of Improvement & Innovation for quality driven productivity

Adaptation & Investment in Technology to ensure state of control over system

Promotion of change & continuous improvement in Quality System

Roots of Strong Quality Culture

Prompt adaptation of best practice, low staff rotation

Proactive & transparent behavior

Strong relationship based on dialogue, science & mutual respect

Principle of Quality Culture

Product & Process Understanding Sensible Business Management

Sufficient depth of science to explain why deviations have not impacted on quality of

product

Too fast growth & operating at limit of capacity triggers often

issues & non-compliance

How mature is your quality system

1 2 3 4

Level

Richard L. Friedman, FDLI Workshop Washington DC, July 2014US-FDA

Small problems ultimately snowball into larger ones, and management becomes aware only when there is a crisis


1 2 3 4

Level


Nearly always reactive, but there is willingness to change. Patchwork corrections are the norm


1 2 3 4

Level


More proactive. Increasingly detects emerging adverse trends, surfaces major issues, and makes lasting manufacturing and

system improvements


1 2 3 4Level


Routinely acts preventively as described in level 3. Fully institutionalizes and reinforces (rewards) a vigilant culture that makes meaningful manufacturing and systemic improvements

Systems Thinking

System is the product of interacting parts

Improving the parts taken separately will not improve the system

Quality is everyone’s responsibility

Selected Quotes, W. Edwards Deming

Lack of knowledge …

that is the problem

If you do not know how to ask

the right question, you

discover nothing

If you can’t describe what you are doing as a process, you don’t know what you are

doing

Rational behavior requires theory.

Reactive behavior requires only reflex

action

Whenever there is fear, you will

get wrong figures

Learning is not compulsory … neither is survival

Strong Quality Culture Efficient Quality System Consistent manufacturing

It’s the culture that decides the path

Poor Quality Culture Unreliable Quality System Defects and Recall

cross-contamination … employees move

Attix stance: We have carefully cleaned

everything before use

Regulatory Stance: Cleaning is not a

substitute for segregating products

Cross-contamination with sensitizing agents

can initiate life-threatening allergic

reactions

No safe level of penicillin

a tolerable risk

Do you calculate a cost of poor quality

at your site?

ISPE/PDA Survey Sep 2011

Have you evaluated the cost of improving quality

vs. the cost of failure (recalls, rejections, low yield, downtime etc)?

ISPE/PDA Survey Sep 2011

Lets make it simple, clear & loud

Me, my kids & parents use same

drug which I manufacture

No batch has ever failed

Drug manufactured in non-cGMPenvironment

It does not mean that there is necessarily something wrong with the drug

But “intention in question”

Please remember

Lack of adverse event reports, or “something is wrong” is NOT the same

as evidence of no harm….

Closing words

Innocence

• Quality mainly outsourced to regulators

Awareness

• Quality unit will identify the issue

Understanding

• Quality system & Metrics reveals reality & drives action

Competence

• Quality mind set in all functions. Design quality in & anticipate issues

Excellence

• Competitive advantage through prevention of quality issues

Journey of uncertainty to certainty matters

The question is how useful can we make standards
