Training Program

A reader asks what the expectations of the FDA are towards the “training program” and tips on changing the culture/attitude towards positive training behaviors.

I’ve answered the FDA part before in “Site Training Needs,” “Training Plan,” “CVs and JDs and Training Plans,” and “HR and Quality, joined at the hip” but I think it is a good idea to revisit the topic and look at some 483 observations.

Employees are not given training in the particular operations they perform as part of their function, current good manufacturing practices and written procedures required by current good manufacturing practice regulations.

Specifically, your firm does not have a written training program. There are no records to demonstrate (b)(6)(b. is qualified perform filling operations. I observed (b)(4)(b perform filling operation for Wart Control Extra Strength, 4 ml, lot USWCXx-4059 on 01/18/23. I observed (b (7)(C). perform reprocessing and packing operations. There are no records to demonstrate (b (7)C. is qualified perform these operations.

Employees are not given training in current good manufacturing practices and written procedures required by current good manufacturing practice regulations.

Specifically, your firm lacked training documentation for cGMP, SOPs, or specific job functions for all employees that perform analytical testing on finished OTC drug products. Additionally, your firm lacks a written procedure on employee training.

I could list a bunch more, but they all pretty much say the same.

  1. Have a documented training program.
  2. Conduct training on the operations an individual performs AND on general GxP principles appropriate to their job.

A documented training program should set out:

  1. Job Descriptions
  2. Organizational Charts
  3. Curriculum Vitae/Resume
  4. Identify Training
    • Individual Learning Plans (Training Assignments)
  5. Training Program Execution
    • Development and Management of Training Materials
    • Training execution
      • New Hire Orientation
      • On-the-Job Training (OJT)
      • Continuous Training
  6. Qualified Trainers
  7. Training Records of Personnel
  8. Periodic Review of Training System Performance

Conducting training starts with having a training plan to identify what appropriate training looks like.

The question is always what level of training is adequate. The honest answer is whatever works, and you aren’t training and educating your personnel enough. This is one of the things were the proof is in the pudding. Build the ways to measure effectiveness of training and you will be golden.

Maturity Models, Utilizing the Validation Program as an Example

Maturity models offer significant benefits to organizations by providing a structured framework for benchmarking and assessment. Organizations can clearly understand their strengths and weaknesses by evaluating their current performance and maturity level in specific areas or processes. This assessment helps identify areas for improvement and sets a baseline for measuring progress over time. Benchmarking against industry standards or best practices also allows organizations to see how they compare to their peers, fostering a competitive edge.

One of the primary advantages of maturity models is their role in fostering a culture of continuous improvement. They provide a roadmap for growth and development, encouraging organizations to strive for higher maturity levels. This continuous improvement mindset helps organizations stay agile and adaptable in a rapidly changing business environment. By setting clear goals and milestones, maturity models guide organizations in systematically addressing deficiencies and enhancing their capabilities.

Standardization and consistency are also key benefits of maturity models. They help establish standardized practices across teams and departments, ensuring that processes are executed with the same level of quality and precision. This standardization reduces variability and errors, leading to more reliable and predictable outcomes. Maturity models create a common language and framework for communication, fostering collaboration and alignment toward shared organizational goals.

The use of maturity models significantly enhances efficiency and effectiveness. Organizations can increase productivity and use their resources by identifying areas for streamlining operations and optimizing workflows. This leads to reduced errors, minimized rework, and improved process efficiency. The focus on continuous improvement also means that organizations are constantly seeking ways to refine and enhance their operations, leading to sustained gains in efficiency.

Maturity models play a crucial role in risk reduction and compliance. They assist organizations in identifying potential risks and implementing measures to mitigate them, ensuring compliance with relevant regulations and standards. This proactive approach to risk management helps organizations avoid costly penalties and reputational damage. Moreover, maturity models improve strategic planning and decision-making by providing a data-backed foundation for setting priorities and making informed choices.

Finally, maturity models improve communication and transparency within organizations. Providing a common communication framework increases transparency and builds trust among employees. This improved communication fosters a sense of shared purpose and collaboration, essential for achieving organizational goals. Overall, maturity models serve as valuable tools for driving continuous improvement, enhancing efficiency, and fostering a culture of excellence within organizations.

Business Process Maturity Model (BPMM)

A structured framework used to assess and improve the maturity of an organization’s business processes, it provides a systematic methodology to evaluate the effectiveness, efficiency, and adaptability of processes within an organization, guiding continuous improvement efforts.

Key Characteristics of BPMM

Assessment and Classification: BPMM helps organizations understand their current process maturity level and identify areas for improvement. It classifies processes into different maturity levels, each representing a progressive improvement in process management.

Guiding Principles: The model emphasizes a process-centric approach focusing on continuous improvement. Key principles include aligning improvements with business goals, standardization, measurement, stakeholder involvement, documentation, training, technology enablement, and governance.

Incremental Levels

    BPMM typically consists of five levels, each building on the previous one:

    1. Initial: Processes are ad hoc and chaotic, with little control or consistency.
    2. Managed: Basic processes are established and documented, but results may vary.
    3. Standardized: Processes are well-documented, standardized, and consistently executed across the organization.
    4. Predictable: Processes are quantitatively measured and controlled, with data-driven decision-making.
    5. Optimizing: Continuous process improvement is ingrained in the organization’s culture, focusing on innovation and optimization.

    Benefits of BPMM

    • Improved Process Efficiency: By standardizing and optimizing processes, organizations can achieve higher efficiency and consistency, leading to better resource utilization and reduced errors.
    • Enhanced Customer Satisfaction: Mature processes lead to higher product and service quality, which improves customer satisfaction.
    • Better Change Management: Higher process maturity increases an organization’s ability to navigate change and realize project benefits.
    • Readiness for Technology Deployment: BPMM helps ensure organizational readiness for new technology implementations, reducing the risk of failure.

    Usage and Implementation

    1. Assessment: Organizations can conduct BPMM assessments internally or with the help of external appraisers. These assessments involve reviewing process documentation, interviewing employees, and analyzing process outputs to determine maturity levels.
    2. Roadmap for Improvement: Organizations can develop a roadmap for progressing to higher maturity levels based on the assessment results. This roadmap includes specific actions to address identified deficiencies and improve process capabilities.
    3. Continuous monitoring and regular evaluations are crucial to ensure that processes remain effective and improvements are sustained over time.

    A BPMM Example: Validation Program based on ASTM E2500

    To apply the Business Process Maturity Model (BPMM) to a validation program aligned with ASTM E2500, we need to evaluate the program’s maturity across the five levels of BPMM while incorporating the key principles of ASTM E2500. Here’s how this application might look:

    Level 1: Initial

    At this level, the validation program is ad hoc and lacks standardization:

    • Validation activities are performed inconsistently across different projects or departments.
    • There’s limited understanding of ASTM E2500 principles.
    • Risk assessment and scientific rationale for validation activities are not systematically applied.
    • Documentation is inconsistent and often incomplete.

    Level 2: Managed

    The validation program shows some structure but lacks organization-wide consistency:

    • Basic validation processes are established but may not fully align with ASTM E2500 guidelines.
    • Some risk assessment tools are used, but not consistently across all projects.
    • Subject Matter Experts (SMEs) are involved, but their roles are unclear.
    • There’s increased awareness of the need for scientific justification in validation activities.

    Level 3: Standardized

    The validation program is well-defined and consistently implemented:

    • Validation processes are standardized across the organization and align with ASTM E2500 principles.
    • Risk-based approaches are consistently used to determine the scope and extent of validation activities.
    • SMEs are systematically involved in the design review and verification processes.
    • The concept of “verification” replaces traditional IQ/OQ/PQ, focusing on critical aspects that impact product quality and patient safety.
    • Quality risk management tools (e.g., impact assessments, risk management) are routinely used to identify critical quality attributes and process parameters.

    Level 4: Predictable

    The validation program is quantitatively managed and controlled:

    • Key Performance Indicators (KPIs) for validation activities are established and regularly monitored.
    • Data-driven decision-making is used to continually improve the efficiency and effectiveness of validation processes.
    • Advanced risk management techniques are employed to predict and mitigate potential issues before they occur.
    • There’s a strong focus on leveraging supplier documentation and expertise to streamline validation efforts.
    • Engineering procedures for quality activities (e.g., vendor technical assessments and installation verification) are formalized and consistently applied.

    Level 5: Optimizing

    The validation program is characterized by continuous improvement and innovation:

    • There’s a culture of continuous improvement in validation processes, aligned with the latest industry best practices and regulatory expectations.
    • Innovation in validation approaches is encouraged, always maintaining alignment with ASTM E2500 principles.
    • The organization actively contributes to developing industry standards and best practices in validation.
    • Validation activities are seamless integrated with other quality management systems, supporting a holistic approach to product quality and patient safety.
    • Advanced technologies (e.g., artificial intelligence, machine learning) may be leveraged to enhance risk assessment and validation strategies.

    Key Considerations for Implementation

    1. Risk-Based Approach: At higher maturity levels, the validation program should fully embrace the risk-based approach advocated by ASTM E2500, focusing efforts on aspects critical to product quality and patient safety.
    2. Scientific Rationale: As maturity increases, there should be a stronger emphasis on scientific understanding and justification for validation activities, moving away from a checklist-based approach.
    3. SME Involvement: Higher maturity levels should see increased and earlier involvement of SMEs in the validation process, from equipment selection to verification.
    4. Supplier Integration: More mature programs will leverage supplier expertise and documentation effectively, reducing redundant testing and improving efficiency.
    5. Continuous Improvement: At the highest maturity level, the validation program should have mechanisms in place for continuous evaluation and improvement of processes, always aligned with ASTM E2500 principles and the latest regulatory expectations.

    Process and Enterprise Maturity Model (PEMM),

    The Process and Enterprise Maturity Model (PEMM), developed by Dr. Michael Hammer, is a comprehensive framework designed to help organizations assess and improve their process maturity. It is a corporate roadmap and benchmarking tool for companies aiming to become process-centric enterprises.

    Key Components of PEMM

    PEMM is structured around two main dimensions: Process Enablers and Organizational Capabilities. Each dimension is evaluated on a scale to determine the maturity level.

    Process Enablers

    These elements directly impact the performance and effectiveness of individual processes. They include:

    • Design: The structure and documentation of the process.
    • Performers: The individuals or teams executing the process.
    • Owner: The person responsible for the process.
    • Infrastructure: The tools, systems, and resources supporting the process.
    • Metrics: The measurements used to evaluate process performance.

    Organizational Capabilities

    These capabilities create an environment that supports and sustains high-performance processes. They include:

    • Leadership: The commitment and support from top management.
    • Culture: The organizational values and behaviors that promote process excellence.
    • Expertise: The skills and knowledge required to manage and improve processes.
    • Governance: The mechanisms to oversee and guide process management activities.

    Maturity Levels

    Both Process Enablers and Organizational Capabilities are assessed on a scale from P0 to P4 (for processes) and E0 to E4 (for enterprise capabilities):

    • P0/E0: Non-existent or ad hoc processes and capabilities.
    • P1/E1: Basic, but inconsistent and poorly documented.
    • P2/E2: Defined and documented, but not fully integrated.
    • P3/E3: Managed and measured, with consistent performance.
    • P4/E4: Optimized and continuously improved.

    Benefits of PEMM

    • Self-Assessment: PEMM is designed to be simple enough for organizations to conduct their own assessments without needing external consultants.
    • Empirical Evidence: It encourages the collection of data to support process improvements rather than relying on intuition.
    • Engagement: Involves all levels of the organization in the process journey, turning employees into advocates for change.
    • Roadmap for Improvement: Provides a clear path for organizations to follow in their process improvement efforts.

    Application of PEMM

    PEMM can be applied to any type of process within an organization, whether customer-facing or internal, core or support, transactional or knowledge-intensive. It helps organizations:

    • Assess Current Maturity: Identify the current state of process and enterprise capabilities.
    • Benchmark: Compare against industry standards and best practices.
    • Identify Improvements: Pinpoint areas that need enhancement.
    • Track Progress: Monitor the implementation and effectiveness of process improvements.

    A PEMM Example: Validation Program based on ASTM E2500

    To apply the Process and Enterprise Maturity Model (PEMM) to an ASTM E2500 validation program, we can evaluate the program’s maturity across the five process enablers and four enterprise capabilities defined in PEMM. Here’s how this application might look:

                      Shipping Container Validation

                      Follow a systematic process to validate a shipping container by involving the traditional three main stages: Design Qualification (DQ), Operational Qualification (OQ), and Performance Qualification (PQ).

                      Design Qualification (DQ)

                      The DQ stage involves establishing that the shipping container design meets the user requirements and regulatory standards. Key steps include:

                      1. Define user requirement specifications (URS) for the container, including temperature range, duration of transport, and product-specific needs.
                      2. Review the container design specifications provided by the manufacturer.
                      3. Assess the container’s compatibility with the pharmaceutical product and its storage requirements.
                      4. Evaluate the container’s compliance with relevant regulatory guidelines and standards.

                      Operational Qualification (OQ)

                      OQ involves testing the container under controlled conditions to ensure it operates as intended. This stage includes:

                      1. Conducting empty container tests to verify basic functionality.
                      2. Testing temperature control systems and monitoring devices.
                      3. Evaluating the container’s ability to maintain required conditions under various environmental scenarios.
                      4. Assessing the ease of use and any potential operational issues.

                      Performance Qualification (PQ)

                      PQ is the most critical stage, involving real-world testing to ensure the container performs as required under actual shipping conditions. Steps include:

                      1. Develop a detailed PQ protocol that outlines test conditions, acceptance criteria, and data collection methods.
                      2. Conduct shipping trials using actual or simulated product loads.
                      3. Test the container under worst-case scenarios, including extreme temperature conditions and extended shipping durations.
                      4. Monitor and record temperature data throughout the shipping process.
                      5. Assess the impact of various handling conditions (e.g., vibration, shock) on container performance.
                      6. Evaluate the container’s performance across different shipping lanes and modes of transport.

                      Additional Considerations

                      • Associated Materials and Equipment: Ensure all associated materials (e.g., coolants, packaging materials) and monitoring equipment are also qualified.
                      • Re-qualification: For reusable containers, establish a process for periodic re-qualification to ensure ongoing performance.
                      • Documentation: Maintain comprehensive documentation of all qualification stages, including test results, data analysis, and conclusions.
                      • Risk Assessment: Conduct a risk assessment to identify potential failure modes and mitigation strategies.

                      Best Practices

                      1. Use a risk-based approach to determine the extent of testing required for each container type and shipping scenario.
                      2. Consider seasonal variations in ambient temperature profiles when designing qualification studies.
                      3. Utilize pre-qualified containers from reputable suppliers when possible to streamline the validation process.
                      4. Implement a robust change control process to manage any container or shipping process modifications post-validation.
                      5. Regularly review and update validation documentation to reflect any changes in regulatory requirements or shipping conditions.

                      Following this comprehensive approach, you can ensure that your shipping containers are properly validated for pharmaceutical transport, maintaining product quality and integrity throughout the supply chain. Validation is an ongoing process, and containers should be periodically reassessed to ensure continued compliance and performance.

                      Extractables and Leachables (E&L)

                      An effective program for managing extractables and leachables (E&L) in biotech involves a comprehensive approach that ensures product safety and compliance with regulatory standards. As single-use technologies have become more prevalent in biopharmaceutical manufacturing, leachables from bags, tubing, and other plastic components have become an area of concern. This has led to more rigorous supplier qualification and leachables risk assessment for single-use systems.

                      Extractables are chemical compounds that can be extracted from materials (like single-use systems, packaging, or manufacturing equipment) under exaggerated conditions such as elevated temperature, extended contact time, or use of strong solvents. They represent a “worst-case” scenario of chemicals potentially migrating into a drug product. Extractables are specific to the tested material and are independent of the drug product.

                      Leachables are chemical compounds that actually migrate from materials into the drug product under normal conditions of use or storage. They are specific to the combination of the material and the particular drug substance or product, representing the contaminants that may be present in the final drug formulation. Leachables are typically a subset of extractables that migrate under real-world conditions.

                      The accumulation of extractables and leachabes in a process fluid is governed by thermodynamics (the extent to which the materials would migrate) and kinetic (the rate at which would migrate) factors, as well as the amount of time during which such migration will occur. Higher temperatures increase the migration rate of leachables from the bulk of plastic to the surface in contact with the process stream or formulation.

                      Key points

                      • Extractables studies are performed on materials using exaggerated conditions.
                      • Leachables studies are performed on the actual drug product under normal conditions.
                      • Extractables represent potential contaminants, while leachables are actual contaminants.
                      • Both are critical for assessing product safety and quality in biotech manufacturing.

                      Proper evaluation of extractables and leachables is essential for regulatory compliance and ensuring patient safety in biopharmaceutical products.

                      Program Components

                      Design Space

                      The starting point should be a review of the supplier’s data. These studies should be performed on materials at the component level under standardized conditions of temperature time, surface, area, etc., so that the data is representative of intended use, including sterilization techniques. Using this data, the end-user can calculate the minimum amount of extractables based on surface area and other conditions. Consider the impact of dilution and clearance over the complete process through risk assessment and then complement with targeted studies.

                      These studies should be developed based on Quality-by-design principles described in ICH Q8 to gather all the attributes and parameters used to determine a design space. Scientific variables should be identified to set up the Design of Experiment (DoE) for the testing plan.

                      Risk Assessment

                      • Material Selection: Evaluate materials used for their potential to release harmful substances.
                      • Process Understanding: Understand the process conditions (e.g., temperature, pH, solvents) that might affect the leaching of chemicals.
                      • Risk Prioritization: Prioritize materials and processes based on their risk of contributing harmful leachables. Consider factors like stage of manufacturing, contact time, and proximity to final product.

                      The risk assessment needs to be within the overall context of process performance and product safety and efficacy. It should not be a separate risk assessment. You will dive deeper with more specific risk questions, but the hazard identification starts at the process level. In evaluating risks the following factors should be considered:

                      • Proximity of the process steps undergoing a change to the final product. Polymeric components in process steps closer to DS or DP will carry a higher risk rating than those in upstream process steps. For example, a bag or filter used for the final filtration of bulk drug substance (BDS) will have a much higher risk rating than components used in upstream process steps since there are no purification steps post-UF/DF.
                      • Storage and processing conditions (e.g., duration of exposure, temperature, pressure, pH extremes, buffer extraction propensity)
                      • The type of process fluid (e.g., purification buffer versus formulated drug substance, presence of solubilizing agents)
                      • Construction materials
                      • Potential adverse events, including synergistic and additive affects
                      • Drug dose, mode, and frequency of administration
                      • Therapeutic necessity

                      Your risk assessment will drive study design and should consider:

                      Analytical challenges

                      • Detecting and quantifying trace levels of leachables, which are often present at extremely low concentrations
