Questions and Answers(R4) 

 
 
This guidance represents the Food and Drug Administrations (FDAs) current thinking on this topic.  It 
does not create or confer any rights for or on any  person and does not operate to bind FDA or the public.  
You can use an alternative approach if the approach satisfies the requirements of the applicable statutes 
and regulations. If you want to discuss an alternative approach, contact the FDA staff responsible for 
implementing this guidance.  If you cannot identify the appropriate FDA staff, call the appropriate 
number listed on the title page of this guidance.  
 
I.  INTRODUCTION (1)2  
 
Since the Q8, Q9, and Q10 guidances were made final, experiences implementing the guidances 
in the ICH regions have given rise to requests for clarification.  This question and answer (Q&A) 
document is intended to clarify key issues.  The guidance reflects the current working procedure 
of the ICH Quality Implementation Working Group (Q-IWG) for implementing the Q8, Q9, and 
Q10 guidances. 
 
This guidance is a revision of the ICH guidance titled Q8, Q9, and Q10 Questions and Answers  
(May 2010). In November 2010, the May 2010 guidance was revised to add Q&A9 to section 
II.B.1 Design Space (2.1). 
 
The benefits of harmonizing technical requirements across the ICH regions can be realized only 
if the various quality ICH guidances are implemented and interpreted in a consistent way across 
the three regions. The Q-IWG is tasked to develop Q&As to facilitate implementation of existing 
quality guidance. 
 
The Q&As reference the following ICH guidances available on the Internet at 
http://www.fda.gov/Drugs/GuidanceComplianceRegulatoryInformation/Guidances/default.htm  
under International Conference on Harmonisation  Quality: 
                                                 
1  This guidance was developed within  the Quality Implementation Working Group of the International Conference 
on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH) and has  
been subject to consultation  by the regulatory parties, in  accordance with the ICH process.  The Q&As in this 
document have been endorsed by the ICH Steering Committee at  Step 4  of the ICH process, April 2009, June 2009, 
October 2009, and November 2010.  At  Step 4  of the process, the final draft is recommended for adoption to the 
regulatory bodies of the European  Union, Japan, and the United States.

II. 	 QUESTIONS AND ANSWERS 
 
A. 	 For General Clarification (1.1) 
Q1: 	 Is the minimal approach accepted by regulators?  
A1: 	 Yes. The minimal approach as defined in Q8(R2) (sometime also called baseline 
or traditional approach) is the expectation that is to be achieved for a fully 
acceptable submission.  However, the enhanced approach as described in ICH 
Q8(R2) is encouraged (Ref. Q8(R2) Annex, appendix 1).  (Approved June 2009) 
 
Q2: 	 What is an appropriate approach for process validation using ICH Q8, Q9, and 
Q10? 
A2: 	 The objectives of process validation are unchanged when using ICH Q8, Q9, and 
Q10. The main objective of process validation remains that a process design yields 
a product meeting its predefined quality criteria. ICH Q8, Q9, and Q10 provide a 
structured way to define product critical quality attributes, design space, the 
manufacturing process, and the control strategy. This information can be used to 
identify the type and focus of studies to be performed prior to and on initial 
commercial production batches. As an alternative to the traditional process 
validation, continuous process verification (see definition in ICH Q8(R2) 
glossary) can be utilized in process validation protocols for the initial commercial 
production and for manufacturing process changes for the continual improvement 
throughout the remainder of the product lifecycle. (Approved October 2009)  
 
Q3: 	 How can information from risk management and continuous process 
verification provide for a robust continual improvement approach under ICH 
Q8, Q9 and Q10? 
  2
  Contains Nonbinding Recommendations  
A3: 	 Like the product itself, process validation also has a lifecycle (process design, 
process qualification and ongoing process verification). A risk assessment 
conducted prior to initial commercial validation batches can highlight the areas 
where particular focus and data collection could demonstrate the desired high 
level of assurance of commercial process robustness. Continual monitoring (e.g., 
via continuous process verification) can further demonstrate the actual level of 
assurance of process consistency and provide the basis for continual improvement 
of the product. Quality Risk Management methodologies of ICH Q9 can be 
applied throughout the product lifecycle to maintain a state of process control.  
(Approved October 2009) 
 
B.  Quality by Design (QbD) Topics (2) 
 
Q1: 	 Is it always necessary to have a design space (DS) or real-time release (RTR) 
testing to implement QbD?   
  
A1: 	 Under Quality by Design, establishing a design space or using real-time release 
testing is not necessarily expected (ICH Q8(R2)).  (Approved April 2009) 
 
1. 	 Design Space (2.1)  
 
Q1: 	 Is it necessary to study multivariate interactions of all parameters to develop a 
design space? 
 
A1: 	 No, the applicant should justify the choice of material attributes and parameters 
for multivariate experimentation based on risk assessment and desired operational 
flexibility. (Approved April 2009) 
 
 
Q2: 	 Can a design space be applicable to scale-up? 
 
A2: 	 Yes, when appropriately justified (for additional details, see Q8(R2) Annex 
section II.D.4 (2.4.4)). An example of a scale-independent design space is 
provided in the European Federation of Pharmaceutical Industries and 
Associations (EFPIA) Mock P2 document (EFPIA Mock P2 submission on 
Examplain: Chris Potter, Rafael Beerbohm, Alastair Coupe, Fritz Erni, Gerd 
Fischer, Staffan Folestad, Gordon Muirhead, Stephan Roenninger, Alistair 
Swanson, A guide to EFPIAs Mock P.2 Document, Pharm. Tech. (Europe), 18, 
December 2006, 39-44).  
 
 This example may not reflect the full regulatory requirements for a scale-up. 
(Approved April 2009) 
 
 
Q3: 	  Can a design space be applicable to a site change? 
 
  3
  Contains Nonbinding Recommendations  
A3: 	 Yes, it is possible to justify a site change using a site independent design space 
based on a demonstrated understanding of the robustness of the process and an in 
depth consideration of site specific factors (e.g., equipment, personnel, utilities, 
manufacturing environment, and equipment).  There are region specific regulatory 
requirements associated with site changes that need to be followed. (Approved 
April 2009) 
 
Q4: 	  Can a design space be developed for  single and/or multiple unit operations? 
 
A4: 	 Yes, it is possible to develop a design space for single unit operations or across a 
series of unit operations (see Q8(R2) Annex, section II.D.3 (2.4.3)). (Approved 
April 2009) 
 
 
Q5 	 Is it possible to develop a design space for existing products? 
 
A5: 	 Yes, it is possible. Manufacturing data and process knowledge can be used to 
support a design space for existing products. Relevant information should be 
utilized from e.g., commercial scale manufacturing, process improvement, 
corrective and preventive action (CAPA), and development data. 
For manufacturing operations run under narrow operational ranges in fixed 
equipment, an expanded region of operation and an understanding of multi-
parameter interactions may not be achievable from existing manufacturing data 
alone and additional studies may provide the information to develop a design 
space. Sufficient knowledge should be demonstrated, and the design space should 
be supported experimentally to investigate interactions and establish 
parameter/attribute ranges. (Approved April 2009) 
 
 
Q6: 	 Is there a regulatory expectation to develop a design space for an existing 
product? 
 
A6: 	 No, development of design space for existing products is not necessary unless the 
applicant has a specific need and desires to use a design space as a means to 
achieve a higher degree of product and process understanding. This may increase 
manufacturing flexibility and/or robustness. (Approved April 2009) 
 
Q7: 	 Can a design space be applicable to formulation?  
A7: 	 Yes, it may be possible to develop formulation (not component but rather 
composition) design space consisting of the ranges of excipient amount and its 
physicochemical properties (e.g., particle size distribution, substitution degree of 
polymer) based on an enhanced knowledge over a wider range of material 
attributes. The applicant should justify the rationale for establishing the design 
space with respect to quality attributes such as bioequivalence, stability, 
manufacturing robustness etc. Formulation adjustment within the design space 
  4
  Contains Nonbinding Recommendations  
depending on material attributes does not need a submission in a regulatory 
postapproval change. (Approved June 2009) 
Q8: 	 Does a set of proven acceptable ranges alone constitute a design space?  
A8: 	 No, a combination of proven acceptable ranges (PARs) developed from univariate 
experimentation does not constitute a design space (see Q8(R2) Annex, section 
II.D.5 (2.4.5)). Proven acceptable ranges from only univariate experimentation 
may lack an understanding of interactions between the process parameters and/or 
material attributes. However proven acceptable ranges continue to be acceptable 
from the regulatory perspective but are not considered a design space (see ICH 
Q8(R2) Annex, section II.D.5 (2.4.5)). 
   
  The applicant may elect to use proven acceptable ranges or design space for 
different aspects of the manufacturing process. (Approved June 2009) 
 
Q9: 	 Should the outer limits of the design space be evaluated during process 
validation studies at the commercial scale? 
A9: 	 No. There is no need to run the qualification batches at the outer limits of the 
design space during process validation studies at commercial scale. The design 
space should be sufficiently explored earlier during development studies (for 
scale-up, see also section II.B.1 Design Space (2.1), Q2; for lifecycle approach, 
see section II.A For General Clarification (1.1), Q3).  (Approved November 2010) 
 
 
2. 	 Real-Time Release Testing (2.2)  
 
Q1: 	  How is batch release affected by employing real-time release testing?  
A1: 	 Batch release is the final decision to release the product to the market regardless 
of whether RTR testing or end-product testing is employed. End-product testing 
involves performance of specific analytical procedures on a defined sample size 
of the final product after completion of all processing for a given batch of that 
product. Results of real-time release testing are handled in the same  manner as 
end-product testing results in the batch release decision. Batch release involves an 
independent review of batch conformance to predefined criteria through review of 
testing results and manufacturing records together with appropriate good 
manufacturing practice (GMP) compliance and quality system, regardless of 
which approach is used. (Approved April 2009) 
 
Q2: 	 Does real-time release testing mean elimination of end-product testing?  
A2: 	 Real-time release testing does not necessarily eliminate all end-product testing.  
For example, an applicant can propose RTR testing for some attributes only or not 
all. If all critical quality attributes (CQAs) (relevant for real-time release testing)  
  5
  Contains Nonbinding Recommendations  
are assured by in-process monitoring of parameters and/or testing of materials, 
then end-product testing might not be needed for batch release. Some product 
testing will be expected for certain regulatory processes such as stability studies 
or regional requirements. (Approved April 2009) 
 
Q3: 	 Is a product specification still necessary in the case of RTR testing? 
A3: 	 Yes, product specifications (see ICH Q6A and Q6B) still need to be established 
and met, when tested.3  (Approved April 2009) 
 
Q4: 	 When using RTR testing, is there a need for stability test methods? 
A4: 	 Even where RTR testing is applied, a stability monitoring protocol that uses  
stability indicating methods is required4 for all products regardless of the means 
of release testing (see ICH Q1A and ICH Q5C).  (Approved April 2009) 
 
Q5: 	 What is the relationship between control strategy and RTR testing? 
A5: 	 RTR testing, if utilized, is an element of the control strategy in which tests and/or 
monitoring can be performed as in-process testing (in-line, on-line, at-line) rather 
than tested on the end product. (Approved April 2009) 
 
Q6: 	 Do traditional sampling approaches apply to RTR testing? 
A6: 	 No, traditional sampling plans for in-process and end-product testing involve a 
discrete sample size that represents the minimal sampling expectations. Generally, 
the use of RTR testing will include more extensive on-line/in-line measurement. 
A scientifically sound sampling approach should be developed, justified, and 
implemented. (Approved April 2009) 
 
Q7: 	 If RTR testing results fail or trending  toward failure, can end-product testing be 
used to release the batch? 
A7: 	 No, in principle the RTR testing results should be routinely used for the batch 
release decisions and not be substituted by end-product testing. Any failure should 
be investigated and trending should be followed up appropriately. However, batch 
release decisions should be made based on the results of the investigations. In the 
case of failure of the testing equipment, please refer to the previous question. The 
batch release decision should comply  with the content of the marketing 
authorization and GMP compliance.  (Approved April 2009)

  Contains Nonbinding Recommendations  
Q8: 	 What is the relationship between in-process testing and RTR testing? 
 
A8: 	 In-process testing includes any testing that occurs during the manufacturing 
process of drug substance and/or finished product. Real-time release testing 
includes those in-process tests that have a direct impact on the decision for batch 
release through evaluation of critical quality attributes.  (Approved June 2009) 
 
Q9: 	 What is the difference between real time release and real-time release 
testing? 
A9: 	 The definition of real-time release testing in Q8(R2) is the ability to evaluate 
and ensure the acceptable quality of in-process and/or final product based on 
process data, which typically includes a valid combination of measured material 
attributes and process controls. 
  The term  real time release in the Q8(R2), step 2 document was revised to real-
time release testing in the final Q8(R2) Annex to fit the definition more 
accurately and thus avoid confusion with batch release.  (Approved June 2009) 
Q10: 	 Can surrogate measurement be used for RTR testing? 
A10: 	 Yes, RTR testing can be based on measurement of a surrogate (e.g., process 
parameter, material attribute) that has been demonstrated to correlate with an in-
process or end-product specification (see ICH Q8(R2); Annex, section II.E (2.5)).  
(Approved June 2009) 
 
Q11: 	 What is the relationship between RTR testing and parametric release?  
A11: 	 Parametric release is one type of RTR testing. Parametric release is based on 
process data (e.g., temperature, pressure, time for terminal sterilization, 
physicochemical indicator) rather than the testing of material and/or a sample for 
a specific attribute. (Approved October 2009) 
 
3. 	 Control Strategy (2.3)  
 
Refer to the definition of  control strategy provided in the ICH Q10 glossary: 
  
A planned set of controls, derived from current product and process 
understanding that assures process performance and product quality. The controls 
can include parameters and attributes related to drug substance and drug product 
materials and components, facility and equipment operating conditions, in-
process controls, finished product specifications, and the associated methods and 
frequency of monitoring and control. 
 
Q1:   What is the difference in a control strategy for products developed using the 
minimal approach vs. quality-by-design approach? 
  7
  Contains Nonbinding Recommendations  
 
A1: 	 Control strategies are expected irrespective of the development approach. Control 
strategy includes different types of control proposed by the applicant to assure 
product quality (ICH Q10, section IV.B.1 (3.2.1)), such as in-process testing and 
end-product testing. For products developed following the minimal approach, the 
control strategy is usually derived empirically and typically relies more on 
discrete sampling and end-product testing. Under QbD, the control strategy is 
derived using a systematic science and risk-based approach. Testing, monitoring, 
or controlling is often shifted earlier into the process and conducted in-line, on-
line, or at-line testing. (Approved April 2009) 
 
Q2: 	 Are GMP requirements different for batch release under QbD? 
 
A2: 	 No, the same GMP requirements apply for batch release under minimal and QbD 
approaches. (Approved April 2009) 
 
Q3: 	 What is the relationship between a design space and a control strategy? 
 
A3: 	 A control strategy is required for all products.5 If a design space is developed and 
approved, the control strategy (see ICH Q8(R2), Annex, section IV (4)) provides 
the mechanism to ensure that the manufacturing process is maintained within the 
boundaries described by the design space. (Approved April 2009) 
 
Q4: 	 What approaches can be taken in the event of on-line/in-line/at-line testing or 
monitoring equipment breakdown? 
A4: 	 The control strategy provided in the application should include a proposal for use 
of alternative testing or monitoring approaches in cases of equipment failure. The 
alternative approach could involve use of end-product testing or other options, 
while maintaining an acceptable level of quality. Testing or monitoring equipment 
breakdown should be managed in the context of a deviation under the quality 
system and can be covered by GMP inspection.  (Approved June 2009) 
 
Q5: 	 Are product specifications different for minimal versus QbD approaches?  
A5: 	 In principle no, product specifications are the same for minimal and QbD 
approaches. For a QbD approach, the control strategy can facilitate achieving the 
end product specifications via real time release testing approaches (see ICH 
Q8(R2) Annex, appendix 1). Product must meet specification, when tested.6  
(Approved October 2009)

C.  Pharmaceutical Quality System (3) 
 
Q1:   What are the benefits of implementing a pharmaceutical quality system (PQS) 
(in accordance with ICH Q10)? 
 
A1: 	 The benefits are: 
 	  Facilitated robustness of the manufacturing process, through facilitation of 
continual improvement through science and risk-based postapproval change 
processes 
 	  Consistency in the global pharmaceutical environment across regions 
 	  Enable transparency of systems, processes, and organizational and 
management responsibility 
 	  Clearer understanding of the application of a quality system throughout 
product lifecycle 
 	  Further reducing risk of product failure and incidence of complaints and 
recalls, thereby providing greater assurance of pharmaceutical product 
consistency and availability (supply) to the patient 
 	  Better process performance 
 	  Opportunity to increase understanding between industry and regulators and 
more optimal use of industry and regulatory resources; enhance 
manufacturers and regulators confidence in product quality 
 	  Increased compliance with GMPs, which builds confidence in the regulators 
and may result in shorter inspections 

(Approved April 2009) 

 
Q2:  How does a company demonstrate implementation of PQS in accordance with 
ICH Q10? 
 
A2: 	 When implemented, a company will demonstrate the use of an effective PQS 
through its documentation (e.g., policies, standards), its processes, its 
training/qualification, its management, its continual improvement efforts, and its 
performance against pre-defined key performance indicators (see ICH Q10 
glossary on performance indicator). 
 
A mechanism should be established to demonstrate at a site how the PQS operates 
across the product lifecycle, in an easily understandable way for management, 
staff, and regulatory inspectors, e.g., a quality manual, documentation, flowcharts, 
procedures. Companies can implement a program in which the PQS is routinely 
audited in-house (i.e., internal audit program) to ensure that the system is 
functioning at a high level. (Approved April 2009) 
 
Q3: 	  Is it necessary to describe the PQS in a regulatory submission? 
 
A3: 	 No, however relevant elements of the PQS (such as quality monitoring system, 
change control, and deviation management) can be referenced as part of the 
control strategy as supporting information. (Approved April 2009) 
  9
  Contains Nonbinding Recommendations  
 
Q4: 	 Will there be certification that the PQS is in accordance with ICH Q10? 
 
A4: 	 No. There will not be a specific ICH Q10 certification program. (Approved April 
2009) 
 
Q5: 	 How should the implementation of the design space be evaluated during 
inspection of the manufacturing site? 
 
A5: 	 Inspection should verify/assess that manufacturing operations are appropriately 
carried out within the design space. The inspector in collaboration with the 
assessor, where appropriate, should also verify successful manufacturing 
operations under the design space and that movement within the design space is 
managed within the companys change management system (see ICH Q10, 
section IV. B.3 (3.2), Table III). (Approved April 2009) 
 
Q6: 	 What should be done if manufacturing operations run inadvertently outside of  
the design space? 
 
A6: 	 This should be handled as a deviation under GMP. For example, unplanned one-
off excursions occurring as a result of unexpected events, such as operator error 
or equipment failure, would be investigated, documented, and dealt with as a 
deviation in the usual way. The results of the investigation could contribute to the 
process knowledge, preventive actions, and continual improvement of the 
product. (Approved April 2009) 
Q7: 	 What information and documentation of the development studies should be 
available at a manufacturing site? 
A7: 	 Pharmaceutical development information (e.g., supporting information on design 
space, chemometric model, risk management) is available at the development site. 
Pharmaceutical development information that is useful to ensure the 
understanding of the basis for the manufacturing process and control strategy, 
including the rationale for selection of critical process parameters and critical  
quality attributes, should be available at the manufacturing site.  
Scientific collaboration and knowledge sharing between pharmaceutical 
development and manufacturing is essential to ensure the successful transfer to 
production. (Approved June 2009) 
Q8: 	 Can process parameters be adjusted throughout the product lifecycle? 
A8: 	 Process parameters are studied and selected during pharmaceutical development 
and monitored during commercial manufacturing. Knowledge gained could be 
utilized for adjustment of the parameters as part of continual improvement of the 
process throughout the lifecycle of the drug product (see ICH Q10, section IV 
(3)). (Approved June 2009)

  Contains Nonbinding Recommendations  
 
D.  Impact of New ICH Quality Guidance on GMP Inspection Practices (4) 
 
Q1:  	How will product-related inspections differ in an ICH Q8, Q9 and Q10 
environment? 
 
A1: 	 In the case of product-related inspection (in particular, preauthorization) 
depending on the complexity of the product and/or process, greater collaboration 
between inspectors and assessors could be helpful (for example, for the 
assessment of development data). The inspection would normally occur at the 
proposed commercial manufacturing site, and there is likely to be greater focus on 
enhanced process understanding and understanding relationships, e.g., critical 
quality attributes (CQAs), critical process parameters (CPPs).  The inspection 
might also focus on the application and implementation of quality risk 
management principles, as supported by the pharmaceutical quality system (PQS). 
(Approved April 2009) 
 
Q2:  	How will system-related inspections differ in an ICH Q8, Q9, and Q10 
environment? 
 
A2: 	 The inspection process will remain similar. However, upon the implementation of 
ICH Q8, Q9, and Q10, inspections will have greater focus on (but not only focus 
on) how the PQS facilitates the use of  e.g., quality risk management methods, 
implementation of design space, and change management (see ICH Q10). 
(Approved April 2009) 
 
Q3: 	 How is control strategy approved in the application and evaluated during  
inspection?  
 
A3: 	 Elements of control strategy submitted in the application will be reviewed and 
approved by the regulatory agency. However, additional elements are subject to 
inspection (as described in Q10).  (Approved October 2009) 
 
E.  	Knowledge Management (5) 
 
Q1: 	 How has the implementation of ICH Q8, Q9, and Q10 changed the significance 
and use of knowledge management? 
 
A1:  	Q10 defines knowledge management as: Systematic approach to acquiring, 
analyzing, storing, and disseminating information related to products, 
manufacturing processes and components. 
 
Knowledge management is not a system; it enables the implementation of the 
concepts described in ICH Q8, Q9 and Q10.

Knowledge management is not a new concept. It is always important regardless of 
the development approach. Q10 highlights knowledge management because it is 
expected that more complex information generated by appropriate approaches 
(e.g., QbD, process analytical technology (PAT), real-time data generation, and 
control monitoring systems) should be better captured, managed, and shared 
during product life-cycle. 
 
In conjunction with quality risk management, knowledge management can 
facilitate the use of concepts such as prior knowledge (including from other 
similar products), development of design space, control strategy, technology 
transfer, and continual improvement across the product life cycle. (Approved 
April 2009) 
 
Q2: 	 Does Q10 suggest an ideal way to manage knowledge? 
 
A2: 	 No. Q10 provides a framework and does not prescribe how to implement 
knowledge management. Each company decides how to manage knowledge, 
including the depth and extent of information assessment based on its specific 
needs. (Approved April 2009) 
 
Q3: 	 What are potential sources of information for knowledge management? 
 
A3: 	 Some examples of knowledge sources are: 
 	  Prior knowledge based on experience obtained from similar processes 
(internal knowledge, industry scientific and technical publications) and 
published information (external knowledge: literature and peer-reviewed 
publications) 
 	  Pharmaceutical development studies  
 	  Mechanism of action 
 	  Structure/function relationships 
 	  Technology transfer activities 
 	  Process validation studies 
 	  Manufacturing experience, e.g., 
 	 Internal and vendor audits 
 	 Raw material testing data  
 	  Innovation 
 	  Continual improvement  
 	  Change management activities 
 	  Stability reports 
 	  Product quality reviews/annual product reviews 
 	  Complaint reports 
 	  Adverse event reports (patient safety) 
 	  Deviation reports, recall Information 
 	  Technical investigations and/or CAPA reports 
 	  Suppliers and contractors

   Product history and /or manufacturing history 
   Ongoing manufacturing processes information (e.g., trends) 
 
Information from the above can be sourced and shared across a site or company, 
between companies and suppliers/contractors, products, and across different 
disciplines (e.g., development, manufacturing, engineering, quality units). 
(Approved April 2009) 
 
Q4: 	 Is a specific dedicated, computerized information management system required 
for the implementation of knowledge management with respect to ICH Q8, Q9, 
and Q10? 
 
A4: 	 No, but such computerized information management systems can be invaluable in 
capturing, managing, assessing, and sharing complex data and information. 
(Approved April 2009) 
 
Q5: 	 Will regulatory agencies expect to see a formal knowledge management  
approach during inspections? 
A5: 	 No. There is no added regulatory requirement for a formal knowledge 
management system. However, it is expected that knowledge from different 
processes and systems will be appropriately utilized. 
Note: formal means: it is a structured approach using a recognized methodology 
or information technology (IT) tool, executing and documenting something in a 
transparent and detailed manner. (Approved June 2009)

Q1: 	 With the rapid growth of the new science and risk-based quality paradigm 
coupled with the IWG efforts to facilitate globally consistent implementation of 
Q8, Q9, and Q10, a number of commercial vendors are now offering products 
that are being marketed as ICH compliant solutions or ICH Q8, 9, and 10 
Implementation software, etc. Is it necessary for a pharmaceutical firm to 
purchase these products to achieve a successful implementation of these ICH 
guidances within their companies? 
 
A1: 	 No. The ICH Implementation Working Group has not endorsed any commercial 
products and does not intend to do so. ICH is not a regulatory agency with 
reviewing authority and thus does not have a role in determining or defining ICH 
compliance for any commercial products.  While there will likely be a 
continuous proliferation of new products targeting the implementation of these 
ICH guidances, firms should carry out their own evaluation of these products 
relative to their business needs. (Approved April 2009)
