Introduction
This document belongs to the documents supporting EN 9200 relating to the programme
management specification.
This document is written in accordance with the documentary system linked to EN 9200 and takes
account of the current and almost systematic interconnection between the manufacturing and
inspection activities of the product, in keeping with quality management practices.
The manufacturing and inspection file (MIF), and the associated justifications (MIJF), form part of the
output data of the industrialization process. They are intended mainly for actors of the production
process and provide the justifications required by the design and development processes, and by the
acquiring customer. They are elaborated by the actors of industrialization, in partnership with the
actors of development and production.
1 Scope
The aim of a MIF and the associated justifications is to ensure that manufacturing and/or inspection
operations are realized in a compliant and reproducible manner.
The purpose of this document is to provide a guide to the elaboration of the MIF and the associated
justifications by:
— positioning them within the framework:
o of a programme and its objectives, on the one hand;
o of the realization of a product, on the other;
— describing, until production of the product ceases:
o the principles and conditions applying to the elaboration and then the validation of the MIF
within the framework of the industrialization process;
o the principles and conditions applying to the elaboration and then the validation of the MIJF
associated with the MIF, within the framework of the industrialization process;
o the principles and change and control conditions applying to the MIF and the MIJF.
This document can be used for all processes or sets of processes implemented on a tangible product,
which may incorporate software associated with the product. It does not apply to purely software
product, commercial-off-the-shelf product (catalogue part) or service (intangible product).
This document applies more particularly to serial production. Nevertheless, the principles and
conditions set forth in this document may be applied, making any necessary adaptations, to unit
production or to the realization of products to meet development needs (prototypes,
demonstrators, etc.).
This document covers the MIF and the MIJF of a product, including the activities related to procurement
and the associated industrial means in particular.

5 Concepts
5.1 Scope and interactions
The industrialization process is closely linked to the design and production processes in order to be
able to identify and take account of, at the earliest possible stage of the product definition, the
requirements (contractual, regulatory authorities, etc.), the internal industrial strategies (production
capacity, make or buy, etc.) and the technological constraints (performance of the means of production,
compatibility of the processes, etc.).
The industrialization process begins right at the start of product design and continues as the definition
data file (DDF) progresses, as part of a concurrent engineering approach.
As a general rule, the industrialization of a product is prepared and realized in parallel and consistently
with the detailed design process.
For products with long procurement/manufacturing/factory assembly lead times, or for complex
products, and depending on their readiness level, it may be necessary to anticipate the industrialization
activities in order to meet the cost, deadline, capability, safety, performance and quality targets.
The risks incurred by this anticipation need to be analysed and managed as part of the programme.
The execution logic described below (see Figure 1) shows how the industrialization and production
system qualification processes interact with the development (expression of need, design, etc.) and
production processes.

Figure 1 — Processes interfaced with the industrialization process
NOTE A “finalized” file (DDF, MIF, etc.) is a file with a status that meets the internal requirements of the
organization and is submitted to the customer and/or the acceptance authority.
The industrialization process covers several aspects: the industrialization of the product itself, the
elaboration of the manufacturing and inspection file (MIF), the elaboration of the associated
justifications and the qualification of the production system.
The industrialization process of a product needs coordination with the product design process in terms
of methods, synchronization, participants, etc. It obeys the programme management rules and takes
account of the constraints and relations between the various industrialization programmes.
The MIF and the associated justifications [manufacturing and inspection justification plan (MIJP) and
manufacturing and inspection justification file (MIJF)] are elaborated by the manufacturer responsible
for supplying the product on the basis of the DDF (see RG.Aero 000 14).
The elements of the justifications may be analysed and validated, in part or in full, by a third party or by
the manufacturer itself, depending on the contractual, regulatory or internal requirements.
The qualification pronouncement, or equivalent, associated with the producibility and with the
production system is the result of this analysis and validation activity.
5.2 Aim of the MIF and the justifications provided
The MIF is a result of the industrialization process, with the MIJF, which contains the results of the
justification of the elements described in the MIF, on the basis of the MIJP, but also the responses to the
production system qualification needs.
The aim of the MIF and its associated justifications is to guarantee the production, compliance and
reproducibility of the product (in accordance with the DDF), while providing the necessary traceability
with regard to the regulatory and contractual requirements.
The MIF and its associated justifications constitute the reference framework of the production process
in a given industrial context (risk analysis and the associated decision making) and with objectives in
terms of quality, costs, rate and lead times (cycles), capability and safety.
5.3 Structure of the documented information
The MIF and its associated justifications contain all the associated information on the product realized
with regard to the DDF.
The identification of the MIF should contain the identification of the product.
Depending on the organization of the company, the contractual requirements and the constraints
applying to the realized products, the MIF and its associated justifications may be structured into
different parts in order to meet the various external or internal demands more easily. This approach
ensures that only the necessary information is sent to the customer.
NOTE In this case, the goal consists of conserving the knowledge and know-how of the supplier, which can be
open to audit by the customer, but not transmissible.
For each item of documented information, this structure can be used to define the expected objective,
which is characterized by a type file.
EXAMPLE These type files include: the installation and inspection file (IIF) or assembly and inspection
file (AIF), the installation and inspection justification file (IIJF) or assembly and inspection justification file (AIJF),
the manufacturing choices justification file (MIJF), the installation choices justification file (ICJF) or the assembly
choices justification file (ACJF), etc.
The associated justifications may be delivered to an inspection authority or the customer, in accordance
with the terms of the contract.
5.4 Impacted stakeholders in the organization

process, and in particular in the elaboration of the constituent elements of the MIF and its associated

Figure 2 — Map of the stakeholders that contribute to the industrialization process
5.5 Recipients of the MIF and the associated justifications
The MIF (in part or in full) is intended for:
— production planners, for the aspects related to the operating procedure;
— procurement/purchasing, because it characterizes the raw materials, constituents and
subcontracted products;
— workshop operators, in order to apply the implementing provisions for the manufacturing,
inspection or test operations;
— production support departments (methods, maintenance, quality, etc.), in order to implement the
provisions for controlling and/or monitoring processes, tooling and means of testing and
production;
— the organization’s quality department, because it contains the necessary information for the
various reviews and to control the activities.
It could be made available for the customer for consultation, according to the terms of the contract.
The associated justifications (in part or in full) are intended for:
— the customer, when it is a contractual requirement;
— the organization itself, when required by the organization’s internal procedures, in particular as
proof during technical events, proof of the initial first article critical inspection (initial FACI), etc.;
— the regulatory authorities (pyrotechnical safety, electrical safety, confidentiality, etc.).
The conditions applying to the disclosure of manufacturing and inspection data may be subject to
special contractual provisions (intellectual property, know-how or other regulatory restrictions, etc.).
The customer and the supplier reach an agreement on a selection of data that is necessary and sufficient
to exercise their activities, and, in this regard, the contract specifies the information to be exchanged
and the modes of access.
6 Elaboration process of the MIF and the associated justifications
6.1 Data to be taken into account
In order to be able to carry out the MIF and the associated justifications elaboration process, it is
necessary to perform a precise analysis of the following input data:
— the DDF (technical constraints, imposed processes, results of the product FMECA, the key
characteristics, etc.);
— the requirements of the (need) technical specification [(N)TS] of the customer related to
producibility and reproducibility (control of the production system);
— programme-related requirements (rates, management plan, contractual and regulatory obligations,
technical specifications and standards, costs, requirements related to the quality management
system, configuration management, etc.);
— strategy and industrial constraints:
o lessons learned from the preceding industrializations (know-how of the company);
o taking into account of the constraints and relations with other industrialization programmes in
progress (inspection of common resources, etc.);
o means, skills, methods, instructions and procedures, manufacturing and inspection facilities
and tooling, etc.;
o manufacturing readiness level (MRL) and control of the manufacturing processes to
be implemented;
o capability to maintain the production system in an operational condition;
— procurement strategy and constraints, suppliers and available means (imposed suppliers, single-
sourcing, obsolescence management, export control, etc.);
— regulatory constraints pertaining to security, safety, the environment, health, etc.
The relative importance of each item of input data varies according to the kind of product.
6.2 Position in the execution logic
The elaboration logic of the MIF and its associated justifications needs programme-wide
synchronization that is consistent with the elaboration of the DDF at its different maturity levels [linked
to the milestones of the execution plan (see RG.Aero 000 41)]. This logic allows a gradual construction
of the demonstration of the producibility and reproducibility, between what is planned (DDF) and what
is realized (physical output of the MIF), while taking account of the enablers (production system,
support system) and the necessary stakeholders points of view of the that take part in the activities.
NOTE For details of the support system aspects, see RG.Aero 000 76.
This approach is incorporated in the various phases of the industrialization logic (Figure 3).

Figure 3 — Industrialization logic
The industrialization logic follows an iterative approach that is structured in phases and steps
corresponding to the expected MRLs:
— during the development of the industrialization, co-engineering (design/industrialization) enables
the industrial means of the production system to be deployed to be specified and planned;
— in phase 1 – step 1, the procurement of the means of production, the deployment and adjustment of
the production system, as the taking into account of the associated support system requirements
(including training), are realized. At the end of this period, the DDF of the product is imperatively
validated and the production system can demonstrate producibility;
NOTE Long procurement lead times can be initiated at the end of step 1.
— in phase 1 – step 2, samples are manufactured using processes representative of the serial
production processes. This realization allows to validate the producibility of the product and the
capability of the production system and the associated support system to realize the product;
— in phase 2, the serial production of the product is launched (reproducible product).
The optimization of the production system and its support system is sought in order to achieve the
expected production objectives;
— the last phase, during serial production, allows to ensure the maintenance and continual
improvement of the production system.
This elaboration is validated in successive reviews of the constituent elements of the MIF.
6.3 Improvement logic of the MIF
The following flowchart (Figure 4) shows the various steps of the elaboration of the MIF and its
associated justifications, from its initialization to its validation.
Figure 4 — Elaboration process for the MIF — Project perspective
The elaboration logic of the MIF and its associated justifications follow the industrialization logic.
Consequently, it is necessary to structure three aspects of the elaboration logic of the MIF:
— the strategy to be implemented: this first aspect related to steering needs the elaboration of an
industrialization plan that provides to all the resources working on the programme a coherent
vision of the necessary synchronization between the DDF, the MIF and the MIJF, and also between
the production activities. The definition of this implemented strategy is in general formally laid
down in an industrialization plan. The production plan (see RG.Aero 000 43) is usually launched in
parallel, in order to guarantee industrialization/production consistency. This strategy is updated
and fine-tuned during the phases/steps of the industrialization logic. The industrialization and/or
production plans are updated during the design phase in order to take account of design-
related events;
— the elements linked to the content of the MIF: this second aspect is related to the content of the MIF
and is built gradually, directly in line with the readiness level maturity of the various versions of
the DDF and the aspects related to the production system. This logic is described in 6.3;
— the justification elements of the MIF: this third aspect is related to the content of the MIJP and the
MIJF, which are prepared in parallel, and its construction is directly related to the maturity of the
various versions of the MIF.
In order to control each production elementary process, a file is established at each level of the
production breakdown structure where a constituent part is to be realized by taking account of
the interfaces.
7 Content of the MIF
7.1 Global overview of the MIF
Figure 5 shows a typical breakdown structure of the constitutive elements of an MIF, which are
described in detail in the following paragraphs. In addition to the hierarchical links, transverse
interactions exist between each element.
This typical breakdown structure is designed at a given article level (industrial scope), in correlation
with the breakdown structure of the DDF and according to the complexity of the product, the
contractual terms, etc.
Figure 5 — Typical breakdown structure of the elements of the MIF
The complexity of the constitutive elements of the MIF and its justifications may vary, depending on the
kind of product in question, on the one hand, and on the stage of elaboration of the
product (development, pre-series or serial production) on the other.
The content of the MIF takes account of “functions” lessons learned and of the structure of the available
information systems.
7.2 Detailed composition of the MIF
7.2.1 Manufacturing and inspection flowchart (MIFC)
The MIFC (see Table 1) is a graphic breakdown of the DDF from the perspective of industrialization that
is used to share and collectively understand the cycle of the product production process in order to
make sure that the contractual requirements are taken into account correctly.
Table 1 — Manufacturing and inspection flowchart

Input and opportunities:
Technical data:
•   product DDF: design office/design authority;
•   industrial requirements (production costs, reliability, cycle, constraints of the production scheme): programme team;
•   industrial policy: company (make or buy, internal standard, purchasing policy, quality policy, etc.);
•   normative (e.g. special processes) and regulatory environment;
•   contractual requirements: customer demands (e.g. industrial scheme).
Opportunities: contextual parameters/industrial environment (partnerships, etc.).
Transformations:
Following the thinking of the industrialization (compromise between requirements/capacities), the MIFC allows to view
the optimized sequence of the manufacturing steps (meeting the cost, quality and deadline objectives).
It allows to validate the consistency with the DDF, in particular with regard to the checkpoints and forms a link between
the definition and the chosen manufacturing process.
In the event of subcontracting, it constitutes fundamental input data for the teams in order to break down the
requirements in the associated documents.
Output and interfaces:
Flowchart that specifies the following for the different realization teams:
•   the chronology of the manufacturing steps with the references of the main documents, if necessary;
•   the logic of the steps and the characteristics (including the key characteristics) of the associated internal/external
inspections;
•   all the critical information on the sustainability of this manufacturing process.
And it also includes, in the MIFC or an associated document:
•   the “industrial breakdown” and the production breakdown structure (make or buy, imposed suppliers, etc.), including
the configuration items and the parameters (key characteristics, for example).
Formalization:
In the form of a “standardized” chronological synoptic/flowchart, with symbolic representations of the manufacturing
steps and the checkpoints/self-checks.
This synoptic can be broken down into several levels or several scopes, while totally covering the product.
Best practices:
•   it is produced together with the MIJP: it is implemented right from the detailed design phase as part of the co-
engineering process (managed during the successive project reviews): entry point of the IF;
•   it forms the link between production and the design offices (it is used as a link to manage reciprocal impacts in the
event of changes);
•   it is elaborated collaboratively by the various methods departments and forms part of the IF;
•   it is elaborated in accordance with the definition breakdown structure, in particular for technical change management
aims, while also taking the industrial constraints into account;
•   validation is reached during the co-signatory final industrial validation, e.g.: manufacturer, quality, designer, RAMS;
•   it is requested from subcontractors;
•   it is maintained when a change (in the definition, technical, organizational, etc.) so requires, as part of the updating of
the MIF;
•   in cases of multiple sources, there are several MIFCs.
At the start of industrialization, it is the risk analysis that identifies the processes to be monitored particularly closely in
order to realize the product (key characteristics, etc.).
The level of detail and formalization of the MIFC is defined according to the complexity of the process, the customer’s
requirements, etc. It may be limited to the manufacturing routine. By way of example, RC.Aero 003 40 may be consulted.
