Advanced Product Quality Planning (APQP) is a structured method for defining and executing the actions necessary to ensure a product satisfies the customer along with cost and time. APQP is required of all vehicle, system, subsystem and component manufacturing locations.
1.2 Goal
The goal of APQP is to facilitate communication with all persons involved in a programme and ensure that all required steps are completed on time, at acceptable cost and quality levels.
1.3 Purpose
The purpose of this guideline is to establish:
Common APQP expectations for all M&M activities.
Common APQP process metrics.
Common APQP deliverables.
A common programme status-reporting format.
Lead and Support roles and responsibilities for each APQP Element.
1.4 Approach
APQP emphasise on Up-front planning, First three part of the P-D-C-A cycle are devoted to up-front product quality planning through product / Process Validation. The Act of implementation, the fourth part is the stage where the importance of evaluating the output serves two functions; to determine if customers are satisfied, and to support the pursuit of continuous improvement.
This guideline focuses on 23 key APQP elements. Definitions, expectations, and deliverables for these elements are identified in Section 5.0 APQP Element Description of this guideline. The status for these disciplines is summarized on the APQP Status Report. This guideline provides a management tool for follow-up and timely completion of all 23 APQP Elements.
1.5 Applicability
APQP status reporting is a requirement of all M&M activities and must be applied to the following:
New Product launch/ relaunch.
Changed/ modified product launch.
Launch of a new manufacturing site.
Significant process changes (new facilities/ toolings).
High impact suppliers.
Carry over issues.
Part Submission Warrant (PSW) requirement as per the MQS Mahindra Production Part Approval Process Manual.
2.0 APQP Fundamentals
2.1 Teams
The first step in the Advanced Product Quality Planning Process is to assign lead responsibility for every APQP Element. This leader establishes a cross-functional team to complete the element requirements on time. Effective Product Quality Planning requires a cross-functional team including representatives from Product Development, Manufacturing Engineering, Manufacturing Plants, Purchasing, Quality, Field Service, Sales, Suppliers, and Customers, as appropriate.
2.2 Elements
This guideline focuses on 23 Key APQP disciplines, identified as APQP elements. These elements, when summarized and reported, communicate the quality planning status of a programme.
2.3 Adjustments
If the programme is considered to be low risk, the APQP leader may skip certain APQP elements. For example, if the product is carry-over with minor changes, existing control plans can be used and/ or packaging evaluations may not be required. The cross-functional team must agree to all deviations from the APQP process. If the team agrees that an element is not required, the function should write “N/A” for “not applicable” in the remarks section of the APQP Status Report (Annexure 1).
2.4 Roles & Responsibilities
The APQP Lead/Support Responsibilities are documented in Section 5.0 APQP Element Description, of this guideline.
2.5 APQP Elements in MPDS
The alignment of APQP elements is done using the timing plan of the Mahindra Product Development System (MPDS).

3.0 The APQP Status Report
3.1 Purpose
The APQP Status Report summarises the status for the 23 APQP elements. The status report facilitates communication between Product Development, Manufacturing Engineering, Manufacturing Plants etc. It also provides a dated record that future programmes for reference.
3.2 Status Reporting Responsibility
For each of the 23 elements, there is a lead responsibility defined. This lead function obtains the necessary input/support from other affected functions and consolidates it into a G/Y/R (Green/Yellow/Red) status (per element) on the APQP status report form.(MQS/APQP/F01)
Reporting Requirements
The Project Team consolidates the APQP status report and present summary to senior management at all major Programme Reviews/ Gateways. Action plan is prepared for all Yellow & Red status.
Ratings and Assessment
4.1 G Y R Status
Green-Yellow-Red status communicates the progress toward the successful project completion of elements by the program need date. Program need date is the last possible date an element can be completed and not adversely affect quality, cost or timing of the program. The “GYR Status” column of the report shows the assessment for each element.Definitions/Risk factors for Red, Yellow, and Green are listed in the table below.
Risk
Colour
Definition
High
Red
Target dates and/or elements are at risk. A recovery Action Plan is not available and/or implemented, or the Action Plan does not achieve program targets. Late on time.
Moderate
Yellow
Target dates and/or elements are at risk, but a recovery Action Plan has been developed to achieve program targets, and has been approved by the appropriate Project Team. Target date can be met with management support.
Low
Green
Target dates and elements are on track and meeting objectives.
Each element shall be supported by relevant documented evidence like reports, circular, filled format, quality documents, scanned signoff copy etc. For this purpose MQS & PQO recommends the use of appropriate softwares like Excel, Word, Power point, MS Project, etc with hyperlinks to the document.
Any item once become red will remain red & Yellow/Green will be superimposed appropriately to show latest status.
4.2 The 8 Focus Elements :
For all 23 elements, quality expectations are defined in this Guideline. Out of the 23 elements, the following 8 elements are considered as Focus Elements :
Design FMEA
Design Verification Plan
Prototype Build Control Plan
Manufacturing Process Flow Chart
Process FMEA
Pre-Launch Control Plan
Operator Process Instructions
Production Control Plan
These elements when completed with Quality and On Time lay the foundation for Programme success.
The 8 Focus Elements are assessed for Quality of Event using Focus Element Rating Checklist.
4.3 Status Report Descriptions :
Build Level : Indicates the level of Build such as Engineering Prototype, Verification Prototype, Production Trial Run, Job # 1, etc.
PIST : Percentage of Inspection points that satisfy Specified Tolerance (all points).
PIPC : Percentage of Indices which are Process Capable (Percentage of Critical & Significant Characteristics with Pp & Ppk greater than or equal to 1.67 for the pre-production phase and Cp and Cpk greater than or equal to 1.33 for production phase).
SC & CC (Special Characteristics) : All products and processes have features described by characteristics which are important and need to be controlled. However, some characteristics called special characteristics require extra efforts to minimise the risk of potential adverse consequences.
Special Characteristics consist of –
1. Critical Characteristics are those product or process requirements that affect compliance with government regulation or safe vehicle/ product function AND which require special actions/ controls.
Product or process requirements can include dimension, specification, tests, processes, assembly sequences, tooling, joints, torques, welds, attatchments, component usage etc.
Symbol : Severity Rating : 9 or 10 for any occurrence rating.
2. Significant Characteristics are those product, process, and/ or test requirements which are important for customer satisfaction AND for which Quality Planning actions must be summarised on a Control Plan.
Symbol : Severity Rating : 5 to 8 Occurrence Rating : 5 and above

5Design Verification Plan &Report
The Design Verification Plan & Report (DVP&R) is a document listing the engineering evaluations, tests, and reports required to establish a design fit for use in the intended environment and meets the customer driven objectives and the intent with which the product / process was designed. The design verification plan has a correlation with the Customer Input Requirement.
The DVP&R is a team approach
Identification of specific tests, methods, equipment, acceptance criteria, sample sizes, design level and timing must be contained in the DVP&R.
Tests must include variation within tolerance on team selected product characteristics.
The Design Verification must include:
Test requirements for design, material, or manufacturing process that apply to the production trial.
Tests, which address for the customer usage profile and duty cycle.
Tests which address the useful life of the product.
Tests which address the effects of the external environment (climate, road surface conditions etc)
Tests which address the effects of physical interfaces between components or systems.
