内容简介：Guideline to the Supplier Quality Assurance Plan
during the development phase in the project
1 Introduction
1.1 Abstract
This document describes the general definitions, purposes, requirements and expectations
for the Ericsson Supplier Quality Assurance Plan (SQAP). This tool is used during the
development phase of a project prior to the ramp-up of custom parts and assemblies.
1.2 Application
This document should be applied by all direct Ericsson BT suppliers that provide custom
parts and assemblies. It shall also serve as a general guideline for quality assurance
requirements placed on suppliers by the R&D Procured Material Quality Assurance
(PMQA) organisation.
1.3 Purpose
The purpose of this document is to:
· describe the PMQA organisation
· explain Ericsson Quality Requirements
· explain how a typical high-volume project is managed within Ericsson BT concerning
the requirements on the Ericsson procurement department and the suppliers
· explain how the Supplier Quality Assurance Plan (SQAP) will help the supplier fulfil
the quality requirements
· explain the SQAP submission process and requirements
· explain the expectations of each SQAP requirement, and provide examples for each
step.
1.4 Reading suggestions
The reader who wants a quick summary can read chapter 1.
The interested reader who wants an overview of Ericsson Quality Requirements for the
suppliers can read chapters 1, 3 and 4. For a more thorough insight, please also read chapter
6.
2.1 The Procured Material Quality Assurance Organisation
The Ericsson Procured Material Quality Assurance (PMQA) is a world-wide organisation
whose purpose is to assure quality in supplier processes in an overall effort to provide
design conforming and cost effective parts/assemblies to Ericsson production facilities.
The PMQA organisation is divided into three parts:
The R&D organisation Responsible for securing the prototype and
volume production for new designs. Sufficient
actions should be done to assure that components
arriving to Ericsson production facilities
will conform to specifications with a high yield
in a cost effective way (see chapter 2.2).
The factory organisation Responsible for:
a) Incoming inspection
b) Component failure issues
c) Supplier development
d) Upholding and verifying new capacity for
components in volume production. Sufficient
actions should be done to assure that
components arriving to Ericsson production
facilities will conform to specifications with
a high yield in a cost effective way.
International Procurement Operations
(IPO)
Responsible for aiding the Procured Material
Quality Engineers (PMQEs) during supplier
visits and evaluations in the vicinity of each
respective IPO. Can also follow up issues/
findings for the PMQEs.
2.2 The PMQA Organisation within Research and Development
The Ericsson R&D PMQA is the part of PMQA which takes care of the first stage of a
component's life cycle. Since the choice of design and suppliers has a great impact on the
final quality of supplied components to Ericsson factories there is a multitude of tasks to be
done. Ericsson has identified four processes:
1. Securing the Supplier:
a) The evaluation process of potential suppliers' sites (one approval/site).
2. Securing the Product:
a) Ensure that Ericsson's specifications are clear and unambiguous to all suppliers and
all parts of Ericsson
b) Implement test methods
c) Correlate measurement methods
d) Training and implementation of cosmetic defect levels
e) Define critical dimensions.
3. Securing the Supplier's Processes with respect to:
a) Quality
b) Capacity.
4. Hand-over to the factory PMQA organisation:
a) Relevant documents
b) A capacity build-up report.
