ISO 9000 essentials
The ISO 9000 family of standards represents an international consensus on good quality management practices. It consists of standards and guidelines relating to quality management systems and related supporting standards.
ISO 9001:2000 is the standard that provides a set of standardized requirements for a quality management system, regardless of what the user organization does, its size, or whether it is in the private, or public sector. It is the only standard in the family against which organizations can be certified – although certification is not a compulsory requirement of the standard.
The other standards in the family cover specific aspects such as fundamentals and vocabulary, performance improvements, documentation, training, and financial and economic aspects.
Why an organization should implement ISO 9001:2000
Without satisfied customers, an organization is in peril! To keep customers satisfied, the organization needs to meet their requirements. The ISO 9001:2000 standard provides a tried and tested framework for taking a systematic approach to managing the organization's processes so that they consistently turn out product that satisfies customers' expectations.
How the ISO 9001:2000 model works
The requirements for a quality system have been standardized - but many organizations like to think of themselves as unique. So how does ISO 9001:2000 allow for the diversity of say, on the one hand, a "Mr. and Mrs." enterprise, and on the other, to a multinational manufacturing company with service components, or a public utility, or a government administration?
The answer is that ISO 9001:2000 lays down what requirements your quality system must meet, but does not dictate how they should be met in any particular organization. This leaves great scope and flexibility for implementation in different business sectors and business cultures, as well as in different national cultures.
Checking that it works
-
The standard requires the organization itself to audit its ISO 9001:2000-based quality system to verify that it is managing its processes effectively - or, to put it another way, to check that it is fully in control of its activities.
-
In addition, the organization may invite its clients to audit the quality system in order to give them confidence that the organization is capable of delivering products or services that will meet their requirements.
-
Lastly, the organization may engage the services of an independent quality system certification body to obtain an ISO 9001:2000 certificate of conformity. This last option has proved extremely popular in the market-place because of the perceived credibility of an independent assessment.
The organization may thus avoid multiple audits by its clients, or reduce the frequency or duration of client audits. The certificate can also serve as a business reference between the organization and potential clients, especially when supplier and client are new to each other, or far removed geographically, as in an export context.
Quality management principles
The following text is an integral reproduction of the content of the document "Quality Management Principles".
Introduction
This document introduces the eight quality management principles on which the quality management system standards of the revised ISO 9000:2000 series are based. These principles can be used by senior management as a framework to guide their organizations towards improved performance. The principles are derived from the collective experience and knowledge of the international experts who participate in ISO Technical Committee ISO/TC 176, Quality management and quality assurance, which is responsible for developing and maintaining the ISO 9000 standards.
The eight quality management principles are defined in ISO 9000:2000, Quality management systems Fundamentals and vocabulary, and in ISO 9004:2000, Quality management systems Guidelines for performance improvements.
This document gives the standardized descriptions of the principles as they appear in ISO 9000:2000 and ISO 9004:2000. In addition, it provides examples of the benefits derived from their use and of actions that managers typically take in applying the principles to improve their organizations' performance.
- Principle 1: Customer focus
- Principle 2: Leadership
- Principle 3: Involvement of people
- Principle 4: Process approach
- Principle 5: System approach to management
- Principle 6: Continual improvement

This document provides a general perspective on the quality management principles underlying the ISO 9000:2000 series. It gives an overview of these principles and shows how, collectively, they can form a basis for performance improvement and organizational excellence.
There are many different ways of applying these quality management principles. The nature of the organization and the specific challenges it faces will determine how to implement them. Many organizations will find it beneficial to set up quality management systems based on these principles.
Further information on the ISO 9000 standards is available from ISO's national member institutes or from the ISO Central Secretariat ISO 9000 enquiry service. Sales enquiries should also be directed to the ISO members or to the ISO Central Secretariat sales department.
ISO publishes the bimonthly ISO Management Systems, which provides updates on these families of standards and news on their implementation around the world. A Spanish-language edition is published by the Spanish national standards institute, AENOR.
Selection and use of the ISO 9000 family of standards
The ISO 9000 family of international quality management standards and guidelines has earned a global reputation as a basis for establishing effective and efficient quality management systems.
The need for international standards is very important as more organizations operate in the global economy by selling or buying products and services from sources outside their domestic market.
This e-brochure (online only, in this HTML version) has been developed by ISO Technical Committee ISO/TC 176, Quality management and quality assurance, which is responsible for developing and maintaining the ISO 9000 family. Supporting guideline standards and other documents are developed and updated on a continual basis to meet the needs and expectations of users and the market itself. This brochure provides a link to these guidelines and how you can use them to improve your quality management system.
This brochure provides a general perspective on the ISO 9000 family of standards. It is an overview of the standards and demonstrates how, collectively, they form a basis for continual improvement and business excellence.
ISO 9001 specifies the basic requirements for a quality management system (QMS) that an organization must fulfil to demonstrate its ability to consistently provide products (which include services) that enhance customer satisfaction and meet applicable statutory and regulatory requirements. The standard can be used for certification/registration and contractual purposes by organizations seeking recognition of their quality management system.
ISO 9001 has been organized in a user-friendly format with terms that are easily recognized by all business sectors.
You will obtain the greatest value by using the entire family of standards in an integrated manner. It is highly recommended that you use ISO 9000 to become familiar with the basic concepts and the language used before you adopt ISO 9001 to achieve a first level of performance. The practices described in ISO 9004 may then be implemented to make your quality management system more effective and efficient in achieving your business goals and objectives. The ISO 9001 and ISO 9004 standards have been written to enable you to relate them to other management systems (e.g. environmental), or to sector specific requirements (such as ISO/TS 16949 in the automotive industry) and to assist you in gaining recognition through national or regional award programmes

Auditing 'competence' and the 'effectiveness' of Action Taken
The following information is provided to guide auditors performing certification audits in understanding the ISO 9001 clause 6.2.2 requirements for 'competence' and 'effectiveness of actions taken', e.g. training.
To satisfy the competence/effectiveness requirements of ISO 9001, an organization will typically need to do several things:
- Identify what competencies are required by personnel performing work which affects quality
- Identify which personnel already performing the work have the required competencies
- Decide what additional competencies are required
- Decide how these additional competencies are to be obtained – training of personnel (external or internal), theoretical or practical training, hiring of new competent personnel, assignment of existing competent personnel to different work
- Train, hire or reassign personnel
- Review the effectiveness of actions taken to satisfy competence needs
- Periodically review competence of personnel
- An organization needs to identify what competencies are required by personnel performing work that affects quality.
Guidance:
The objective of the auditor should be to determine whether there is a systematic approach in place to identify these competencies and to verify that the approach is effective. The outcome of the process may be a list, register, database, human resources plan, competencies development plan, contract, project or product plan etc.
Discussions could initially be held with top management to ensure they understand the importance of identifying the competencies required. These may also be a potential source of information regarding new or changed activities or processes, which may lead to different competency requirements in the organization
A review of competencies might also be needed when a new tender or contract is being considered. Evidence of this could be found in related records. Competence requirements may be included in contract documents where the activities of subcontractors can have an impact on processes and/or product quality characteristics.
Auditors need to determine whether the organization has identified new or changed competence needs during surveillance audits. - Are competent people assigned to those work place activities necessary to control the quality characteristics of its processes and products?
Guidance
Verify that some form of evaluation process is in place to ensure that the competencies are appropriate to the organization's activities, and that the personnel selected as competent are demonstrating these competencies.
Also, the process should ensure that any deficiencies are being acted upon and the effectiveness of personnel is being measured.
Verify that the activities that affect quality are performed by persons selected as competent. Evidence may be obtained throughout the audit with an emphasis on those processes, activities, task and products where human intervention may have the greatest impact. The auditor may review job descriptions, testing or inspection activities, monitoring activities, records of management reviews, definition of responsibilities and authorities, nonconformity records, audit reports, customer complaints, processes validation records etc. - The organization should evaluate the effectiveness of the actions taken to satisfy the competence needs.
Guidance
The organization may use a number of techniques including role-play, peer review, observation, reviews of training and employment records and/or interviews (see ISO 19011, table two, for further examples). The appropriateness of a particular evaluation method will depend on many factors. For example, training records
could be viewed to verify that a training course had been successfully completed (but note, this alone would not provide evidence that the trainee is competent). However, this same method would not be acceptable to evaluate whether an auditor performed satisfactorily during an audit. Instead, this may require observation, peer review, interviews etc. The organization may need to demonstrate the attainment of competence of its personnel through a combination of education, training and/or work experience. - Maintenance of competence.
Guidance
The auditor needs to verify that some form of effective monitoring process is in place and being acted upon. Ways of doing this include a continuing professional development process (such as the one described in ISO 19011), regular appraisals of personnel and their performance, or the regular inspection, testing or auditing of product for which individuals or groups are responsible. Ongoing changes in competence requirements may indicate that an organization is proactive in maintaining personnel performance levels.

Kesultanan Palembang
Kuto Gawang Pada awal abad ke-17, Palembang menjadi pusat pemerintahan kerajaan yang bernuansa Islam dengan pendirinya Ki Gede ing Suro, bangsawan pelarian dari Kesultanan Demak akibat kemelut politik setelah mangkatnya Sultan Trenggana. Pada masa ini pusat pemerintahan di daerah sekitar Kelurahan 2-Ilir, di tempat yang sekarang merupakan kompleks PT Pupuk Sriwijaya. Secara alamiah lokasi keraton cukup strategis, dan secara teknis diperkuat oleh dinding tebal dari kayu unglen dan cerucup yang membentang antara Plaju dengan Pulau Kembaro, sebuah pulau kecil yang letaknya di tengah Sungai Musi. Keraton Palembang yang dibangunnya itu disebut Keraton Kuto Gawang yang bentuknya empat persegi panjang dibentengi dengan kayu besi dan kayu unglen yang tebalnya 30 x 30 cm/batangnya. Kota berbenteng yang di kemudian hari dikenal dengan nama Kuto Gawang ini mempunyai ukuran 290 Rijnlandsche roede (1093 meter) baik panjang maupun lebarnya. Tinggi dinding yang mengitarinya 24 kaki (7,25 meter). Orang-orang Tionghoa dan Portugis berdiam berseberangan yang terletak di tepi sungai Musi. Kota berbenteng ini sebagaimana dilukiskan pada tahun 1659 (Sketsa Joan van der Laen), menghadap ke arah Sungai Musi (ke selatan) dengan pintu masuknya melalui Sungai Rengas. Di sebelah timurnya berbatasan dengan Sungai Taligawe, dan di sebelah baratnya ber¬batasan dengan Sungai Buah. Dalam gambar sketsa tahun 1659 tampak Sungai Taligawe, Sungai Rengas, dan Sungai Buah tampak terus ke arah utara dan satu sama lain tidak bersambung. Sebagai batas kota sisi utara adalah pagar dari kayu besi dan kayu unglen. Di tengah benteng keraton tampak berdiri megah bangunan keraton yang letaknya di sebelah barat Sungai Rengas. Benteng keraton mempunyai tiga buah baluarti (bastion) yang dibuat dari konstruksi batu. Orang-orang asing ditempatkan/ber¬mukim di sebe¬rang sungai sisi selatan Musi, di sebelah barat muara sungai Komering (sekarang daerah Seberang Ulu, Plaju).
Beringin Janggut Setelah Keraton Kuto Gawang dihancurkan VOC tahun 1659, oleh Susuhunan Abdurrahman pusat pemerintahan dipindahkan ke Beringin Janggut yang letaknya di sekitar kawasan Mesjid Lama (Jl. Segaran). Sayang data tertulis maupun gambar sketsa mengenai keberadaan, bentuk, dan ukuran keraton ini hingga saat ini tidak ada. Daerah sekitar Keraton Beringin Janggut diba¬tasi oleh sungai-sungai yang saling berhubungan. Kawasan keraton di¬batasi oleh Sungai Musi di selatan, Sungai Tengkuruk di sebelah barat, Sungai Penedan di sebelah utara, dan Sungai Rendang/Sungai Karang Waru di sebelah timur. Sungai Penedan merupakan sebuah kanal yang menghubungkan Sungai Kemenduran, Sungai Kapuran, dan Sungai Kebon Duku. Karena sungai-sungai ini saling berhubungan, penduduk yang mengadakan perjalanan dari Sungai Rendang ke Sungai Tengkuruk, tidak lagi harus keluar melalui Sungai Musi. Dari petunjuk ini dapat diperoleh gambaran bahwa aktivitas sehari-hari pada masa itu telah berlang¬sung di darat agak jauh dari Sungai Musi.
Kuto Tengkuruk Kawasan inti Keraton Kesultanan Palembang-Darussalam pada masa pemerintahan Sultan Mahmud Badaruddin I luasnya sekitar 50 hektar dengan batas-batas di sebelah utara Sungai Kapuran, di sebelah timur berbatasan dengan Sungai Tengkuruk (sekarang menjadi Jl. Jenderal Soedirman), di sebelah selatan berbatasan dengan Sungai Musi, dan di sebelah barat berbatasan dengan Sungai Sekanak. Pada awalnya di areal tanah yang luasnya sekitar 50 hektar ini hanya terdapat bangunan Kuto Batu atau Kuto Tengkuruk dan Masjid Agung dengan sebuah menara yang atapnya berbentuk kubah. Pada saat ini batas kota Palembang kira-kira di sebelah timur berbatasan dengan Kompleks PT. Pusri, di sebelah selatan berbatasan dengan Sungai Musi, di sebelah barat berbatasan dengan Sungai Lambidaro (36 Ilir), dan di sebelah utara hingga sekitar Pasar Cinde.
Kuto Besak Pada masa pemerintahan Sultan Muhamad Bahaudin (1776-1803), dibangun Keraton Kuto Besak. Letaknya di sebelah barat Keraton Kuto Tengkuruk. Kuto ini mempunyai ukuran panjang 288,75 meter, lebar 183,75 meter, tinggi 9,99 meter, dan tebal dinding 1,99 meter membujur arah barat-timur (hulu-hilir Musi). Di setiap sudutnya terdapat bastion. Bastion yang terletak di sudut baratlaut bentuknya berbeda dengan tiga bastion lain, sama seperti pada bastion yang sering ditemukan pada benteng-benteng lain di Indonesia. Justru ketiga bastion yang sama itu merupakan ciri khas bastion Benteng Kuto Besak. Di sisi timur, selatan, dan barat terdapat pintu masuk benteng. Pintu gerbang utama yang disebut lawang kuto terletak di sisi sebelah selatan menghadap ke Sungai Musi. Pintu masuk lainnya yang disebut lawang buratan jumlahnya ada dua, tetapi yang masih tersisa hanya sebuah di sisi barat. Perang Palembang 1821 dan dibubarkannya institusi Kesultanan pada 7 Oktober 1823, bangunan Kuto Tengkuruk diratakan dengan tanah. Di atas runtuhan Kuto Tengkuruk, atas perintah van Sevenhoven kemudian dibangun rumah Regeering Commissaris yang sekarang menjadi Museum Sultan Mahmud Badaruddin II
