QUALITY MANAGEMENT
8.1 GENERAL
The key point in modern quality management (QM) is not only to control the final product, but the entire process as well. A fundamental approach to quality is the quality improvement circle. This can be seen as containing four steps: the preparing and planning, the realization of the product, checking of the results also in view of the user’s satisfaction, and finally reacting to that information with the purpose to improve further actions.
The quality of observing systems can be assessed by comparison of users’ requirements and ability of the systems to fulfil them. More details are given in Part II.


    1. QUALITY MANAGEMENT FRAMEWORK

XIV Congress decided, by adopting Resolution 27 (Cg-XIV) – Quality management, that WMO should work toward a Quality Management Framework (QMF) for NMSs that would eventually include and develop the following distinct though related elements:



  • WMO technical standards;

  • Quality management system(s) including quality control; and

  • Certification procedure(s).

The structure of the existing QMF corresponds to the following basic purposes of the WMO:



  • To ensure adequate uniformity and standardization in the practices and procedures used by National Meteorological Services;

  • To ensure quality of observational data since the effectiveness of any NMS depends on the quality of data and products exchanged through the WMO Systems;

  • To ensure overall availability of observational data for all purposes, especially for the numerical weather prediction.

As regards the GOS these purposes are realized through:



  • Extensive system of documented standards and recommended practices and procedures which shall, or should, be followed by Members. These are described in the Manual on the GOS, in the Guide on the GOS and in some other publications;

  • Different levels of quality control procedures of meteorological observations (the observing site, collecting centres, prior to transmission over GTS centres and GDPFS centres);

  • Variety of systems for monitoring of the availability of observational data (statistics concerning the availability of observational reports on a non-real-time basis, real-time monitoring on a global basis in leading centres, etc.);

  • Activities for training of personal operating different elements of the GOS (training courses, regional meteorological training centres, etc.).

The WMO QMF should enable the provision of early and continuing relevant advice to Members on developing their quality management system (QMS). The WMO QMF, in accordance with the EC-LVI statement, should focus on technical aspects of the operation of the NMSs.





    1. WMO TECHNICAL STANDARDS AS REFERENCE DOCUMENTATION

The procedures and practices described in the WMO Technical Regulations already provide the basis material for use as the reference material in national QMSs. This documentation contains also some quality requirements, quality control and quality assurance practices and procedures.





    1. QUALITY MANAGEMENT SYSTEM

According to the ISO 90001 terms and definitions, a quality management system (QMS) is a system to manage and control an organization with regard to quality. The idea of the ISO QMS is based on the widely known fact that the quality of the final product of the organization depends on the quality of the functioning of each of the links of the chain of processes.


A quality management system defines the specific procedures, processes and resources required to meet a specified standard. The ISO 9001 Standard defines the requirements for such a system.

The ultimate goal of a QMS is to encourage and support the continual improvement of the quality of the delivered services and products.


A QMS consists of a set of rules, procedures and practices that an organization decides to follow in order to achieve its objectives related to the quality of its products. In order to ensure the achievement of the quality objectives, it is essential that clear and unambiguous procedures are used for each specific task.
In the GOS it is necessary to specify more precisely the separate elements (processes) of the QMS for basic observational networks, and criteria for the control of their quality including the procedure for monitoring and, where applicable, the quality of processes (different functions) of observing systems. More attention should be given to guidance on how to manage observational networks of stations and observing subsystems.
The provision of good quality observational data is impossible without a quality management system. The appropriate QMS shall operate continuously at all points of the whole observing system, from planning and installation, through operations, maintenance and inspection, test and calibration, quality and performance monitoring, training and education, to data pre-processing, dissemination, processing and archiving; feedback and follow-up actions are inseparable parts of this chain.
General ISO 9001 requirements applicable on the GOS:

  1. Identification of the processes needed for the QMS;

  2. Determination of the sequence and interactions of these processes;

  3. Determination of the criteria and methods to ensure the operation and control of the processes;

  4. Provision of resources and information necessary to support the management and operation of the processes;

  5. Monitoring, measurement and analysis of the processes;

  6. Implementation of actions necessary to achieve planned results and continual improvement of the processes.

Further discussion on Quality Management can be found in the Guide to Meteorological Instruments and Methods of Observation (WMO-No. 8), Part III, Chapter 1.


Vocabulary:

Quality: Degree to which a set of inherent characteristics fulfils requirements.

Quality policy: Overall intentions and direction of an organization related to Quality, as formally expressed by management.

Quality Management: Coordinated activities to direct and control an organization with regard to quality

Quality Management System: Management tool to direct and control an organization with regard to Quality.

Quality Assurance: Part of Quality Management focused on providing confidence that quality requirements will be fulfilled.

Quality assurance includes all the planned and systematic activities implemented in a quality system so that quality requirements for a product or service will be fulfilled.



Quality Control: Part of Quality Management focused on fulfilling quality requirements.

Quality control includes all the operational techniques and activities used to fulfil requirements for quality.

10 The current limitation of WMO station number to 999 (also limited by BUFR descriptor 0 01 002, which has a data width of 10 bits) is a problem for a wide exchange of observations. More than 999 stations often exist in the area covered by a given WMO block number. Not all the observations available are currently disseminated on the GTS. To disseminate the observations from all the stations potentially available, the WMO station number should be expanded (that is a new descriptor defined and used).

11 To add a note for the relevant descriptor denoting latitude and longitude with reference to WGS 84.

12 To add a note for the existence of shielding and type of shielding applied and whether artificially ventilated or not.

13 To be standardized. France has defined a classification using values from 1 to 5. The NOAA/NCDC Climate Reference Stations use a similar classification system. It is recommended that CIMO develop guidelines for such classification, possibly in collaboration with ISO (TC146, SC5 meteorology).

14 If dew point temperature is directly measured by a sensor, the lower limit is to be used. If dew point is calculated from measurements of air temperature and relative humidity, a larger limit is recommended (taking into account the influence of the screen protecting the thermometer and hygrometer). A screen usually has different ‘system response time’ for air temperature and water vapour, and the combination of these two parameters may generate fast variations of dew point temperature, which are not representative of a sensor default, but are representative of the influence of the screen during fast variations of air temperature and relative humidity.

15 For ground temperature outside the interval (-0.2 °C +0.2 °C). Melting snow can generate isothermy, during which the limit should be 0 °C (to take into account the measurement uncertainty).

16 For relative humidity < 95% (to take into account the measurement uncertainty).

17 For 10-minute average wind speed during the period > 0.1 ms-1.

18 For 10-minute average wind speed during the period > 0.1 ms-1.
