Foreword This ETSI Guide (EG) has been produced by ETSI User Group (USER). Introduction A good standard should meet the following objectives: Guarantee a full
17、inter-working between different products or services that conform to that standard. Guarantee the safety of products and services for users. Be simple and worthwhile to implement. Be user friendly without conflicting options. Allow upward compatibility with products and services conforming to former
18、 standards. These objectives relate to the whole content of a standardization project including the process. In achieving these objectives three main issues relating to User requirements need consideration: How TC experts obtain information from Users on their requirements. How users can formulate t
19、heir inputs in an appropriate way such as to allow them to be properly taken account of by the standard makers. How the standardization progress can be monitored from a users point of view. ETSI ETSI EG 201 219 V1.3.1 (2006-03) 5 1 Scope The present document gives guidance to a Technical committee a
20、nd any other Technical body on how user requirements are to be taken into account during a standardization process. It is applicable to all stages of a standardization process but especially to those parts of the process that have a direct impact on satisfying the generic requirements listed in clau

27、6-03) 6 3 Definitions and abbreviations 3.1 Definitions For the purposes of the present document, the following terms and definitions apply: business user: user using telecommunication product/services for his/her trade business or profession involved with commercial or public service organizations
28、consumer: person or group of persons using electronic telecommunication products/services for purposes outside his/her trade, business or profession NOTE: Such persons are often referred to as Residential Subscribers. dialogue: interaction between a user and a system to achieve a particular goal EXA
29、MPLE: Communication with another end user. end user: business user or consumer usually without any technical knowledge of telecommunications but using terminals to utilize telecommunications services interconnection: physical and logical linking of telecommunication networks allowing users of one or
30、ganization to communicate with users of another organization or to access services provided by another organization interface: common boundary between two associated systems NOTE: See ITU-T Recommendation I.112 8, definition 408. interoperability: capability to ensure the whole set of operations act
31、ivated when an end-user asks for a service across a mixed environment of different equipment, networks, services including usage services, from different manufacturers and/or providers NOTE: Interoperability addresses the different levels: equipment interoperability (terminal, server), protocol inte
32、roperability (interconnection), service interoperability (interworking). interworking: interactions between networks, between systems or between parts thereof, with the aim of providing a functional entity capable of supporting endto-end communication NOTE: See ITU-T Recommendation I.510 9. IT see c
33、lause 6.5. the development of concepts such as “Virtual Home Environment“ is expected to help to fulfill this requirement. 6.3 Child safety issues Children defined as “persons under 18 years“ are becoming an increasingly significant subset of the consumer category utilizing advanced computing and co
34、mmunication services. There is the need to ensure that telecommunication products and services are safe for all users, children included. Moreover, there is the need to ensure a minimum quality of products and services used by children and that consumers can distinguish between products/services com
35、plying with minimum safety and quality standards and those that do not. 6.4 Comprehensible standards It is crucial that users understand what the advantage are, in general, of buying products and services conforming to formal standards and more specifically for a given product or service what the re
36、levant standards ensure. Since most standards contain technical statements that the common users are unable to understand, they should include, as an annex, a notice explaining the benefits they are providing to the users, as it is recommended for ITU-T Recommendations. 6.5 Consistency of user inter
37、face Systems should have consistent user interface. It is especially important that the methods of processing, storing and accessing systems are consistent for a user. NOTE: A consistent user interface can be achieved by different methods. Three examples are the following: - All components of the us
38、er interface are uniform. - The user interface adapts to the user, so that the user always meets a personalized uniform interface. - Development of concepts such as “Virtual Home Environment“. 6.6 Cost transparency Where standards are involved in presentation of cost information as for example at po
39、int of sale, these standards should provide for transparency regarding all costs involved and presented in a standardized way to clearly separate initial costs i.e. purchase of equipment and secondary costs i.e. subscription, setting up and operation and disconnection. ETSI ETSI EG 201 219 V1.3.1 (2
40、006-03) 11NOTE: Cost transparency is of particular importance for services when interworking on networks or when using on-line services such as directory services and short message services. 6.7 Ease of use All telecommunication products and services should be easy to use for all intended user categ
41、ories stated in the scope of a standard applicable to such products and services. Ergonomic aspects of hardware, software, services and support as given in ISO 9241-10 1, ISO 13407 3 and ISO 9241 (all parts) 4 should always be taken into account and any existing standards applied. Display of dialogu
42、e elements for intended users to facilitate choice or editing of items generated by a system or service should be incorporated where considered necessary. Goals for ease of use (usability statements) should be developed based upon ISO 9241-11 Guidance of Usability 2. These could be based upon measur
43、ements in terms of performance (time taken by users to complete a predetermined task, error numbers and service satisfaction etc). 6.8 Environmental issues Standards should provide evidence that environmental issues such as power consumption have been addressed with the objective of achieving a clea
44、n life-cycle from initial design to final disposal of a system/product. Any potential environmental risks need analysis so as to exclude or minimize such risks with a result indicated to potential users. A standardized way of risk analysis should be used and if not available the methodology used in
45、the standard identified with results made available to potential users. 6.9 Error tolerance and system stability Taking into account the functionality of a system/service the standard should address potential problems likely to be faced by targeted user categories and allow for solutions designed to
46、 provide help. The scope of the standard should clearly indicate for what user categories the system/service is targeted. The system should tolerate error in operation by users and be forgiving by the provision of informative error messages designed to lead users forward. The system should remain st
47、able in circumstances where users attempt access to services which cannot be delivered or make choices that are redundant. 6.10 Explorability The system should allow for provision of facilities to allow users to discover its functions. 6.11 Health and safety issues All health and safety issue should
48、 be taken into account and included within the risk assessment studies. Any relevant existing standards should be referenced and included. NOTE: ETSI TC Safety should be consulted on all health and safety issues. 6.12 Multi-cultural and multi-lingual aspects Development of any telecommunication stan
49、dard should take account of global use and hence consider multicultural and multilinguistic aspects of in-service use. Where relevant the use of UNICODE should be considered. ETSI ETSI EG 201 219 V1.3.1 (2006-03) 126.13 Provision of system/service information The standard should allow for provision of system and/or service information documentation to include: Functionality provided by system/service. Compliance/non-compliance with ITU/ETSI standards. Targeted user categories. System status information (e.g.
