AAT ICAS training and development guidelines

ICAS standards documents for an effective version are developed for use by specialists and are not necessarily intended as general training documents. however AAT may develop various training documents and ICAS resources, and may review the organization of ICAS standards and resources documents with regard to an effective version of ICAS. please see AAT ICAS 2036 for additional ICAS materials.

principles of training for ICAS

a fundamental principle of ICAS is applicability of use. learning and using a new or emerging system of measure calls for consideration of certain human factors issues. the use of a system of measure can raise issues of user focus, and calls for the attentive and diligent application of various technical literacies. ICAS is not in itself a source of error or confusion. nor are other systems of measure categorically free of error or confusion. for any ICAS development it is important to determine who will be using an ICAS application and for what purposes. uses of ICAS scales should be managed to ensure applicable and responsible use within appropriate parameters of fault tolerance.

ICAS standards are designed to reduce the effect of certain issues on the measurement of time that relate to the integration of ICAS with other systems of time measurement. at the same time ICAS offers users some methods by which the processing or use of time data may be simplified. users should however understand that scale differentials in the comparison of measures among systems may be numerical and/or unitary.

• learning to use ICAS relative other standards for measuring time is similar to learning how time is expressed in a second language.
• taken together ICAS features and specifications can simplify the design, maintenance, and use of chronological applications.

determining ICAS training needs

most uses of time or date scales involve only a small subset of the chronological system (or systems) within which they are applied. this is true for traditional scales of date and time as well as for emerging uniform or metric scales. yet current measures of coordinated universal time (UTC) introduce capabilities for the accurate measurement of a main unit of 1 day that is not subject to variation in the rotation of the Earth. because the set of ICAS features represents an exceptional opportunity for an upgrade to uniform scales of calendar and clock, a proactive implementation should be attainable given current capabilities for development.

yet implementations of ICAS depend on the ICAS-readiness of organizations and users. the reinforcement of scale knowledge is a factor in the training and use of calendars and clocks, and ICAS users should be alert to the continual reinforcement of traditional scales of date and time throughout society. those considering ICAS metrication should be clear about the methods and strategies for implementing ICAS scales, and ensure that ICAS training and use references support the reinforcement of knowledge about ICAS scales. as ICAS standards continue to develop in support of a focus on usable design, licensees also need to be prepared to adapt to any changes in an effective version of ICAS.

organizations considering the use of ICAS should consider a qualified metrication study of the planning and development issues involved in using a new system of measure. organizations using ICAS should also prepare a metrication policy statement outlining how ICAS and other systems of measure will be used.

ICAS training can be designed with regard to particular uses or configurations of use. the scope of training needs for the use of ICAS measures can range from those concerning uses restricted to certain uses of time data, to those concerning general uses concurrent among other systems of time measure. for example, the scope of training for the use of a Uniform Calendar to process data that is not daygroup-dependent or daygroup-sensitive may be narrower than the scope of training for uses involving daygroup-dependence or daygroup-sensitivity across different daygroup scales.

organizations can train for the use of particular configurations of ICAS measures, and should thus determine particular ICAS training needs. training may focus on factors that bear on the practical use and factors of calculation among uniform and traditional systems of measure.

users of ICAS should know and understand practical issues bearing on ICAS use. training needs for ICAS users include: learning the schemes, names, and terms for ICAS units; learning the usage of ICAS units; understanding the relationships among ICAS and other systems of measure; and mastery of task or use-oriented ICAS methods or applications for particular purposes. users should also be able to readily express metric clock times in terms of both the clock units (generally to 2 numerical places for major, minor, and subminor clock units) for a dial, or in terms of the decitriad expression (in groups of 3 numerical places of a clock time).

developers of ICAS applications and systems and managers of ICAS licensees should also know and understand all standards documents for an effective ICAS standard.

for any particular use of ICAS, a reference document designating a particular configuration or mode of use should be readily available for any designated user. developers should also consider that reference information can be integrated into a particular method or application.
