3.1

classification

category that the event (3.5) falls into

3.2

continual improvement

recurring activity to enhance performance (3.15)

Note 1 to entry: The process (3.16) of establishing objectives (3.13) and finding opportunities for improvement is a continual process through the use of audit findings and audit conclusions, analysis of data, management reviews or other means and generally leads to corrective action or preventive action.

Note 2 to entry: The nature of the activity can differ between cycles of recurrence.

[SOURCE:ISO 9000: 2015, 3.3.2, modified — Note 2 to entry replaced.]

3.3

documented information

information required to be controlled and maintained by an organization (3.14) and the medium on which it is contained

Note 1 to entry: Documented information can be in any format and media and from any source.

3.4

effectiveness

extent to which planned activities are realized and planned results are achieved

3.5

event

situation where a behaviour deviates from the normal

Note 1 to entry: An event can be one or more occurrences, and can have several causes.

Note 2 to entry: An event can consist of something not happening.

Note 3 to entry: An event can sometimes be referred to as an “incident” or “accident”.

Note 4 to entry: An event without consequences can also be referred to as a “near miss”, “incident”, “near hit” or “close call”.

Note 5 to entry: For the purposes of this document, “normal” refers to what is expected.

3.6

event detection

recognition of event indicator (3.9) and/or information about a new situation

3.7

event detection process

EDP

set of interrelated or interacting activities which transforms inputs [data or information on an actual or suspected event (3.5) ] into outputs [to support the water utility’s (3.19) operational activities]

3.8

event identification table

EIT

table developed by the organization (3.14) that contains examples of proven connections between changes in water measurements and possible causation types

3.9

event indicator

signal to the water utility or one or more stakeholders (3.18) that an event (3.5) can have occurred with the potential to cause a significant deviation in the users' expectations of service performance (3.15)

Note 1 to entry: The signal can exist yet remain unobserved for a period.

3.10

influence matrix table

IMT

table developed by the water utility (3.19) that contains suspected connections between event indicators (3.9) and performance measurements (3.11) based on scientific knowledge and water industry experience

3.11

measurement

process (3.16) to determine a value

3.12

monitoring

determining the status of a system, a process (3.16) or an activity

Note 1 to entry: To determine the status there can be a need to check, supervise or critically observe.

3.13

objective

result to be achieved

Note 1 to entry: An objective can be strategic, tactical or operational.

Note 2 to entry: Objectives can relate to different disciplines (such as finance, health and safety, and environmental goals) and can apply at different levels [such as strategic, organization-wide, project, product and process (3.16) ].

Note 3 to entry: An objective can be expressed in other ways, for example as an intended outcome, a purpose, an operational criterion, an event detection objective or by the use of other words with similar meaning (e.g. aim, goal or target).

Note 4 to entry: In the context of an event detection system, event detection objectives are set by the water utility (3.19) , consistent with the event detection management policy, to achieve specific results.

3.14

organization

person or group of people that has its own functions with responsibilities, authorities and relationships to achieve its objectives (3.13)

Note 1 to entry: The concept of organization includes, but is not limited to, sole-trader, company, corporation, firm, enterprise, authority, partnership, association, charity or institution, or part or combination thereof, whether incorporated or not, public or private.

Note 2 to entry: For the purposes of this document the organization responsible for event detection (3.6) will usually be part of a wider organization [the water utility (3.19) responsible for the provision of drinking water/wastewater services].

3.15

performance

measurable result

Note 1 to entry: Performance can relate either to quantitative or qualitative findings.

Note 2 to entry: Performance can relate to the management of activities, processes (3.16) , products (including services), systems or organizations (3.14) .

3.16

process

set of interrelated or interacting activities that use inputs to deliver an intended result

Note 1 to entry: Whether the “intended result” of a process is called an output, product or service depends on the context of the reference.

Note 2 to entry: Inputs to a process are generally the outputs of other processes and outputs of a process are generally the inputs to other processes.

Note 3 to entry: Two or more interrelated and interacting processes in series can also be referred to as a process.

Note 4 to entry: Processes in an organization (3.14) are generally planned and carried out under controlled conditions to add value.

Note 5 to entry: A process where the conformity of the resulting output cannot be readily or economically validated is frequently referred to as a “special process”.

3.17

risk

combination of the likelihood of a hazardous event and the severity of consequences, if the hazard occurs in the drinking water system or wastewater system

Note 1 to entry: Risk is often characterized by reference to potential events (3.5) and consequences or a combination of these.

Note 2 to entry: The English term “likelihood” does not have a direct equivalent in some languages; instead, the equivalent of the term “probability” is often used. However, in English, “probability” is often narrowly interpreted as a mathematical term. Therefore, in risk management terminology, “likelihood” is used with the intent that it has the same broad interpretation as the term “probability” has in many languages other than English.

Note 3 to entry: Risk can also be defined as the effect of uncertainty on objectives (3.13) ここで, uncertainty is the state, even partial, of deficiency of information related to understanding or knowledge of an event (3.5) , its consequence or likelihood.

3.18

stakeholder

interested party

person or organization (3.14) that can affect, be affected by or perceive itself to be affected by a decision or activity

Note 1 to entry: Stakeholders will typically have an interest in the performance (3.15) or success of an organization.

Note 2 to entry: For the application of this document, environment is considered as a specific stakeholder.

3.19

water utility

whole set of organization (3.14) , processes (3.16) , activities, means and resources necessary for abstracting, treating, distributing or supplying drinking water, for collecting, conveying, treating, disposing of and reusing wastewater or for the control, collection, storage, transport and use or disposal of stormwater and for providing the associated services

Note 2 to entry: Drinking water utility addresses a utility dealing only with drinking water; wastewater utility addresses a utility dealing only with wastewater; stormwater utility addresses a utility dealing only with stormwater.

Note 3 to entry: When it is not necessary or it is difficult to make a distinction between responsible body and operator, the term “water utility” covers both.

Note 4 to entry: In common English, “water service” can be used as a synonym for “water utility”, but this document does not recommend using the term in this way.
