Work Breakdown Structure (WBS) - Elements Identification
Rationale
A WBS can be comprised of a large number of work packages, activities, services or configuration elements as the case may be. These must provide the ability to be acquired, manufactured, stored, uniquely itentified, managed and audited during the development and maintenance of the system, product or service. The most popular identification method is based on hierarchical identification as follows:
There are a number of similar methods e.g.:
-
NATO Numbering System;
-
SDLC Phase Numbering System;
-
US Navy Identification Number;
A unique identifier (UID) is a numeric or alphanumeric string that is associated with a single entity within a given system. UIDs make it possible to address that entity, so that it can be accessed and interacted with. Here are a few examples of UIDs:
-
A Uniform Resource Identifier (URI) is a unique identifier that makes content addressable on the Internet by uniquely targeting items, such as text, video, images and applications.
-
A Uniform Resource Locator (URL) is a particular type of URI that targets Web pages so that when a browser requests them, they can be found and served to users.
-
A Universal Unique Identifier (UUID) is a 128-bit number used to uniquely identify some object or entity on the Internet.
-
A global unique identifier (GUID) is a number that Microsoft programming generates to create a unique identity for an entity such as a Word document.
-
A bank identifier code (BIC) is a unique identifier for a specific financial institution.
-
A unique device identifier (UDID) is a 40-character string assigned to certain Apple devices including theiPhone, iPad, and iPod Touch.
-
An service set identifier (SSID) is a sequence of characters that uniquely names a wireless local area network (WLAN).
-
A national provider identifier (NPI) is a unique ten-digit identification number required by HIPAA for all health care providers in the United States.
