of calendar days in a year by the process cycle time expressed in
calendar days. These are only opportunities to learn until the
feedback loop is closed at which point they become effective Cycles of
Learning.
Delivery performance: The ability of a business to deliver product or
service that meets customer requirements, against a specification for
delivery time. Delivery performance is measured as on time; in the
right quantities, meeting customer requirements. It is measured
against the customers' latest requests. Delivery performance cannot
be improved by quoting long lead times and turning down tough
business. Commonly, on-time delivery is measured as percent
achievement within a window of time that brackets the customer-
requested date and/or the business' committed date. This measurement
is often manipulated by rescheduling, not counting delinquencies (late
shipments), counting line items instead of all items required, and
many other approaches.
Determinism:
(See: "Deterministic.")
Deterministic: A process or subprocess is considered to be
deterministic if four key items are known within given ranges. They
are: the results, the steps and order of steps, the duration of the
steps, and the resources required. A process or subprocess is
considered to be non-deterministic if any of the above elements within
a given range are unknown; e.g., the process for making the same
product over and over again should be deterministic. The process for
"making" a super-collider is probably non-deterministic.
Driver: A person, methodology or tool that changes the course of
events by influencing actions in a desired direction.
Entitlement: The optimum performance level attainable by a business
using its existing resources. The existing resource may have to be
refocused and reallocated to achieve Entitlement.
Experience curve:
(See: "Learning curve.")
Feedback loop: A structured procedure, that may include a management
forcing function, where the lessons of a Cycle of Learning are
applied to improve a process.
Feedback: The information/decisions applied back into a process
(e.g., the applied lessons learned from a Cycle of Learning). The
information is used to maintain output within predetermined goals, or
to improve the process. Feedback is actually feed forward in time,
but feed back into the process.
FIFO:
Acronym for "First-In-First-Out".
