Software Project Management

Notes The use of measurement is common. We use measurements in everyday life to do such things as
weigh ourselves in the morning or when we check the time of day or the distance we have
traveled in our car. Measurements are used extensively in most areas of production and
manufacturing to estimate costs, calibrate equipment, assess quality, and monitor inventories.
Science and engineering disciplines depend on the rigor that measurements provide, but what
does measurement really mean?
According to Fenton, “measurement is the process by which numbers or symbols are assigned
to attributes of entities in the real world in such a way as to describe them according to clearly
defined rules”. An entity is a person, place, thing, event or time period. An attribute is a feature
or property of the entity.
To measure, we must first determine the entity.

Example: We could select a car as our entity. Once we select an entity, we must select the
attribute of that entity that we want to describe. For example, the car’s speed or the pressure in
its tires would be two attributes of a car. Finally, we must have a defined and accepted mapping
system. It is meaningless to say that the car’s speed is 65 or its tire pressure is 75 unless we know
that we are talking about miles per hour and pounds per square inch, respectively.

13.4 Product Quality Management

Delivering products with high quality — defined as “meeting specifications at the lowest possible
cost” as well as “delivering the value a customer derives from a product or service” — is a top
priority for manufacturers and industrial operations. Quality has many aspects and Invensys
Operations Management applications have provided integrated quality management
functionality to tens of thousands of companies worldwide.
Invensys quality applications cover the gamut: from real-time process visibility to methods for
data monitoring and alarming; historian data capture and reporting functionality to store and
display voluminous process data for quality analysis; enterprise-wide SPC; integrated MES for
specification management, genealogy, BOM enforcement, OEE and downtime monitoring; batch
recipe management software to collect information on batch quality and recipe specifications;
and underlying ArchestrA framework for monitoring and configuring data levels and application
templates to deliver nearly any quality capability.
