The McCall model addresses three areas of software quality: product operation, product revision, and product transition. Product operation focuses on usability, integrity, efficiency, and correctness. Product revision examines testability and maintainability. Product transition considers portability, reusability, and interoperability. The Boehm model defines three levels of quality attributes: primary uses, intermediate constructs, and primitive constructs. Primary uses include as-is utility and maintainability. Intermediate constructs are flexibility, reliability, portability, efficiency, testability, understandability, and usability. Primitive constructs result in measurable properties.
The document introduces Quality Vision, an integrated quality and safety management software solution.

Data Quality Model
Consistency
The absence of apparent contradictions within data
Inconsistency can be verified on the same or different entities
Example: An employee's birth date cannot be later than his
“recruitment date”
Currency
Currency is the extent to which data is up-to-date
It is critical for volatile data (Ex: frequently updated data, as wind
speed or climate temperature)
Example 1: When attending a course, a student needs to know
the right timetable before its starting date
Example 2: A flight seat cannot be available after it has been
assigned to someone; so the flight seat data value must be stored
before another user asks for the same data
28. Software Quality Requirements & Evaluation 30
Completeness
From a computer system's point of view
The extent to which all necessary values have been assigned
and stored in the computer system
Refers both to entity occurrences and to attributes of a single
occurrence
From an end-user perspective
The extent to which data are sufficiently able to satisfy user's
stated needs from quantitative point of view
Includes also the capability of data to represent the context
observed by users
Example: if an entity refers to a company's employees, all the
employees must be recorded with all attributes requested to
satisfy a user's stated needs
Data Quality Model
29. Software Quality Requirements & Evaluation 31
Precision
The capability of the value assigned to an attribute to provide the
degree of information needed in a stated context of use
Example: to represent the duration of a marathon race the
minimum unit of time must be seconds; to represent the duration
of 100 meters race the minimum unit of time must be milliseconds
Accuracy
The degree to which a data value conforms to its actual or
specified value
Data Quality Model
30. Software Quality Requirements & Evaluation 32
Accuracy: Two main aspects
Syntactical accuracy
The closeness of the data values to a set of values defined in a
domain considered syntactically correct
Example: a low degree of syntactical accuracy is when the word Mary
is stored as Mary
Semantic accuracy
Semantic accuracy is defined as the closeness of the data values to
a set of values defined in a domain considered semantically correct
Example: a low degree of semantic accuracy is when the name John
is stored as George. Both names are syntactically accurate, because
of the domain of reference in which they reside, but George is a
different name
Data Quality Model
31. Software Quality Requirements & Evaluation 33
Security
The capability of the data to be accessed and interpreted only by
authorized users
Example: data that refer to personal or confidential information
like health or profit must be accessed only by authorized users or
must be written in secret code
Availability: The capability of data to be always retrievable
Note: a particular case of availability is concurrent access (both
to read or to update data) by more than one user and/or
application
Example: data must be accessible also during managing
operations like backup
Data Quality Model
32. Software Quality Requirements & Evaluation 34
Recoverability
The capability of the data to maintain and preserve a specified
level of operations and its physical and logical integrity, even in
the event of failure
This standard refers to the quality of data, not the system: the
characteristic of recoverability is related to the data that must be
recoverable
Note : Recoverability can be provided by features like commit /
synchpoint, rollback (fault-tolerance capability) or by backup-
recovery mechanisms
Example: when a media device has a failure, data stored in that
device must be recoverable
Data Quality Model
33. Software Quality Requirements & Evaluation 35
Understandability
The extent to which the real meaning of data is easy for users to
comprehend
The extent to which data is in appropriate languages, symbols and
units, and
The degree to which data definitions are clear [5], [10]
Note : some information about data understandability are provided
by metadata
Example : To represent a State (within a country) , the standard
acronym is more understandable than a numeric code
Data Quality Model
34. Software Quality Requirements & Evaluation 36
Manageability
The capability of data to be stored appropriately from a functional
point of view
Example : Data representing costs: stored like numeric and not
like string, to allow users to carry out algebraic operations
Efficiency
The capability of data to be processed (accessed, acquired,
updated, etc) and to provide appropriate levels of performance
using the appropriate amounts and types of resources under
stated conditions
Example : Using more space than necessary to store data can
cause waste of storage, memory and time
Data Quality Model
35. Software Quality Requirements & Evaluation 37
Changeability
The capability of data to be modified in its type, length or assigned
value for changes in technological environment, in requirements
or in functional specifications
Example : changing the “address” attribute in its length must be
allowed if needed
Portability: Also referred to as “Interoperability”
The capability of data to be moved from one platform to another;
this includes the capability of data to be also installed and
replaced in its destination platform. It refers particularly to
homogeneous and coherent set of data
Data Quality Model
36. Software Quality Requirements & Evaluation 38
Productivity
The capability of data to enable users to carry out his task in an
efficient way by using an appropriate amount of resources, and
the extent to which data is applicable and helpful for the task
Data are productive for users when they satisfy the scope and the
goal of his information needs
Safety
The extent to which data is related to their capability to achieve an
acceptable level of risk to people, businesses, properties or the
environment in a specified context of use
Example : data concerning blood group are relevant to users of
health care computer systems
Data Quality Model
37. Software Quality Requirements & Evaluation 39
Credibility
The extent to which data are regarded as true and credible by
users
Accessibility
The capability of data to be accessed, particularly by people who
need supporting technology or special configuration because of
some disability.
Example : data that must be managed by a screen reader cannot
be stored as an image.
Regulatory compliance
The capability of data to adhere to standards, conventions or
regulations in force and similar rules relating to data quality.
