The document discusses specifications, which are explicit sets of requirements for materials, products, or services. It describes different types of specifications like formal, program, functional, and document specifications. It also outlines how specifications are developed by various organizations, their common uses in engineering and business, guidance for writing good specifications, and considerations for process capabilities during production.

of the bolded
words.

4. What is Specification?
• Specification (often abbreviated as spec) is an
explicit set of requirements to be satisfied by
a material, product, or service.
• a type of technical standard.
• Should a material, product or service fail to
meet one or more of the applicable
specifications.

5. how Specification may be develop?
• A technical specification may be developed by
any of various kinds of organizations, both public
and private.
 . Example organization types include a
corporation, a consortium (a small group of
corporations), a trade association (an industry-wide
group of corporations), a national
government (including its military, regulatory
agencies, and national laboratories and
institutes), a professional association (society), or
a purpose-made standards organization such as
ISO.

6. Kinds of Specification
Formal specification
Program specification
Functional specification
Web service specification
Document specification

7. Formal specification
• is a mathematical description of software or hardware
that may be used to develop an implementation
• It describes what the system should do, not
(necessarily) how the system should do it
• it is possible to use formal verification techniques to
demonstrate that a candidate system design is correct
with respect to the specification
• This has the advantage that incorrect candidate system
designs can be revised before a major investment has
been made in actually implementing the design

8. Program specification
• the definition of what a computer program is expected
to do
• It can be informal, in which case it can be considered as
a user manual from a developer point of view, or
formal, in which case it has a definite meaning defined
in mathematical or programmatic terms
• In practice, many successful specifications are written
to understand and fine-tune applications that were
already well-developed, although safety-critical
software systems are often carefully specified prior to
application development
• Specifications are most important for external
interfaces that must remain stable.

9. Functional specification
• In software development, a functional
specification (also, functional spec or specs or
functional specifications document (FSD)) is the
set of documentation that describes the behavior
of a computer program or larger software system
• The documentation typically describes various
inputs that can be provided to the software
system and how the system responds to those
inputs.

10. Web service specification
• Web services specifications
are often under the
umbrella of a quality
management system

11. Document specification
• These types of documents define how a
specific document should be written, which
may include, but is not limited to, the systems
of a document naming, version, layout,
referencing, structuring, appearance,
language, copyright, hierarchy or format, etc
• Very often, this kind of specifications is
complemented by a designated template.

12. • It is common for one organization to refer to
(reference, call out, cite) the standards of
another.
• . Voluntary standards may become mandatory
if adopted by a government or business
contract.
Sometimes the term specification is used in
connection with a data sheet (or spec sheet).
•describes the technical characteristics of an item or
product.
•It can be published by a manufacturer to help people
choose products or to help use the products
•is not a technical specification as described in this article.

13. Uses of Specification
• In engineering, manufacturing, and business,
it is vital for suppliers, purchasers, and users
of materials, products, or services to
understand and agree upon all requirements.
• It is a type of a standard which is often
referenced by a contract or procurement
document. It provides the necessary details
about the specific requirements.

14. • Specifications may be written by government agencies,
standards organizations (ASTM, ISO, CEN, DoD, etc.),
trade associations, corporations, and others.
• A product specification does not necessarily prove a
product to be correct. An item might be verified to
comply with a specification or stamped with a
specification number: This does not, by itself, indicate
that the item is fit for any particular use. The people
who use the item (engineers, trade unions, etc.) or
specify the item (building codes, government, industry,
etc.) have the responsibility to consider the choice of
available specifications, specify the correct one,
enforce compliance, and use the item correctly.
Validation of suitability is necessary

15. Guidance
a standing operating procedure is available to
help write and format a good specification
Specification may include the following:
•Person, office, or agency responsible
for questions on the specification,
updates, and deviations.
•The significance, scope or importance
of the specification and its intended
use.
•Terminology, definitions and
abbreviations to clarify the meanings of
the specification[9][10]
•Test methods for measuring all
specified characteristics
•Descriptive title, number,
identifier, etc. of the
specification
•Date of last effective revision
and revision designation
•A logo or trademark to indicate
the document copyright,
ownership and origin[8]
•Table of Contents (TOC), if the
document is long

16. • Material requirements: physical,
mechanical, electrical, chemical,
etc. Targets and tolerances.
• Acceptance testing, including
Performance testing requirements.
Targets and tolerances.
• Drawings, photographs, or
technical illustrations
• Workmanship
• Certifications required.
• Safety considerations and
requirements
• Environmental considerations and
requirements
• Quality control requirements,
acceptance sampling, inspections,
acceptance criteria
• Provisions for rejection, reinspection,
rehearing, corrective measures
• References and citations for which
any instructions in the content
maybe required to fulfill the
traceability and clarity of the
document
• Signatures of approval, if necessary
• Change record to summarize the
chronological development, revision
and completion if the document is to
be circulated internally
• Annexes and Appendices that are
expand details, add clarification, or
offer options
• Person, office, or agency responsible
for enforcement of the specification.
• Completion and delivery.

17. Process capability considerations
• A good engineering specification, by itself, does
not necessarily imply that all products sold to that
specification actually meet the listed targets and
tolerances. Actual production of any material,
product, or service involves inherent variation of
output. With a normal distribution, the tails of
production may extend well beyond plus and
minus three standard deviations from the process
average.

18. • The process capability of materials and products
needs to be compatible with the specified
engineering tolerances. Process controls must be in
place and an effective Quality management system,
such as Total Quality Management, needs to keep
actual production within the desired tolerances.
• Effective enforcement of a specification is
necessary for it to be useful.
