MTRs are verified by:…86…1 …02… …02… …02… …02…
1) Testing/analysis in accordance with sections
4.6.1.1, 4.6.1.2 and 4.6.1.3 or,
2) Provision of acceptable evidence of conformity
to requirements, i.e. evidence supported byprior
observation of system or module performance
over a length of time sufficient to have the
same degree of confidence as the test procedure
that the required availability can be archived.
3) Provision of evidence that the unit or module
is pat of the CAMPS R and M programme.
b) The set of units and modules, taken together, shall
make up the equipment of the R&M model(s) used

a) Tests shall be performed to measure the MTBF of
all units and modules having a predited MTBF value
of 3500 hours or less. The contractor need not
test all the individual units of a module being
tested unless the unit has a MTBF value less than
3500 hours and is part of another module which
is not being tested.
b) R&M testing shall be conducted in accordance with
an approved unit or module test plan. The overall
system test programme shall be planned so that
reliability data is obtained rom as many functional
tests as possible. In this manner the performance
of reliability testing, per se, will be reduced
to the minimum necessary for the demonstration
of system compliance with the R&M availability
requirements.
c) The R&M test pogramme shall make provisions for
the accumulation of sufficient testing time on
each type of module. The accumulated testing time
shall be equivalent to at least three multiples
of either:
1) the predicted MTBF value of the module with
an MTBF f 3500 hours or less, or
2) the largest predicted unit MTBF value for units
having a predicted MTBF value less than 3500
hours and forming part of a module with a MTBF
value greater than 3500 hours.
d) The R&M test programme shall provide for emonstrating
that unit and module MTBF values are equal to or
greater than the respective predicted values, to
a lower confidence limit value in accordance with
the following schedule:
80% lower confidence limit value at the time of
Final Accepance.
e) The lower confidence limit values of MTBF shall

a) The contractor shall justify the use of MTBF values
greater than 3500 hours for individual units and
for modules, without redundant units, by means
of analytical calculations. Such calculations shalluse
values taken from actual test data on "like" or
similar equipment or from a component analysis,
utilizing values taken from recognized sources,
e.g. reliability and maintainability handbooks
maintained by National Government and by Industry.
) The Project Implementation Plan shall identify
those units and modules which have predicted MTBF
values greater than 3500 hours, and which will
have the MTBF values justified rather than tested.
The list shall include the predicted value of MTBF
or such units and modules. The list may be changed
as the programme progresses provided notification
is given at least 60 days in advance of starting
or cancelling any planned tests. The change process
contemplated for this list is the same as thatprovided
in the contract for all items (data) under Configuration

a) Tests shall be performed to measure the MTTR of
all types of units and modules with a predicted
MTTR valueof 45 minutes or less.
The contractor need not test individual units of
a module that is being tested unless the unit is
also a part of another module that is not being
tested.
b) The MTTR measurements shall include corrective
and preventive mintenance actions, the time to
localise the failure to a particular module, time
to replace the failed module, verify the repair
action and restoring the system to operational
configuration exclusive of any software load requirements.
The MTTR doesnot include the repair time of the
failed module. The R&M test programme shall provide
for demonstrating that unit and module MTTR values
are less than or equal to the respective predicted
MTTR values to an upper confidence limit value
in accordanc with the following schedule:
1.80 % upper confidence limit value at the time
of Final Acceptance
c) The upper confidence limit values of MTTR shall

those units and modules that have MTTR values greater
tan 45 minutes, together with the predicted MTTR
values. Reasons for assigning a MTTR value in excess
of 45 minutes to a unit or module shall be given
and shall explain the maintenance procedures involved
in restoring such a unit or module to servic when
a malfunction occurs.
b) The list of units and modules having MTTR values
greater than 45 minutes may be changed as the programme
progresses provided notification is given at least
60 days in advance of starting any testing or cancelling
an planned tests. The change process contemplated
for this list is the same as that provided in the

5.1 S̲y̲s̲t̲e̲m̲s̲ ̲P̲r̲i̲n̲c̲i̲p̲l̲e̲s̲
Fundamental properties of the software are its quality,
integrity and flexibility. The software shall meet
the oprational requirements together with the requirements
for ease of maintenance and modification. The software
shall be structured in a clearly identifiable hierarchical
way to ensure that the integrity and reliability requirements
of this specificatin are met. At the same time it shall
be readily expandable and must provide the facilities
specified below in such a way that the tasks of future
modification, error elimination and maintenance are
facilitated.
a) The software shall be provided a a complete, well
structured system consisting of three s̲u̲b̲-̲s̲y̲s̲t̲e̲m̲s̲:̲
1) The system software comprises all the software
(i.e. the program code, permanent data, pre-set
work space etc.) which is required to be resident
in or accessible to the system during its operation.
The system software shall provide the services
to the applications software.
2) The support software comprises all off-line
software required to supportthe testing and
maintenance of the operational system.
3) The applications software is defined as the
software providing the functional capabilities
called for in this specification.
b) The software, in conjunction with the hardware,
shall be designed to detect and limit the effect
of hardware faults which occur in the system. Upon
detection of the fault, actin should be taken to:
1) Report the fault.
2) Optimize the remaining system operational capabilities
while the fault persists.
c) The system design shall seek to maintain maximum
isolation and independence between units of all
types during rogram design and implementation and
during on-line operation of the system.
d) In the construction of program code, clarity of
meaning shall be a major consideration. When writing
the program code comments shall be inserted to
aid comprehension nd improve the readability.
e) It is mandatory that no instruction and constants
of the system software are modified during execution.
If it is done the circumstances must be well documented
and the program listing must contain complete cross-refrencing
comments. In the applications software the use
of this technique shall be unacceptable.
f) The data areas of a module shall be logically contiguous
and all exchange of data between different modules
shall take place either through well deined shared
data areas or by a parameter passing.
g) The software shall be carefully documented in parallel
to the design during the production phase. The
documentation shall form part of the deliverable
software package and conform to the softwae documentation
standards specified elsewhere in this document.

a) The system software facilities must allow the applications
software to be structured in terms of functional
modules.
b) The system software shall include the following
general facilities in some form:
1) Multi-programming and scheduling at run time,
i.e. the provision of a set of processes orequivalent
entities as the basic entities to which processor
time, store and other system resources are
allocated at run time.
2) Store management, i.e. facilites for permanently
or dynamically allocating areas of core store
to processes or thei equivalents for initializing
data areas securely when required; and for
obtaining permanent or dynamic access to such
areas when required.
3) Device control and interrupt response, i.e.
standardized interfaces between hardware devices
(includin traffic channels) and applications
software, such that the system software is
wholly responsible for the immediate control
of hardware device interfaces.
4) Inter-process interfaces, i.e. facilities for
passing activations and data between procsses
over standardized interfaces.
5) Fault handling, i.e. facilities for the detection,
location and containment of software and hardware
faults.
5.3 A̲p̲p̲l̲i̲c̲a̲t̲i̲o̲n̲ ̲S̲o̲f̲t̲w̲a̲r̲e̲
The application software shall be provided as well-structured
module. The application software is to provide, in
conjunction with the system software, all the functional
capabilities called for in this specification. The
application software for each installation shall be
identical or, as a minimum, generated from common
library of program routines.
a) O̲v̲e̲r̲a̲l̲l̲ ̲S̲t̲r̲u̲c̲t̲u̲r̲e̲. The applications code and data
shall be structured in a hierarchical manner into
a well defined set of functional modules and units
at different functional lvels and with distinct
data areas for each transaction processed by the
system.
The ways in which the various applications software
modules are multi-programmed at run-time (i.e.
recursive/re-entry or "fresh copy", etc.) shall
be clearly defined
Communication between modules shall wherever practicable,
take place via standardised system facilities such
as interprocess calls and procedure calls. The
sharing of data areas between two or more units
or modules handling different transactios shall
be avoided and the situations in which such sharing
takes place shall be clearly defined. It shall
be a design aim to ensure that whenever data is
transmitted across an inter-module interface, the
data is in a compact, well defined form.
The process of integrating a module into the system
shall not require recompilation of the other elements
of the system.
b) M̲o̲d̲u̲l̲e̲s̲ ̲o̲f̲ ̲A̲p̲p̲l̲i̲c̲a̲t̲i̲o̲n̲ ̲S̲o̲f̲t̲w̲a̲r̲e̲. It shall be a
design aim that each functional module of applications
software should satify the following criteria:
1) Provide a well defined function or group of
functions at some hierarchical level in the
software system, i.e. can be implemented as
self-contained programming task given a functional
specification, interface specifiations of any
external modules and data structures to which
it must refer.
2) Has well defined, compact input and output
interfaces.
3) Can be separately compiled/assembled.
4) Hides its decisions from other modules (e.g.
it allows access to internal data structures
only through one access mechanism provided
by the module).

a) U̲s̲e̲ ̲o̲f̲ ̲L̲a̲n̲g̲u̲a̲g̲e̲s̲
The software will be implemented in swell.
b) P̲r̲o̲g̲r̲a̲m̲s̲
It is mandatory that programme instructions shall
not be modified during run time and that within
each applications software module the programme
code and constnts should be segregated from the
modifiable data. The direct use of or access to
absolute store addresses by applications programmes
should be reduced to a minimum. Synchronization
processes shall take place at clearly defined points
in the programe. To maintain security and accountability,
reservation and release of shared resources, such
as data areas, must only take place at clearly
defined points in the applications programme.
c) M̲o̲d̲u̲l̲e̲ ̲S̲i̲z̲e̲ ̲C̲o̲n̲s̲t̲r̲a̲i̲n̲t̲s̲
The function of each module hould be readily understandable.
As a rule, no module shall contain more than 250
source statements unless approved by CR QA internally
and notification to SHAPE. It shall be a design
aim to limit the number of modules, exceeding the
250 line limitto 5% of the modules. Each module
must implement a function or function(s) as specified
in this document. Any requirement which would lead
to implementation of a module unable to satisfy
this constraint must be sub-divided into more manageable
unit. It is essential that any constraints imposed
on the module size by compilers, loading methods,
store management arrangements, etc., must be clearly
defined and adequate methods for dealing with these
constraints must be defined and implemented.
5.5 S̲o̲f̲t̲w̲a̲r̲e̲ ̲M̲a̲i̲n̲t̲e̲n̲a̲n̲c̲e̲ ̲a̲n̲d̲ ̲M̲o̲d̲i̲f̲i̲c̲a̲t̲i̲o̲n̲
