1̲ ̲ ̲I̲N̲T̲R̲O̲D̲U̲C̲T̲I̲O̲N̲
This Engineering Change Proposal covers the technical
and financial impacts for a proposed standardization
of memory module size. Two options are considered.
The first option is upgrading all PUs to 2 times 128K
words. The second option is to upgrade all large sites
to 2 times 128K words, and downgrade the small sites
to 1 time 128K words per PU.
2̲ ̲ ̲P̲R̲I̲C̲E̲ ̲Q̲U̲O̲T̲A̲T̲I̲O̲N̲
This cost for both option considers cost for new 128K
modules and savings from 32K and 64K modules, which
are no longer required. The benefit on spare savings
is also considered.

Some of the immediate benefits which appears by introduction
of standardized memory board is that the RSPL can be
reduced as follows:
32K qty. 13 unit price: Dkr. 36,427 = DKr.
473,551
64K qty. 10 unit price: DKr. 47,139 = D̲K̲r̲.̲

C̲o̲s̲t̲ ̲i̲m̲p̲a̲c̲t̲ ̲o̲n̲ ̲s̲p̲a̲r̲e̲ ̲p̲a̲r̲t̲s̲
By introduction of standardized memory board the RSPL
can be reduced as follows:
32K qty. 13 unit price: Dkr. 36,427 = Dkr.
473,551
64K qty. 10 unit price: Dkr. 47,139 = D̲k̲r̲.̲
̲
̲4̲7̲1̲,̲3̲9̲0̲
Total value of removed spares Dkr.
944,941
The net benefit of upgrading some sites and degrading
other sites plus considering spare part savings is
Dkr. 1,291,451 for the hardware only.
However if this option is exercised, there is serious
project impacts, since the CAMPS at the sites cannot
provide the full range of required facilities with
only 128K per PU.
If SHAPE wishes to pursue the option of operating sites
with only 128K per PU, then this will have cost and
schedule impacts on software development. (See section
3 and 5) since now two versions of software have to
be developed; one for the large site, and one for the
small site.
Any cost for software development in option 2 might
easily exceed the stated hardware benefit.
3̲ ̲ ̲S̲C̲H̲E̲D̲U̲L̲E̲ ̲I̲M̲P̲A̲C̲T̲
There will be no schedule impact if SHAPE accepts option
1 within the bidding provision.
Regarding option 2, there will be a schedule impact,
but it is not possible to estimate the amount prior
to a common understanding between SHAPE and CR, of
which requirement can be removed from the small sites,
and the corresponding software modification needed.

4.1 V̲A̲L̲I̲D̲I̲T̲Y̲
The cost and schedule implications stated in section
2 and 3 above for option 1 are under the assumption,
that the go ahead is given before 1982-01-08.
The option 2 terms must await further clarification.
See section 5.
4.2 D̲E̲L̲I̲V̲E̲R̲Y̲
The new memory modules will be delivered as part of
the CAMPS main sites.
4.3 A̲C̲C̲E̲P̲T̲A̲N̲C̲E̲ ̲C̲R̲I̲T̲E̲R̲I̲A̲S̲
The change has no impact on the present acceptance
baseline.
4.4 T̲Y̲P̲E̲ ̲O̲F̲ ̲P̲R̲O̲P̲O̲S̲A̲L̲
This is a firm fixed price proposal.
4.5 P̲A̲Y̲M̲E̲N̲T̲ ̲P̲L̲A̲N̲
30% of the total at approval of the ECP.
60% at factory acceptance.
10% at site acceptance.

Both option will standardize the memory boards to be
used. so that only 128K word RAM will be used for PU
memory. Option 1 will also standardize the actual memory
size in all PUs. However, option 2 which will degrade
the small sites, does entail non standardization consequences
in some vital aspect.
Regarding option 2 it is not possible to degrade the
memory size of the small sites without removing some
of the programs and hence CAMPS functions in the small
sites.
Irrespectively of which programs and capabilities could
be removed from the small sites, any change which will
make the software at the sites different, is not a
recommendable change. In addition to the actual removal
of some programs, the system generation, the functional
testing and the documentation must be changed to reflect
the software configuration operating in a downgraded
memory size.
The software maintenance task is also made more difficult.
6̲ ̲ ̲R̲E̲C̲O̲M̲M̲E̲N̲D̲A̲T̲I̲O̲N̲
CR strongly recommend option 1, which will result in
a complete standardization of memory boards and size.
Regarding option 2, CR cannot recommend this change
under the present understanding of SHAPE intention
with the CAMPS project, see section 5.
