1
00:00:00.000 --> 00:00:04.117
For the fictional review, use a user
requirements specification,

2
00:00:04.237 --> 00:00:07.693
or URS, at revision three, drawing
revision B

3
00:00:07.813 --> 00:00:09.813
and risk record revision two.

4
00:00:09.933 --> 00:00:12.664
These references are teaching
placeholders.

5
00:00:12.784 --> 00:00:17.093
A baseline is the defined set of
information used for the review.

6
00:00:17.213 --> 00:00:21.373
If one reviewer reads revision A while
another reads revision B,

7
00:00:21.493 --> 00:00:24.258
apparent agreement may hide a different
design.

8
00:00:24.378 --> 00:00:26.618
Record the document identifiers,

9
00:00:26.738 --> 00:00:29.319
revisions and approval status together.

10
00:00:29.939 --> 00:00:33.843
Suppose the process team has not defined
the batch-volume range.

11
00:00:33.963 --> 00:00:36.481
The supplier offers a vessel capacity,

12
00:00:36.601 --> 00:00:40.419
but a catalogue capacity is not an agreed
process need.

13
00:00:40.539 --> 00:00:42.907
Raise a question to the process owner

14
00:00:43.027 --> 00:00:47.550
and record the consequence for impeller
location and mixing verification.

15
00:00:47.670 --> 00:00:50.977
The design review may examine unrelated
matters,

16
00:00:51.097 --> 00:00:55.726
but it cannot conclude that mixing is
suitable across an unspecified range.

17
00:00:55.846 --> 00:00:57.958
Unknown inputs should stay visible.

18
00:00:58.578 --> 00:01:01.402
An arrangement drawing shows physical
placement.

19
00:01:01.522 --> 00:01:04.039
A piping and instrumentation diagram

20
00:01:04.159 --> 00:01:06.630
shows process connections and instruments.

21
00:01:06.750 --> 00:01:11.166
A functional specification describes
intended control behaviour.

22
00:01:11.286 --> 00:01:15.318
Our teaching package also includes
material specifications,

23
00:01:15.438 --> 00:01:18.339
a cleaning concept and an interface
register.

24
00:01:18.459 --> 00:01:20.998
These documents answer different
questions.

25
00:01:21.118 --> 00:01:24.019
A drawing label such as temperature
control does

26
00:01:24.139 --> 00:01:26.139
not describe alarm delays,

27
00:01:26.259 --> 00:01:29.480
sensor failure responses or operator
permissions.

28
00:01:29.600 --> 00:01:32.777
Request the document that actually
supports the claim.

29
00:01:33.397 --> 00:01:38.197
During review, the supplier issues
revision C with a different outlet valve.

30
00:01:38.317 --> 00:01:42.199
Do not silently replace the drawing and
keep the old signatures.

31
00:01:42.319 --> 00:01:45.605
Compare the change, identify affected
requirements

32
00:01:45.725 --> 00:01:48.391
and risks, and obtain the appropriate
review.

33
00:01:48.511 --> 00:01:51.114
Record which conclusions remain applicable

34
00:01:51.234 --> 00:01:53.234
and which need reassessment.

35
00:01:53.354 --> 00:01:56.533
The goal is not to restart every check
automatically,

36
00:01:56.653 --> 00:02:01.367
but to prevent an unreviewed design from
inheriting an earlier conclusion.
