171101 - Follow up
171102 -
171103 - This record pulls together examples of complex scenarios that
171104 - illustrate how mistakes occur and how they can be off-setting for
171105 - awhile, but eventually become manifest, so that Murphy's Law is
171106 - explained.
171107 -
171108 - Example of configuring computer network using Internet is at ref SDS 1
171109 - 1680,
171110 -
171111 - Another example at ref SDS 2 3389,
171112 -
171113 - Cost of mistakes is at ref SDS 3 5182.
171114 -
171115 - An example of compound mistakes masking a serious error in computer
171116 - coding is at ref SDS 4 2386.
171117 - ..
171118 - One reason people drift off course is that every mistake does
171119 - not have an immediate impact, as explained in POIMS.
171120 -
171121 - Delayed impact can be cause by multipel errors that balance each
171122 - other, until a subsequent event that corrects one mistake, then the
171123 - other becomes manifest and seems to produce results that conflict with
171124 - experience that has accumulated under the prior mistaken conditions.
