Once upon time, when I was an investment banker I often found myself in a group of 14 around some conference table.
The routine was amazingly similar for such gatherings - somebody distributed annual reports, accounts or financial spreadsheets. That's when you could see 14 HP 12cs (financial calculators) being whipped out simultaneously. Pencil at ready, 14 souls threw themselves at the task of extracting real data from the manipulated numbers, then adding their own logic.
Soon you would hear 14 sets of arguments why their logic was right and how it played into their interests - lower price, higher price. And the day passed with bad coffee and messy sandwiches.
And history, history comes to us via someone. To understand the reality we compare documents, stories and images and try our best to read between the lines. Just like investment bankers, trying to find a nugget, or at least something useful.
Extracting reality from subjective writing. Shaving off iffy logic from manipulated data.
Why do we always use, save, produce and present manipulated data, why don't we stick to raw data and apply logic to the data only when needed?
Because "forms, documents, books, stories, poems and songs" was the only solution when we only had pen and paper and not even that to capture events for the future.
The persons that events happens to usually perish over time. Become history. Thus event documentation.
Then software came and copied that method (how silly!), so now we have:
Event and transaction driven BPxx and ERP process systems that produces subjective event documentation; forms and documents. Funny thing, the objects the events and transactions happens to does not perish in a system, still only events are documented. Hmmm.
Word-processors, accounting, etc. - applications that save manipulated data, subjective results.
But we gained one thing with IT: We're now able to produce more documents at a faster pace. Great, now we have to shave off the logic of 26 different numbers instead of three numbers. Now we have 34 event reports to represent the thing it happened to. Plus the thing itself of course. A folder of 35 documents to represent one thing. Hmmm.
Hello reconciliation, hello errors, hello confusion.
Sisyphus would have felt at home. Nah, he would have been confused when he could not find the boulder he was supposed to push, only a stack of reports from each time it rolled back down the mountain.
