Reverse engineering calculate jobs

I want to standardise a small set ...is a weekly operations sheet that mirrors the cadence of my business: columns for each day, space to log key tasks, quick-reference status indicators, and a summary row that totals completed versus pending items. Finally, I need a roster sheet for staff scheduling. It should sit alongside the operations sheet, pull the same dates, allow easy drag-and-drop (or drop-down) shift assignments, and calculate total hours per employee. Please link the three sheets where helpful so I only type shared information once, build in simple formulas for totals and alerts, and keep everything ready for Google Sheets or Excel—whichever you prefer—as long as it’s editable later. I’m after something clear, functional, and easy for my team t...

The task is to convert a set of engineering drawings supplied only as PDFs from Arabic into English while maintaining absolute technical accuracy. All dimensions, call-outs, equations, symbols, notes, captions, footnotes and page numbers must stay exactly where the original designer placed them, so the translated file can be over-laid onto the source without any visual drift. Because these drawings will be referenced against ISO, ASTM and IEC requirements, terminology must follow the same standards. Whenever an expression is ambiguous, add a brief in-text comment so reviewers can see the issue immediately. I will provide a brief sample page for you to test your approach; once approved, the full batch follows. Preferred profile • Engineering degree or equivalent e...
