  10. Project Plan Updates and Reporting“Tricks of the Trade” • For neat single page print-outs of large plans, cut and paste from Excel to PowerPoint and resize the pasted object to fit on a page. (Paste as Picture Enhanced Metafile or as Device Independent Bitmap); • Use every second row for the plan, then use the other row to plot progress (shade in a different colour or using a different pattern); • Changes to plan, growth in scope etc. can be accommodated by inserting rows and columns; • Always keep a separate copy of the original plan for reference.
