As complex projects generate a large amount of documents, these documents are going to have to get sign off and approval from stakeholders. Everything needs attention and must be signed for, which is in fact the legal proof that these documents have concluded. That includes closing all contracts you might have made with internal team members, specialist sub contract teams or any other resources you contracted with.
At this point this includes addressing all outstanding payments. You want to make sure that all invoices, commissions, fees, bonus payments, etc. are paid. Complete all the costs involved with the project. It’s not complete, if it’s not paid for.
This includes reports such as timesheet reports, so you can quickly see the hours worked by a team member over the life of the project. You can also create more stakeholder specific reports, like status reports, variance reports or project plan reports.
Documents such as project review meeting records, SWOT analyses and PESTEL analyses would be required for the final stages. Collate all records and get ready to be stored or archived.
