I am creating a technical specification with Word 2016 and want to automize formatting of requirements that I will describe. Throughout the document I will have different chapters and sections where I will put my requirements, but want to maintain the requirements formatting fixed throughout the document. Each requirement will consist of a requirement ID and requirement text. I want the requirement ID to autoincrement as soon as I insert a new requirement to the document, i.e.: IRD_001 requirement text IRD_002 requirement text IRD_003 requirement text
Requirement ID needs to be unique and always start with 'IRD_'. Requirements will be scattered throughout the document. It can happen that with version 2.0 of the document I will need to add or remove some requirements. The existing list of requirements shall not be modified though, i.e.
IRD_001 requirement text IRD_004 added requirement text IRD_002 requirement text IRD_003 requirement text
How can I achieve this with MS Word?
