A task list describes work, a map describes authority
Task lists answer the question of what will be done. They say nothing about who may change it, who pays for it, or what happens when two parties want different things in the same space. In a single-occupier building those questions never arise. In a building with an owners corporation, a building manager, several tenancies and a landlord, they arise constantly and a task list is silent on all of them.
The map is a short document and it answers them permanently. Each space gets three attributes: whose property it is, who decides what happens in it, and which budget funds it. Once that exists, the task detail almost writes itself, and every subsequent question about a request, a variation or a dispute can be resolved by looking at one page rather than by negotiating. Most disputes in a multi-occupier building are authority questions wearing a service complaint as a disguise.
