Hi @Alena_K , I feel your dilemma. When it comes to ‘mega-projects’, deciding on whether it should be in one single project or broken into various ‘bucket’ projects usually has to do with the following factors, which some you have already covered.
Custom fields and purpose: what is the purpose of each ‘bucket’ project? would each one require (completely) different custom fields? would they benefit from having their own particular ‘Status’ field, for example? Are they perhaps completely different in nature? For example, is one bucket used for form intakes, another is used as a CRM to capture all contacts working on the project and another for a particular deliverables list?
Amount of tasks: will the ‘bucket’ projects have a substantial amount of tasks? Anything less than about 15-20 tasks may not benefit being an actual Asana project, instead perhaps a Section within a project or even 15-20 subtasks within a task…?
Status updates: is it beneficial to post status updates for each of the ‘bucket’ projects? Even so, if you want one status update to rule them all, that could be a status update of the portfolio that would contain all the ‘bucket’ projects, or you could designate the main ‘bucket’ project as the one that will have Status updates posted, on behalf of the entire project.
Gantt / timeline: would it be beneficial to have a view of all tasks of the project in one Gantt view? You could still breakup your project into buckets and multi-home all tasks into one ‘master’ project list (using Rules, as you mention). Alternatively, you could combine multiple projects into one Gantt view using instagantt.com
Privacy/access: would it be beneficial to hide certain aspects of the project from other stakeholders? For example, do you have any sensitive tasks with financials or non-client facing data that would be best to be kept in a separate, private project, accessible to a few select members? Sharing one master project with everyone could be great for visibility, but perhaps not for Guests or the external partners that you mention.
In conclusion, I believe if the answer is ‘yes’ to perhaps ANY of the above factors, I would support your reasoning for going down the route of breaking the project into numerous ‘buckets’ or initiatives.
I encourage others to weigh in, in case I’ve missed any other factors.
