Advice on how to organize a large scale project across business areas. Portfolio vs Program, subcategory option in portfolios?
I am looking for the best way to organize a large scale initiative across business areas, but grouped by quarter. A little background, we are a large company- but only 2 business areas utilize WF. Currently the other business area and us(which we are the media department) use portfolios to keep our projects separate. As the media department, we receive requests from several different business areas for projects(photography/videography/live events, etc). We are about to undertake a large project where all our business areas will be requesting we take photos for them, but its all under one initiative umbrella if you will. I need a way to organize it for visibility and keep it separate from our normal workflow projects. Trying to understand the difference between program vs portfolio. I know a program cannot exist without a portfolio. I am leaning towards creating another portfolio naming it with this initiative and then putting all the project requests under it- my question maybe is more of how can I organize these projects within the portfolio? I need them organized by Quarter. Thanks for any input!
