Prioritisation of incoming work in a team can be a challenge, but there are many frameworks around which help with that. Sooner or later teams find their way of prioritising jobs and learn how to balance business, technical and customer needs. Can this scale to a team of teams? In this talk, Anna will share the lessons she learned working with multiple stakeholders in a large organisation spread across different countries, where every piece of work is worth millions of pounds and has a great operational or customer impact. You will get insights on how to introduce and scale a prioritisation method, respecting unknown unknowns, complex tech environment and time pressure.
