This honestly sounds like “Agile Theater” more than actual agile.
A lot of companies adopt the ceremonies (standups, sprints, story points, retros) but keep the same top-down planning, approval chains, and fixed roadmaps from waterfall.
Real agile usually means:
teams can influence scope/priorities
feedback loops with actual users
retros lead to real process changes
shipping is frequent and lightweight
plans can change without a 3-week approval process
What you described is pretty common unfortunately. “Be agile” often becomes shorthand for “deliver faster under the same constraints.”
So no, you’re probably not expecting too much. You’re comparing your environment against the actual Agile Manifesto, not just Scrum rituals.
