For a Sprint, progress is monitored in a burn-up chart with bars. What makes the bar become longer?

Question

Options

• AThe progression of time.
• BWork is added to the Sprint Backlog.
• CWork is deleted from the Sprint Backlog.

• A
  3% (1)
• B
  3% (1)
• C
  94% (30)

Explanation

In a burn-up chart with horizontal progress bars, the bar represents completed work as a proportion of total Sprint Backlog scope. When uncompleted work is deleted from the Sprint Backlog (C), the total scope shrinks while already-completed work stays the same - meaning the same completed points now fill a larger fraction of the total, so the bar visually extends further toward 100%.

Why A is wrong: Time passing alone neither completes work nor removes scope; the bar doesn't move simply because another day elapsed.

Why B is wrong: Adding work to the Sprint Backlog increases the total scope denominator, which means completed work now represents a smaller proportion - the bar actually gets shorter or shrinks relative to the new total.

Memory tip: Think of the bar as a "how full is the bucket?" gauge. Deleting unfinished items is like shrinking the bucket - the same amount of water (completed work) suddenly fills it more, so the bar grows longer. Adding work is like using a bigger bucket - the same water fills less of it.
