  Decision making and requirements scoping occupy central roles in helping to
develop products that are demanded by the customers and ensuring company
strategies are accurately realized in product scope. Many companies experience
continuous and frequent scope changes and fluctuations but struggle to measure
the phenomena and correlate the measurement to the quality of the requirements
process. We present the results from an exploratory interview study among 22
participants working with requirements management processes at a large company
that develops embedded systems for a global market. Our respondents shared
their opinions about the current set of requirements management process metrics
as well as what additional metrics they envisioned as useful. We present a set
of metrics that describe the quality of the requirements scoping process. The
findings provide practical insights that can be used as input when introducing
new measurement programs for requirements management and decision making.
