Erlang C sizes each interval, then shrinkage turns seats into scheduled people; both steps appear, assumptions alongside, in an MSHR 6610 Week 4 staffing model for a utility contact center.

What a finished MSHR 6610 Week 4 staffing model looks like
A spreadsheet-style table and four pages of explanation. Rows are half-hour intervals from the previous week's analysis; columns carry calls expected, average handle time, the service target, and the agents Erlang C says are needed to meet it, all labeled illustrative. The queuing model is named plainly and described for its central logic: given how fast calls arrive and how long each takes, it estimates the chance a caller waits and for how long. A second block applies shrinkage, the share of paid time lost to breaks, training, meetings and absence, to turn agents needed on the phones into agents who must be scheduled. An assumptions column sits beside every figure. The last page tests two assumptions, handle time and shrinkage, and shows how far the requirement moves when each is wrong.
How a MSHR 6610 Week 4 example is structured
Inputs are listed before any calculation, each with its source or its illustrative label, because every later figure inherits their errors. The Erlang C step is worked through completely for a single interval, so a reader can follow it, and then applied across the table. Shrinkage stays a separate step rather than disappearing into handle time, which lets a manager see how much of the requirement comes from time off the phones rather than time on them. The schedule requirement follows, expressed as heads per interval rather than full-time equivalents. Sensitivity comes next and is brief: two inputs moved up and down, with the change in agents reported. The limits paragraph closes the model, noting that Erlang C assumes callers never hang up and therefore tends to overstate the staff needed.
Inputs, each with a label
Calls per interval, handle time, service target and shrinkage are listed first, with source or illustrative tag. A reader who doubts the total can find the input responsible.
One interval worked by hand
The Monday ten o'clock half hour is carried through Erlang C step by step. After that, the table applies the same logic to every other interval without repeating the explanation.
Shrinkage as its own line
Breaks, coaching, training and absence are totaled as a share of paid hours. Applying that share separately shows how many scheduled people it takes to keep the required agents on the phones.
Two inputs moved
Handle time and shrinkage each shift up and down by a stated amount. The change in required agents is reported for both, showing which assumption the model is most exposed to.
What Erlang C assumes
Callers in the model wait forever and never abandon. Real callers hang up, so the model tends to recommend more staff than the floor strictly needs, and the paper states the direction of that error.
Where marks go in MSHR 6610 Week 4
Assumptions carry the weight here, and a model producing a clean headcount with its inputs buried in a footnote asks the reader to trust a number the course wants them able to rebuild. The worked interval earns a distinct share, since it proves the author understands what the queuing model does rather than pasting an online calculator's output. Keeping shrinkage separate is credited heavily, because that single step often explains why a floor feels short while the payroll looks full. The sensitivity test separates stronger models: showing, for instance, that a modest rise in handle time adds more required agents than one planned hire would cover is the kind of finding operations leaders act on. Naming the model's limits scores as judgment. Rounding agents down anywhere costs points; fractional agents round up.

MSHR 6610 Week 4 questions, answered
Do I need to calculate Erlang C by hand?
No. Most people use a spreadsheet function or a free calculator, and the sample says which it used. What the rubric usually wants is evidence that you understand the inputs and the output: arrival rate, handle time, target, and the probability of waiting that results. Working one interval in the text, with the calculator doing the rest, shows that understanding without turning the paper into arithmetic.
What counts as shrinkage?
Any paid time an agent is not available to take calls. Breaks, lunches, coaching sessions, training, team meetings, sick days and vacation all belong, and some operations add system downtime. The sample totals these as a share of paid hours and labels the figure illustrative. If your case gives a shrinkage rate, use it; if not, list the components you assumed so a reader can challenge any one.
Should the model use Erlang A instead?
It can, if your course covers it. Erlang A adds callers who abandon, which usually brings the requirement down and closer to what a real floor needs. The sample keeps Erlang C because the prompt names it and says plainly that the result is likely an overstatement. Either model earns credit when its assumptions are stated and its direction of error acknowledged.
