## Content

**Intro:** Order desks are often staffed by habit until backlogs and errors appear. A workload model starts from the minutes each order line and contact consumes, then adds shrinkage, occupancy and a peak factor to give a defensible headcount.

**Sections:**

#### How to use it

**Body:** Enter average daily orders and lines per order, then the minutes spent entering and confirming a line. Add inbound calls and emails with their handle time. Set paid hours, shrinkage and target occupancy, plus a peak day factor for busy periods. The result shows reps required and the headcount rounded up, with annual cost. Use the chart to plan for growth in order volume.

#### The method

**Body:** Daily workload in hours equals order lines times minutes per line plus contacts times minutes per contact, divided by 60. Productive hours per rep equal paid hours times one minus shrinkage times occupancy. Required reps equal workload times the peak factor divided by productive hours. Occupancy below 100 percent leaves room for variation in arrivals, which keeps response times acceptable.

**Bullets:**

- Shrinkage of 15 to 25 percent is common once leave and training are counted
- Occupancy of 80 to 90 percent is a typical planning range
- EDI and portal orders reduce minutes per line sharply

#### Common mistakes

**Body:** Many plans use average day volume and forget that month-end spikes drive the backlog. Others count minutes only for keystrokes and ignore clarifications, credit checks and corrections. Time a sample of orders in your ERP, including exceptions, and use the average. If orders arrive through EDI or a portal, enter only the manual share so you do not staff for work that no longer exists.

**Cta:** Netray can analyze ERP order timestamps and user activity to measure real handling time per order line, giving you a better input than a stopwatch.

**Faq:**

#### What is shrinkage?

**Answer:** The share of paid time when reps are not available to work orders, such as holidays, sickness, breaks, training and meetings. Include all of it to avoid understaffing.

#### Why not plan for 100 percent occupancy?

**Answer:** Work arrives unevenly. A team that is fully occupied on average has long queues and errors at peaks. A planning range of 80 to 90 percent is usual.

#### How do I choose a peak factor?

**Answer:** Divide your busiest weekly or monthly daily average by the overall average. Many order desks see values between 1.1 and 1.4.

#### Does this suit phone queues?

**Answer:** Only roughly. If you manage a strict phone service level, use an Erlang style queue model for the call portion.
