Workforce management (WFM)
Workforce management (WFM) is the practice of forecasting contact volume and planning staff, shifts and breaks so that the right number of people is available at the right time.
What it is
WFM is the planning discipline of a contact center or any team that answers clients at scale. It connects three things: how many contacts will come, how long each takes, and how fast they must be answered. From that it derives how many people are needed in every interval of the day.
How it works
The cycle has four steps. Forecast: estimate volume by half-hour, using history, seasonality and planned events such as mailings or promotions. Calculate: turn volume into required staff using average handle time and the service level target. Schedule: build shifts and breaks that cover the requirement. Track: compare the plan with reality during the day and adjust.
An illustrative calculation: 120 contacts per hour, 5 minutes each, gives 600 minutes of work per hour, which is 10 people fully busy. Since nobody can be busy 100% of the time and some will be on breaks, the real requirement is noticeably higher.
Why it matters
Staff is usually the largest cost of a service or sales line. WFM decides whether that money is spent where clients actually are. It also protects people: a realistic plan prevents both chronic overload and long idle hours.
The typical mistake
Planning by averages. A daily average hides the peaks where clients wait and the troughs where people sit idle. Another mistake is forgetting shrinkage, the share of paid time when people are not on the line, and forgetting that a mass mailing creates a wave of replies that must be staffed. Forecast in short intervals, include every planned event, and check forecast accuracy weekly so the model improves.

- Collection agency and call center in messaging apps: the economics of switching from calls to chatMoving collections from calls to messaging apps pays off only if you measure it on your own data: compare the connect rate with the reply rate, promises with how many are kept, and the cost per contact before and after. People answer messages more readily because they answer when it suits them. Stay inside the collection and data protection laws of your country and start with a pilot on one group.
- How to tell your messaging-app sales team is underperforming without reading the chatsA weak sales team in messaging apps shows in indirect signals, not in the chats: reply time grows, abandoned conversations pile up, clients go quiet after the second message, promises slip, revenue doesn't follow broadcasts. Gather these signals into a 30-minute review once a week and decide in advance what to do about each one.
