Multi Forecasting Primer

In this topic, find information about the Workforce Management approach to multi-site forecasting in a networked contact center, where some call types and activities are distributed to agents working across multiple sites. It also describes the Genesys approach to multi-skill forecasting, where agents with multiple skills can increase the center’s efficiency by performing multiple tasks within a single timestep.

This topic contains the following sub topics:

Multi-Site Forecasting

A contact center analyst can use Genesys WFM to model a networked contact center, where some call types and activities are distributed to agents working across multiple sites. To model a multi-site environment, follow the steps and guidelines outlined in these sections:

Set Up Multi-Site Activities

These multi-site activities are work activities that are handled at the site (child) level, and in the object tree they appear higher in the hierarchy.

Determine the Total Demand

To configure Multi-Site Forecasting (MSF) properly, you need data to inform your choices. To gather that data, you can configure WFM to collect:

  • Historical Interaction Volume (IV) and Average Handle Times (AHT) for multi-site activities
  • Historical average handle times at the child level

After you build a volume forecast at the multi-site activity level and understand the total demand for this call type across all sites, you can configure MSF for two scenarios:

Option A: Contact centers that do a percentage allocation across their sites

To configure for this scenario, perform these steps:

  1. Split the volume of the multi-site activity to the site level.
  2. Build staffing forecasts at the site level for each child activity.

Option B: Virtual contact centers that do routing based on resource availability, open hours, etc.

To configure for this scenario, perform these steps:

  1. Split the volume of the multi-site activity to the site level.
  2. Build a staffing forecast at the multi-site activity level. (See Figure: Comparing two multi-site scenarios below.)
  3. Split the staffing forecast to each child activity.
Important
The volume split is the required first step, so that the staffing splitting algorithm understands the demand at each site.

Volume Splitting

In a multi-site enterprise, when you split the volume of multi-site activity interaction to the child sites, you must decide which Average Handling Time (AHT) to use:

  • AHT collected at the multi-site activity level
  • AHT collected at the child activity level

To inform your decision, determine if there is a measurable difference in AHT at the various sites in the enterprise. For example, if one site consists of many less-skilled agents (perhaps they are new to their jobs), you may expect to see a longer AHT at this site for some activities. In this case, you would do well to use the child AHT rather than the multi-site AHT.

After you split the volume to the child sites, decide if you want to:

  • Build staffing forecasts for each activity, at the site level
  • Build staffing forecast at the multi-site activity level and then split that forecast to the site level

Be aware, when WFM splits the interaction volume to the child sites, the forecast splitting algorithm considers:

  • Agent skills
  • Contract availability
  • Activity open hours
  • Time zones
  • Agent hire/termination dates
  • Granted, pre-planned items from the WFM Calendar (days off, time off, shifts, working hours, availability, exceptions, and rotating patterns)

In the figure below, you can see model of the contact center environment that WFM uses when splitting volumes from the multi-site activity level to the site (child) activity level.

Volume Splitting Using Percentages

You can specify a percentage to allocate volumes from a multi-site activity to each Child (site) activity or apply a template. The interval can be the entire forecast scenario, weekday, or timestep.

For more information about this feature, see the Web for Supervisor Help topic Forecast > Forecast Scenarios > Volume Split Wizard.

Staffing Splitting

As described above in Scenario B, for virtual contact centers, you can build a staffing forecast at the multi-site activity level and then split that staffing forecast across the child activities. This allows the enterprise to more accurately model a virtual routing environment where there is an efficiency gain in the way that calls are handled. WFM recalculates service objectives at this multi-site level and makes these calculations available in the Performance and Schedule views, and in reports.

When building the staffing forecast at the MSA level, you may specify the indirectly occupied time (IOT) and service objectives.

However, you cannot specify the hourly wage or paid hours a day when building the MSA staffing forecast. Instead, you specify those values during the splitting process, when you split the calculated staffing from the MSA level to the child activity level.

Important
Before you split the staffing forecast from the MSA level to the child activity level, you must first split the volume forecast so that the staffing splitting algorithm knows the resource demand at each site.

The staffing splitting wizard gives you the option to consider the AHT values of the child activities. You can use it to better estimate how to distribute staffing requirements across child activities.

Although the staffing splitting wizard splits calculated staffing by default, it offers you the option to split required staffing.

After the staffing split is accomplished, you can view results data for calculated staffing (and optionally, required staffing) at the child activity level.

You can examine this data at the MSA level or as the sum or weighted average of the child activities, in these views:

  • Schedule Coverage
  • Intra-Day Schedule
  • Schedule Summary
  • Performance views

You can manipulate the MSA staffing results in the same way that you can manipulate child activity staffing. Forecast graphs are also available for MSA staffing.

Multi-Skill Forecasting

A multi-skilled contact center presents an opportunity for increased productivity.

An agent might be idle in a single-skill environment because she cannot answer calls that are queuing for an activity/skill which she may posses—but a skill that the schedule prevents her from using.

In a multi-skilled environment, she can use her additional skills to answer those calls.

Important
A high-load environment does not present much opportunity for increased efficiency, because the agents have very little idle time. However, in an overstaffed environment, agents have more idle time and can use their multiple skills to increase efficiency.

How WFM Supports Multi-Skilled Agents

A multi-skilled agent is qualified to work on multiple activities, and therefore may perform different types of work during a shift.

In a multi-skill environment, an agent might be available for multiple activities during any timestep. That agent can be scheduled to work for an activity for only part of a time interval, and only the fraction of the time period during which she or he works is counted.

Because of this, the value for staffing can be expressed as a fraction. Consider the following example of a 15-minute timestep:

Example: An agent is scheduled to work on Activity A for 10 minutes and for 5 minutes on Activity B. She is counted as 2/3 (or .667) of an agent for Activity A, and as 1/3 (or .333) of an agent for Activity B.

Calculating Multi-Skill Equivalents

Consider the comparison of Single Skill Equivalents (SSE) to Multi-Skill Equivalents (MSE) in the figure below.

The Multi-Skilled forecasting algorithm takes into account how many agents (with their various skill sets) could be available to work on each Activity, as well as how the occupancy of an average agent would be divided among this Activity and the other Activities on which the agent could work.

Figure: Comparing Multi-Skill and Single-Skill Equivalents

When building a schedule, WFM can optionally use the staffing forecast in Multi-Skilled Equivalents (MSEs) while taking into account agents that the schedule is being built for, as well as agents for whom schedules have already been built.

If the MSE option is set, in the Performance views/reports and Schedule views/reports, coverage for an Activity is based on MSEs, calculated from actual agent schedules. See the figure below, which depicts multi-skill gains.
