What If

Use a What If to understand the, often unintended, results of adding or removing overrides. For example, the What If for an override lowering the overbooking shows you that it will increase pricing and LRV. That helps you decide if the override is the best solution.

Thus, we recommend using a What If before saving your overrides, especially for those with a large impact, like pricing, overbooking, and Multiday overrides. And What If can help you with strategic goals, see this best practice.

Notes:

A What If is a simplified preview of an optimization G3 RMS uses the demand forecast (volume and value), the available capacity to sell, your configuration and your interactions (Special Events, overrides) to calculate optimized controls. Optimization output includes pricing for the BAR, Last Room Value (LRV), overbooking and the constrained Occupancy Forecast., comparing the conditions after the override to the ones after the last optimization. If you already saved other overrides since the last optimization and now apply more, a What If compares the impact of all overrides, not just the last one.
The What If option might be grayed out, see Understand When What If is Available.

Steps to Run a What If

Add or remove a Pricing Override, Demand Override, Wash Overrideor an Overbooking Override.
Click What If . Results open in a new window.
Note: the completion time for the What If analysis depends on the number of days it covers. If you saved multiple overrides since the last optimization, What If covers all days impacted by those overrides, including the time in between. The analysis time for this type of scenario may run considerably longer than a single-day override.
Change the displayed data, as needed:
- The default Daily Details view shows Pricing values. Click Overbooking & LRV to display these other decisions.
- Select the Show Old Values checkbox to show values before adding or removing the override.
- To hide or show columns, click to open the menu on the right side of the column headers. Click an available column listed in the window to display or hide it. Visible columns are marked with a dot icon.
Analyze the results. See Data Details below. Click the Excel icon to download all the results to a spreadsheet.
Click Close when your review is complete.
Return to the page where you placed or removed the override. Decide to save or cancel:
- If your analysis of the results confirms the need to add or remove the override, click Save to finalize the override change. Note that you don't finalize the values displayed in the What If.
  - If you added an override, the new override value displays, and an icon indicates the active override.
  - If you removed an override, the override icon no longer displays, but the old override value remains.
  - In either case, the impact on forecasts and other decisions is not calculated until the next optimization cycle. For example, a demand override may lead to a different pricing decision. Changed controls are sent to your Selling Systems Any distribution system, like a PMS, CRS or a Channel Manager, that is used to sell your transient guest room inventory. Ideally, G3 RMS sends all controls to your selling systems, but this may vary based on their capabilities. For some integrations, the selling systems may not include the reservation system that provides with data. during the next intraday or nightly processing. Pricing overrides can be sent immediately by clicking Upload.
- If you are no longer certain that the changes are the correct choice, click Cancel. We recommend that you keep monitoring the situation until you know more, or the situation changes.

Data Details

Net Variance Summary

Begin by reviewing the Net Variance Summary for the overall impact of the change. The Net Variance Summary displays data at the total property and Room Class levels for the changed date, as well as the seven days before and seven days after the change. G3 RMS shows this range because an override for one day may impact surrounding days, due to guests staying over. Keep in mind that the system optimizes all decisions together, so an overbooking override may also change other values like the Occupancy Forecast The number of rooms (or percentage of the total number of rooms) that G3 RMS expects the property to achieve for the period. For the calculation, see the Demand and Wash - Overview topic (under Data Details). and pricing.

Arrows indicate the changes cause either an increase or decrease in the measured values for the period. Increased values also display in green, while decreased values display in red.

The Net Variance Summary displays the following data:

Column	Description
Room Class	The Room Classes affected by the change.
Occupancy Forecast %	The change to the occupancy forecast as a percentage, at the property and Room Class levels.
Revenue	The change to the expected revenue at the property and Room Class levels. Most What If results after adding a decision override will show lower revenue because G3 RMS calculates the optimal decisions to maximize revenue based on the available demand and your inputs. If you believe that is incorrect, consider what exactly you know that the system does not know and share that input with the system by influencing the system’s forecast rather than changing the controls. For example, override the cost of walk or wash rather than overbooking, and review demand by Forecast Group and your rate shopping setup rather than overriding pricing. Sometimes you may expect and accept lower revenue, for example, when you add a floor pricing override to protect the rate of a contracted group that is currently higher than BAR. In that case, compare the impact of the override against the cost for lowering the group rate.
Occupancy Forecast	The change to the occupancy forecast in the number of rooms, at the property and Room Class levels.
RevPAR Revenue Per Available Room. The total room revenue divided by the total number of rooms (capacity). For the capacity definition, see the At a Glance - RevPAR topic (under Data Details).	The change to the Revenue per Available Room at the property and Room Class levels for the period.
ADR	The change to the Average Daily Rate at the property and Room Class levels for the period.

Profit Data

If you enabled Profit or Channel Optimization, the Net Variance Summary also shows the changes in Profit metrics:

Data	Description
Profit	The calculation depends on data that you provide. G3 RMS can consider profitability of guest rooms (based on servicing, channel costs, etc.) and profitability of other revenue streams. For current dates, G3 RMS estimates the profit based on occupancy on books and Occupancy Forecast The number of rooms (or percentage of the total number of rooms) that G3 RMS expects the property to achieve for the period. For the calculation, see the Demand and Wash - Overview topic (under Data Details).. For past dates, the system estimates the profit based on the final number of rooms occupied.
ProPAR	Profit per available room. ProPAR equals the profit divided by capacity (based on property's selection, either Physical Capacity The total number of guest rooms at a property, including out of order rooms. or Effective Capacity The hotel's physical capacity minus the out of order rooms., and is comparable to RevPAR Revenue Per Available Room. The total room revenue divided by the total number of rooms (capacity). For the capacity definition, see the At a Glance - RevPAR topic (under Data Details)..
ProPOR	Profit per occupied room. ProPOR equals the profit divided by the number of occupied rooms and is comparable to ADR Average Daily Rate. Room revenue divided by the number of rooms of occupancy..

Daily Details

The Daily Details pane shows the decisions for the override dates. Compare the Old values, prior to adding or removing the override, to the New values, which will be the new results after you save the change. Increased values display in green, and decreased values display in red.

Higher pricing decisions in a What If may also mean lower occupancy forecasts. G3 RMS understands that at a higher price point, there may be less demand available than at the lower one.

Daily Details displays the following data:

Column	Description
Date	The dates for which an override was added or removed.
Room Class	The Room Classes affected by the change.
Decisions, Old and New	The Old column refers to the current value. The New column estimates what the decision will be after optimization and after the override change takes affect. Arrows indicate the changes cause either an increase or decrease. Increased values display in green, and decreased values display in red.

Best Practices

Understand When the What If Option is Available

What If is not available:

If your G3 RMS subscription doesn't include it.
When you override wash at the individual group level. It is available for wash overrides at the Forecast Group level.
When G3 RMS sends decisions to your selling systems and displays an upload icon before the System Date.

Use What If to Measure Strategic Goals

If you know how much extra business a special promotion or marketing campaign delivers, measure that business against what the system currently predicts. Then compare the revenue gain against the marketing costs.
A similar analysis can review a business mix change to compare the additional revenue from the targeted market segment against the increased cost of sale or displacement of business from other segments.
You can also use the What If function to examine less frequent situations. For example, use it to help determine the best and worst case scenarios on the impact to your business if a neighboring hotel is going into renovation.
