Pricing House Cleaning Assignments
HCA Statistical Analysis with Practical Applications
15.The Effect of Operating Profiles on Cleaning Times
15.1. |
Individuals vs Teams: The analysis does not relate to individual cleaners, only teams of cleaners. We imagine the man-minutes involved for individuals might be different than for teams, and show more variability. Since the test company generally employs team cleaning, the data for individuals was not available.
|
15.2. |
Constraints — Fixed vs Variable Team Size: In factoring the daily schedule, our experience shows that constraints can have a significant impact on a company’s long-term profitability. As degrees of freedom are reduced, the natural reaction for any operating manager is to hire additional employees to meet the needs for the busiest days. As our analysis shows, the overhang associated with carrying these extra employees on slower days can be costly in a sneaky way, because professional cleaners tend to balance their work days to return at uniform times. So unless a company manages to measure efficiency by day, an inexperienced operator might mistakenly associate regular return times with full utilization.
|
15.2.1 |
A particular clean day of the week can be the mostly costly constraint, and can only be avoided by managing clients and their expectations. Failure to limit the continuous flow of customers to Fridays can cause, in its extreme, Fridays to account for 50% of total weekly revenue.
|
15.2.2 |
The second most important constraint is “First Clean of the Day” and the combined two, “First Clean on Friday” can quickly cause a schedule to become quite costly to solve.
|
15.2.3 |
Our experience shows that constraints can frequently be managed on the busiest days by breaking teams into more groups of smaller individuals. Demonstrating flexibility in team sizes can significantly improve profitability, because it allows a company to meet the demands of its busiest days with a net smaller number of individuals than might otherwise be necessary, while still allowing for larger team sizes on slower days.
|
15.2.4 |
And larger average team sizes on slower days allows a company time for training; aside from time, it also provides opportunities to diversify personnel, for evaluations and training, among a larger number of supervisors per week for each cleaning professional. Our experience shows that, over time, such practices can significantly enhance overall quality of service and reduce client churn.
|
15.2.5 |
Flexibility in scheduling represents another significant advantage which independent house cleaning companies have over many franchise maid services.
|
15.3. |
Compensation Schemes: Compensation schemes can affect results in terms of both quality and efficiency. Although this analysis does not compare the man-minutes required to clean homes under alternative compensation schemes, our analysis of psychological factors included in the “Execution Factors” section does provide some hints about the effects. We mention the issue of compensation schemes here because our experience has shown that it does directly impact the time it takes to clean a home.

15.4. |
Work Scope: It might seem too obvious to mention, but it takes more time to clean a house thoroughly than it takes to clean it fast. The reason we bother mentioning it is because any company which uses the HCA Pricing Tools has to consider how their company compares to the test company. As a comparison, for the dataset used in this analysis, the scope favors thoroughness over speed. So if you are the fastest cleaner in the West, you might want to consider tweaking the formula downwards a bit to yield lower prices and allow for this difference.

Man-Minutes and Employee Training: Our experience shows that employees can be trained to clean more efficiently. There are marginal returns in doing so. Most of the benefits can be derived from having a Team Leader demonstrate the basics through on the job training during a new employee’s initial days in the field. As a result, the HCA Training Designer is generally used to educate professional cleaners about company policies, primarily with a view to avoiding damages and losses.

Man-Minutes and Employee Churn: Experienced employees have the ability to clean faster than less experienced employees, so employee churn can significantly impact cleaning times.
|

15.7. |
Arrival Time – The too much work syndrome: our experience shows that employees work towards returning to their homes at a predictable hour each day. Often, this can relate to their children’s school or daycare schedules and associated constraints. Arrival time at the customer’s home and revenue per hour are used to identify those days during which employees might determine they have too much work. Our experience shows that on such days, employees simply work faster, or cut corners, to contain the work day within the regular work hours, resulting in higher efficiency but more customer complaints.
|
||||||||||||||||||||||
15.8. |
Arrival Time – the Not-enough-work Syndrome: further to the point above about predictable return times, our experience shows that employees tend to stretch the allotted work to meet their own expectations for return times. This can easily be accommodated in a legitimate and subtle way just by cycling in a little extra cleaning for each house, “Let’s clean baseboards today for both of these houses, since we had a cancellation.” While it may sound faultlessly virtuous, it does beg the question about the condition of said baseboards in the event of no cancellations. Most importantly, an operator can fatally compromise profits by allowing the “not enough work syndrome” to regularly prevail.

15.9. |
Man-Minutes and Central Dispatch: Central dispatch can significantly contribute to the elapsed time with respect to the overall work day, particularly for drive time. The advantage of central dispatch is in schedule balancing, control, and provisioning. Most scaled maid services suffer the marginal time associated with central dispatch.
|

15.10. |
Team Size and Travel Time: a significant point about team size which has not been captured in our analysis relates to team size and travel time. While this may be obvious to an experienced operator, it is, nevertheless, sufficiently important in terms of its economic effect on a house cleaning company to require some discussion. In order to optimize scheduling and regularly make profitable decisions about team size, an operator must factor in drive time.

16. Variables Considered, but Excluded
16.1. |
Cleaning Equipment and Supplies: For a professional house cleaning company, the costs of labor is so overwhelmingly important that the per assignment costs of cleaning equipment and supplies is simply lost in rounding. We’re not saying that it is not worthwhile to carefully manage such costs, but rather that we have chosen not to attempt to allocate them by assignment.
|
||||||||||||
16.2. |
Bedrooms, Common Rooms, and Laundry Rooms: these areas of a house are highly correlated with square feet. Including statistics for these areas of a house provides almost no meaningful predictive value to the model.
|
||||||||||||
16.3. |
Clutter Factor: measures the extent and orderliness of clothes, toys, and paper, and the impact such items have on Clean Times. A home cluttered with clothes, toys or paper can take significantly more time to clean than an uncluttered home. While the concept seems to have merit based on our experience, we found it very difficult to apply because users invariably mixed clutter factor with Lifestyle Factor. Indeed, this was clearly demonstrated during the statistical analysis – the factors proved to be highly correlated and the clutter factor was shown to have a low predictive value, and has been removed from the equation.
|
||||||||||||
16.4. |
Decoration Factor: measures the extent and intricacy of a Household’s decoration and the impact the household’s decoration has on Clean Times. An ornately decorated home takes longer to clean, particularly to dust, than an undecorated home. A minimalist would have a negative Decoration Factor, while an art collector might have a high Decoration Factor. While the concept seems to have merit based on our experience, the factor was shown to have an unacceptably low predictive value, so it has been removed from the equation.

17.Hourly Rates |
|||||||||||||
17.1. |
The default rates used in the HCA pricer are not suggested rates. As with all the default values, they are set only to allow the pricer to work if a user should inadvertently fail to input a value.
|
||||||||||||
17.2. |
Each operator sets his or her own targeted hourly rates for initial cleaning assignments and recurring assignments by taking into account a number of unique factors which may include their local pay rates, overhead costs, and target profit margins.
|
||||||||||||
17.3. |
For an operator of a professional house cleaning company, setting an official target hourly rate at a level which is higher than the Company’s minimum acceptable rate, if flexibly applied, can allow the Company to price assignments in a way which appeals to a wider range of consumers, while still allowing it to capture the maximum total consumer surplus. To appreciate this concept, consider the figure below. The Company’s own cost structure and constraints necessitate setting prices at the blue line to avoid losing money. To remain in business and earn a producer surplus (a profit), an operator can fix its price at the Equilibrium price. But to optimize profits, an operator might retain some flexibility in pricing. This is can be done by taking into account each consumer’s price sensitivity (yet another reason to perform in-home visits, instead of quoting by phone!) when deciding whether or not to provide a quoted fixed price above the equilibrium price, or at the equilibrium price.
