The minimum efficiency is the least of allowed ("threshold") values for any indicator of efficiency. When this value is not reached the indicator is considered as "failed".
The minimum efficiency is used to insure from situations when one of the indicators is literally "extended" due to another, preventing the general average mark to be correct.
Example 1. A new manager was employed in the sales department. His work was evaluated by two efficiency indicators: on "turnover" and on the "number of deals per month", which converged into a general efficiency. The standards values for each indicator: USD 27 000 for turnover and 12 deals per month, accordingly. Both indicators have the same significance (same weight).
The basic part of the salary was defined to USD 250, the variable part (premium) - USD 700 (when the standard tasks are fulfilled to 100%).
Thus, the salary was calculated using the following formula:
Total salary = Basic part (USD 250) + Premium part, where
The premium part = USD 700 х The general Efficiency
The manager chronically struck not more than 4-5 deals per month, and his turnover was "extended" due to large Clients. His efficiency of turnover sometimes reached 110%.
- Efficiency on the number of sales = 4 deals/12 deals = 0,33 or 33%.
- Efficiency on turnover = USD 30 000/USD 27 000 = 1,1 or 110%
- Since the weights" of the indicators are equal, without considering the minimum efficiency, the average total efficiency = 72%
- And the total salary = USD 250 + USD 700 х 72% = USD 754.
Amazing but fact: in many companies, a manager who struck only 33% of the standard value of deals, gets these USD 754. Though any pupil at a school, who fulfilled only one-third of the task, would simply get a two and no-one would give him “even a part of the task completed, in general”.
Of course, if the manager would have struck an abnormally low amount of deals (for example, one or two), this would have immediately been noticed. But in a real business, the main losses are made by the employees whose weak work is not noticed – especially those whose efficiency is "average" (a work of 50% is already absurd, not speaking about one-third of it, right?). But ironically, such employees pass unnoticed and as a result in many companies are filled with well-paid poor workers. And poor managers try to get them "motivation".
We shall continue with the same analogy, if a pupil was absent for 5 classes out of 10 of Algebra and 1 out of 10 for Geometry, most probably his knowledge about these subjects is minimum but the "average presence value" (70%), if used as an evaluation criteria for anything, would be foolish.
And if a sales manager makes big deals with a pair or three Clients and "dynamites" the Company for the rest of the month – he is doing the same thing as this pupil.
The minimum efficiency insures from such an erroneous evaluation.
If one of the indicators does not reach the "threshold value", then the general efficiency is equal to:
- Option 1 ("extreme") - towards "0" (i.e. he does NOT get any reward at all).
- Option 2 ("standard") - towards the least value of efficiency.
Let’s introduce a minimum efficiency in our example. Let the “threshold value” for each indicator be equal to 85%.
Then the general efficiency
- for Option 1 will be equal to 0, i.e. the total salary of the manager will be 9000 rubles (he gets only the basic part),
- for Option 2 it will be equal to 33% (the least indicator), i.e. the total salary consists of USD 250 + USD 700 х 33% = USD 481.
For each enterprise, the minimum efficiency has its level and is defined by the technology of work, but even for the most "rubbish" technology, it should not be less than 70%. In such a case where the employee does not reach the minimum efficiency systematically, it is recommended to make sure – are the standards too high. If they are not too high, it is better to fire the employee since the stalling at the company in some cases can be well felt.
But attention: if the threshold of the minimum efficiency is quite high (higher than 90%) and the punishment for that is quite severe(option 1), then the employee will have good reasons to invent different treacheries and shortcuts, as in example 2, described below or others, but do not show any ideas for the improvement of results.
That is why, using a combination of a high threshold for minimum efficiency (higher than 90%) and a limited option 1 is not recommended. Yes, it is not logical when the "threshold" is equal to, or almost equal to, the task.
Example 2. In a company dealing in equipment in the segment B2B, managers of sales set a relatively high basic part of the salary but also a high minimum efficiency – at the level of 100% So losing the reward was easy (when the threshold is not reached, premium part is not paid).
The thought of the management was as follows: "We require much, but we pay well".
As a result, when the employees understood that they do not reach the plan by literally a few percentages – they called the Clients and asked them to make payment not in the current month but for the next one. Thus for the current month, they were satisfied with the constant part of the salary (since as told before, it was not small) and all the deals were delayed in order for the reward in the next month to be guaranteed even for a low number of deals.
Let’s now tackle a more difficult example, when the task occurs on another system level.
Example 3. The Supervisor of a trading chain is responsible for the work of many shops.
The total efficiency of the whole chain is calculated considering the indicators of general efficiency of each trading spot (which calculates: the revenue of the shop, the turnover of the products, the qualitative and net price of non-liquids/ grading/ expired products etc.).
As a whole, the supervisor of the chain had a good result. But this was due to the best shops. Some shops were simply unprofitable; however the supervisor did not work on their development or their closure. What to do?
We set up a minimum efficiency. Here also, we have 2 options:
- Option 2 ("standard") – the same as in the above-mentioned example.
- Option 3 ("complex") – it calculates the general and the worse values.
Option 2 dictates us the rule: if one of the shops (for the general indicator) does not reach the minimum threshold, then the general efficiency of the supervisor of the chain is to be equated to this (low) value.
Option 3 a little more "liberal" than Option 2. It takes into account the probability that getting an improvement in the existing matters of the shop might require many months of work. That is until the reorganization is not made, its efficiency (in the current state), actually, cannot reach the target standard values.
It occurred that there is a risk that the supervisor of the trading chain (after seeing that some shop does not reach the minimum efficiency, and the duration to "make it see reason" is long) will stop working for a result as a whole, and will stop controlling the efficiency of the work of other shops. Since his total efficiency will be equal to that of the worst shop in the chain anyway.
Option 3 gives an opportunity to avoid such demotivation. The total efficiency of Option 3 considers both the "general" and the "worst" efficiencies and is calculated the following way:
For example, the shop consists of 5 shops.
They are all equal in significance (i.e. the "weight" of each is equal to 20%), and the efficiencies for the current month are as follows:
- 86% - for the first shop,
- 93% - for the second shop,
- 54% - for the third shop (the worst value),
- 110% - for the fourth shop and
- 96% - for the fifth shop
1. First we define the general efficiency of the chain by considering the general efficiency of each trading spot and its “weight”.
General efficiency = (86% + 93% + 54% + 110% + 96%) х *20% ("weight") = 87,8 %.
2. Then we find the worst value. In our example, it is 54%.
3. Now we calculate the total efficiency (considering the general and the worst efficiencies).
Their "Weight" in this case is equal, that is why Total efficiency = (General efficiency + Minimum efficiency) / 2 = 71%.
Obviously if no shop "failed", we could have limited section 1.
For example, let the general efficiency of the third shop be equal not to 54%, but to 90%. Then the Total efficiency of the chain would be equal to the general – we do not have any "failure", correspondingly, there is nothing to be done about it.
General efficiency = (86% + 93% + 90% + 110% + 96%) х *20% ("weight") = 95 %.
Let’s make a summary:
- If we would have used a minimum efficiency in the third example, the total efficiency would formally have been 87,8% and it would not have reflected on the state of matters, since one of the shops in the chain "failed".
- If we use a minimum efficiency and then follow Option 1, the total efficiency would be equal to 0 – this is hardly correct in this situation. If we use a minimum efficiency and then follow Option 2, then the total efficiency would be equal to 54%. How bad this option is, has been described in the above-mentioned.
- If we use the minimum efficiency and then follow Option 3, then the total efficiency would be equal to 71%. This option should most likely be used here.
- If there were no "failures", the total efficiency would be 95%.
Example 4. As compared to the situation described in example 2, the variable part of the salary of a manager responsible for sales in another company, also working in the segment B2B, was much higher than the constant part, and it was dependent on two indicators:
- Efficiency of contacts,
- Efficiency of sales.
Efficiency of contacts considers the number of telephone calls and meetings with the Clients. This indicator is quite important since we need to differ the situations when: there are no sales, since nobody worked with the Clients, or there were many contacts and telephone calls, but still, there are no results.
Obviously, the indicator "Efficiency of contacts" still has less "weight" than the indicator "Efficiency of sales".
For example, it is defined that:
- The Efficiency of contacts "weighs" (has significance) of 20%,
- The Efficiency of sales "weighs" 80%.
What will happen if during an accounting month, the manager reaches the minimum efficiency for any of the indicators which affects the variable part of the salary (Which let me remind you, is much higher than the constant part of the salary)?
Let’s suppose that the value of the minimum efficiency is - 85%.
Suppose that for a specific month:
- The efficiency of contacts was 70%, which is lower than the threshold value, and
- The efficiency of sales was 99%, i.e. the factual result is not only higher than the threshold value but is almost equal to the standard.
Let’s consider all three of our Options:
- For Option 1 the general efficiency will be equal to 0, which obviously does not concord with the facts, in this case,
- For Option 2 it will be equal to 70% (the least value), but this indicator has a small weight and will the general efficiency correctly equate to it, given that the value of the second indicator (which has a big weight) is moreover very high?
- For Option 3 the total efficiency comes up to 81,6%.
- General efficiency = 70% х 20% + 99% х 80% = 93,2%.
- The Worst (minimum) value = 70%
- The total efficiency (considering the general and worst values)
Total efficiency = (General efficiency х + Minimum efficiency) / 2 = 81,6%.
In this case, we can easily choose Option 3.
By the way, Option 4 also exists for unequal values:
- If the employee does not reach the threshold value for an "important" criteria, we can equate the general efficiency to the "worst" value – analogous to Option 2.
- If he still does not reach the threshold value for "unimportant" criteria, then the result of this criteria can be "nullified". Then the General efficiency will be equal to the "important" value.
For the case described in the example 4, it means that the General efficiency will make up 99%. However, if the apportionment was inversed:
- Efficiency of contacts would be of 99%, and
- Efficiency of sales would be 70%,
Then the General efficiency would be 70%.
Based on that account, we shall make a tabulated summary for choosing the Option to define general efficiency when the minimum efficiency is set up.
