The technology of valuation of the staff activity effectiveness

The main purpose of awarding bonuses system at enterprise is increase of successful employees' motivation and their labor productivity growth, and amount saved of wage fund of workers who are not efficient. [1]

In modern conditions the system of employees' activity motivation is based on labor index of relevant organization departments while personal employee’s contribution to these targets achievements is not considered. [2] The given system suggests that the employee's premium should depend not only on the results of his or her organization department work, but also on his or her personal results and on his or her safety measures taking.

The effectiveness criteria are the optimal term of work finishing at the lowest cost with reference to mining preparatory sections. [3] Any of these viewed effectiveness criteria should be examined for compliance with the specific conditions of mining industry during the process of natural resources storage preparation.

The main criterion of qualified natural resources storage preparation (K_prep) is terms minimum deviations of new complex-mechanized bottoms exploitation from working-off finish terms of a mine section. This deviation allows minimizing mining production losses [4,5]:

(1)

where T_work-off is working-off time of a pillar being under exploitation in terms of days;

T_prep is time of a new pillar preparation in terms of days;

T_pf is time of preparation and final operations in terms of days;

D_fact is factual volume of mining excavation of a mine in terms of a current year;

D_prod is a real volume of coal production realization in terms of a current year.

The choice of time criterion is based on the main purpose of mining preparing subsystem, which is provision of continuous mining works, that is determined by prepared for working – off pillars storages (Z_ready,thousands per ton) which have to provide yearly coal production work of a mine (D_fact, thousands per ton ) or to exceed it [6].

Optimal terms of preparatory works are those which provide timely and qualified stopes preparation that means that the complex criterion is followed:

(2)

where K_opt is criterion of optimal preparatory works terms;

is mineral reserves, ready to work;

C_worki is current costs on I -type works of a new stope preparation.

The representatives of working specialties, as a rule, have low abilities to abstract logical thinking; however their visual-figurative and concrete-active abilities are well developed so they are successfully engaged in physical labor, creating wealth with their hands. There is no need to appeal to their logic, trying to explain complex calculations of labor accounts. All calculations should be simple and based on such indices as the execution of a plan, maintenance of discipline and safety measures.

To evaluate mining preparatory sections effectiveness per month the following indicators, according to working out criteria are suggested:

- duration of preparatory excavations, ensuring the execution of a timely plan of necessary volume of ready-to-indentation storages preparation;

- the cost price of 1 per meter( PM) of output.

Each of the chosen indices is a component part of a purpose formulation. When there is no verb pointing out that should be done with the index (to increase, to decrease etc) in a formulation, the index is given a certain direction:

- less is better – in cases when the goal is to decrease expenses, program execution time, etc;

- more is better - when it is necessary to increase such indices as volume of output, extension of carrying out of preparatory excavations, profits, etc;

- exactly is a qualitative criterion of direction, is used when it is necessary to find out whether the goal is achieved, or the project is introduced, etc.

As applied to mining preparatory subsystem the indices directions may be the following: preparatory excavations duration is "more is better» or "exactly" depending on excavation development conditions at the enterprise and the level of expenses; cost price of 1 per meter (PM) of output is “less is better”.

The indices, as a rule, have different weight, as the contribution of each of them to the purpose achievement of an enterprise can vary. The authors’ suggested specific weight indices, characterizing work effectiveness of mine preparatory subsystem per month are given in Table 1.

Tab 1 - specific weight of mining preparatory subsystem work effectiveness indices per month.

Index name	Specific weight, %
1. Duration of preparatory excavations, ensuring the execution of a timely plan of preparation of necessary ready-to-indentation storages volume, m .	70
2. Cost price of 1 per meter ( PM) of output, rub/m	30

It is necessary to set a target value (a plan) for each index to estimate organization department's activity effectiveness.

The example of mining preparatory section’s work effectiveness calculation per month is given in Table 2.

Tab.2 Mining preparatory section’s work effectiveness calculation per month

Index name	Target value	Factual value	Specific weight, %	Level of achievement, %
1. Duration of preparatory excavations, ensuring the execution of a timely plan of preparation of necessary ready-to-indentation storages volume	300 m	320	70	107
2. Cost price of 1 per meter (PM) of output, rub/m	35000 rub/m	33000 rub/m	30	106
Section’s work effectiveness,%

The calculated value of the section’s work effectiveness can be either the premium per sent or one of the values that affect the rate of the premium and stimulate workers to its achievement.

What is more, it is possible to use execution boundaries that are the minimum acceptable level of execution, which is considered to be completed and maximum level of execution, when estimating the organization department's activity effectiveness. [7] The execution boundaries should be set for preparatory sections. The example of execution boundaries of work effectiveness index of mining preparatory section per month is given in Table 3.

Tab 3 - Execution boundaries of work effectiveness index of mining preparatory section per month

Index name	Index directivity	Target value	Specific weight, %	Minimum	Maximum
1. Duration of preparatory excavations, ensuring the execution of a timely plan of preparation of necessary ready-to-indentation storages volume	More is better	300 m	70	70% 210 m	130% 390 m
2. Cost price of 1 per meter (PM) of output, rub/m	Less is better	35000 rub/m	30	90% 31500 rub/m	120% 42000 rub./m

The execution boundaries can be either limits or stimulators. Providing that upon expiration of the period given for goal achievement the index with directivity "more is better" is below the minimum or an index with directivity "less is better" is above the maximum, the goal is considered unreached. In this case the worker’s premium to is not calculated. Increase of maximum index boundary with directivity "more is better" or decrease of minimum boundary involves extra (higher) reward, or stoppage of premium growth. In the first case we can speak about up-multiplier and employee's premium will grow even faster than before reaching the maximum boundary index; in the second case there is no need to speak about the maximum premium level established in case when high productivity is not demanded. Between minimum and maximum level of index achievement the premium is set at 1% for each per sent of exceeding minimum value of index.

The example of calculation of mining –preparatory section employee’s premium with usage of effectiveness indices boundaries executions per month is given in Table 4.

Tab.4 Calculation of mining preparatory section employee’s premium with usage of effectiveness indices boundaries executions.

Index name	L	C m	The size of employee’s premium
Target value	300 m	35000 rub./m	15000 rub.
Specific weight of index, %	70	30
Minimum value of index	70% 210 m	90% 31500 rub./m
Maximum value of index	130% 390 m	120% 42000 rub./m
Premium at target value achievement	10500 rub.	4500 rub.	15000 rub.
Premium at minimum value index	70% 7350 rub.	120% 5400 rub
Premium at maximum value index	120% 12600 rub.	70% 3150 rub
Factual value of index	320 m	33000 rub/m
The factual size of employee’s premium	11200 rub.	4770 rub.	15970 rub.

Herewith, besides a premium depending on index of organization department’s work efficiency, the use of premium depending on a personal employee’s working activity effectiveness is suggested.

Mining employee’s activity effectiveness depends on the following indicators:

1. Quantity of met challenges, performed tasks and operations;

2. Quality of the performed tasks, functions, operations;(correspondence to production technology, absence of mistakes);

3. Time taken on tasks, functions, operations (timely or pre-term execution)

4. Safety measures taking.

It is recommended to establish one’s own share and scale due to personal activity effectiveness index. Having determined maximum size of an employee’s premium at the rate of 100% personal activity (at the given example – 15000 rubles) one can calculate a size of a premium received for every premium index achievement. That makes a system easy for employee’s comprehension and provides interested motives (Table 5).

Tab.5 Matrix of employee’s personal work effectiveness index and size of premium at different effectiveness levels.

Index name	Specific weigh %	Scale			size of a premium at the rate of 100% effectiveness
1	2	3
1. Quantity of met challenges, performed tasks and operations	15	Low No premium	Medium 60% of a premium	High 100% of premium	2250
2. Quality of the performed tasks, functions, operations	25	Low No premium	Medium 60% of a premium	High 100% of premium	3750
3. Time taken on tasks , functions, operations	10	Most terms are not fulfilled No premium	Fits the plan 60% of a reward	Less than that of the plan, 100% of premium	1500
4.Safety measures taking	50	Violation of safety measures No premium	No violation 100% of premium		7500
Size of a reward at the rate of 100% effectiveness	100% / 15000 rub.				15000 rub.

Any safety measures violation leads to the enterprise’s losses in terms of production suspension, equipment failures, necessity of employee’s compensations payment. Especially these losses are for mining enterprises. Decrease of losses leads not only to decrease of such kind of costs but as well at to work efficiency increase. All these factors form a definite economic profit of the enterprise, which results not only in getting a profit but also in increase of investors’ and employees’ interest.

Since persistently high productive work can be done only in case of safe labor conditions, excluding traumas and accidents, the authors recommend giving the most of the specific weight to the “safety measures taking” index in the matrix of individual effectiveness indices.

The example of mining employee’s individual part premium calculation at the rate of medium individual efficiency indices is given in Table 6.

Tab. 6 Example of mining employee’s individual part reward calculation at the rate of medium individual effectiveness indices.

Index name	Specific weigh %	Scale			Size of a premium at the rate of 100% effectiveness
1	2	3
1. Quantity of met challenges, performed tasks and operations	15	Low No premium	Medium 60% of a premium	High 100% of premium	1350
2. Quality of the performed tasks, functions, operations	25	Low No premium	Medium 60% of a premium	High 100% of premium	2142
3. Time taken on tasks , functions, operations	10	Most terms are not fulfilled No premium	Fits the plan 60% of a reward	Less than that of the plan, 100% of premium	900
4.Safety measures taking	50	Violation of safety measures No premium	No violation 100% of premium		7500
Size of a reward at the rate of 100% effectiveness	100% / 15000 rub.				11892 rub.

This system is to substitute existing system of deprivation of premium which works only as a set of punitive measures after committing violations that slightly effects prevention safety measures violations. The suggested system must stimulate for safety but not to punish for violations.

Herewith, without deprivation of premium thy system can not be full. But deprivation of premium has to relate first of all to organization’s managers as they do not provide safe labor conditions or deliberately force the employees to violate safety measures for production indices increase.

A foreman miner is a key person in a shift whose target function is to organize staff effective work and to provide safe labor conditions. Main factors of safe production, as foreman miners consider, are the following: one’s carelessness, violation of technologies and works organization, physical and moral depreciation, careless attitude to work, execution of a plan at any cost, violation of safety measures, discordance of actions [8]. As minimum four of these six factors are under foreman miners’ charge. Therefore, in case of safety measures violation caused a trauma of any heaviness extent it is suggested to deprive a foreman miner of 100% individual premium and to deprive a mining section head of 50% individual premium.

A total size of mining-preparatory section employee’s premium is a sum of a premium depending on organization department’s work effectiveness and a sum of a premium depending on employee’s individual work effectiveness.

Despite subjectivity of suggested employees’ activity the presented premium system has the following advantages: opportunity to compare department employees’ effectiveness; opportunity to do monitoring of particular employees and subdivisions in dynamics; appliance to all professions and posts; comparing employees’ estimates one can come to conclusions about the heads’ ruling style and to reveal ineffective areas in subdivisions; motivating employees to safety measures taking; adaptability to being used for employees’ activity estimation in all subdivisions of the enterprise and allowance to lead their data to a single format.
