Ability of the employees. 2. Clarity of Organizational duties. 3. Evaluation of employees. 4. Improvement of organization's environment.

Literature Review
Baladehi and Saleh in a research that was done descriptively and by survey method, proceeded to investigating succession planning and its relation with the way of leadership related to commanders and managers 9 . Statistical population in this research was working managers and commanders in occupational place of 17 and up to this related to police command of Mazandaran province that for choosing statistical sample according to limitation of statistical population, all-counting methods were used. Collecting data has been done by librarian information and using questionnaire. Standard questionnaire related to succession planning of Kim with 43 questions that after idea, final questionnaire according to studied society and its features (regional) 36 questions were tempered and chosen and includes three indexes of organizational factors aspect with 17 questions, personal factors with 7 questions and process aspect with 12 questions. Stability of this questionnaire was tested by Cronbach's test 0.85. For analyzing data two methods of descriptive statistics (variables of gender, marital status, educations) and inferential statistics (correlation coefficient, regression) with SPSS software were used 10 . Results indicated that there is also relation between succession planning components (organizational, personal and process) and type of leadership related to commanders and managers that among them, process factors (0.467) had the highest correlation coefficient and personal factors (0.434) had the least correlation coefficient. Tsai in a study has proceeded to investigating the effect of succession planning in family businesses on organization's performance according to the role of moderating related to criteria of human resources 11 . Results of the study indicated that succession plans of managers have meaningful effect on organization's performance. Also, other results showed that criteria of human resources doesn't have meaningful effect on the relation between succession planning and managers performance. Minichilli and colleagues in a study proceeded to the investigation of the relation related to succession planning mechanism of managers and performance of the company 12 . In this research, performance of the company was assessed according to financial and nonfinancial issues and the results of the research showed that managers succession planning have meaningful relation with two financial and non-financial aspects of organizational performance. Also, they concluded that organizational environment can also have meaningful effect on the relation related to succession planning and performance of the company. Crumpucker and colleagues in an investigation as the relation of generation with succession planning stated that the main goal of their studies is the investigation of the relation between especial aspects of succession planning with changing generations in financial and non-financial organizations 13 . In this study, 12 financial companies and 28 non-financial organizations have been used as statistical society. Results of the study indicated that there is a meaningful relation between the aspects of succession planning and changing generations.

Statistical population of the present research includes all employees and personnel of Shoushtari Maternity Hospital in Shiraz. According to this issue that the amount of statistical population estimated as 240 and also the results of Cochran formula, 169 people were chosen as final samples of the research. On the basis of goal, this investigation is practical and according to the way of collecting data is descriptive-survey and on the basis of the way of execution it can be understood as correlated. In this research for assaying investigation variables, questionnaire has been used.

Analyzing and testing research hypotheses investigating the condition of variables distribution by using Kolmogorov Smirnov test
Null hypothesis: Data is obeyed normal distribution. Alternative hypothesis: Data is not obeyed normal distribution. According to Table 1, it can be said that as meaningful levels of all indexes are more than 0.05 criterion, these indexes are obeyed normal distribution.    (Table 5), the amount of correlation between two variables of succession planning and evaluating employees equals to 31.0 and because the meaningfulness level of the 0 test is less than 0.05, so null hypothesis is not accepted and there is a meaningful relation between two studied variables. So, by using regression test, we proceed to investigating the condition of the relation. As the beta coefficient is positive, the relation between two variables is direct. Determination coefficient showed that 9% of changes related to evaluating employees is explained by succession planning. In plans of succession planning for distinguishing and determining capabilities, according to these activities, some evaluations are done. Furthermore, on the basis of the announced results related to plans and courses of succession planning, some results persuade managers and especially human resources section for performing some evaluations that the results of these evaluations may lead to periodically holding evaluation in intended organization. The result of investigating this hypothesis agrees with the studies of Minichilli and colleagues, Tsai. 5. Hospital managers succession planning has meaningful effect on: The seventh hypothesis: Improving organization's environment.

Null hypothesis:
Doesn't have improving organization's environment. According to results (Table 6), the amount of correlation between succession planning and improving organization's environment equals to 312.0 and because the meaningfulness level of the 0 test is less than 0.05, so null hypothesis is not accepted and there is a meaningful relation between two studied variables. As the beta coefficient is positive, the relation between two variables is direct. Determination coefficient showed that 4.8% of changes related to the clarity of organizational duties are explained by succession planning. The existence of proper and favorable working conditions on the basis of working hygiene and anatomy of people are prerequisites of doing succession planning for distinguishing weak and strong points of employees and their improvements. In other words, providing lack of the existence of proper working conditions and organizational environment, working quantity and quality of people cannot be assessed and be compared with working need and distinguish are this people prepared for receiving higher working positions or no? So, proper organizational environment is one of the requisites of rule-governed succession planning and also during these courses, if professional people do not observe environment's accordance with the type of people work and investigating competency of people in environments, assess the number of faults and defects of organizational environment and report to managers. The result of investigating this hypothesis agrees with the studies of Minichilli and colleagues, Tsai.
