The importance performance analysis is a simple and condensed analytic method for decision making based on the level of performance or satisfaction. Many researches already have witnessed usefulness of the importance performance analysis, but it also has some drawbacks from the statistical points of view. In this article, some additional techniques dealing the importance performance analysis are introduced and it is shown that these techniques would turn out to be very informative. The importance performance analysis uses the arithmetic average as the main statistic, but by the use of the median, the frequency and the cluster analysis it is shown that the importance performance analysis can be carried out with more crucial information. In addtion to that, it is demonstrated that the combination of the analytic hierarchy process and importance performance analysis could enable more reliable decision making.

Business analysis is a key factor of project success or failure in information systems. However, there are few studies on business analysis competencies. The objective of this paper is to identify which competencies a business analyst (BA) needs, and analyze the importance weights and priorities of business analysis competencies. Literature review yielded 6 competency dimensions and 30 competencies. Based on interviews with 12 experts and analytic hierarchy process analysis, the relative importance weight and priority of each business analysis competency were analyzed. Moreover, an importance-perception gap between stakeholders in different positions was identified. This result can be used as selection and development criteria for superior BAs that are responsible for solving business problems using information systems solutions.

The facts of job satisfaction and their perceived importance among elementary school foodservice dietitians were assessed. The survey instrument consisted of three parts: the job satisfaction survey was used to measure facets of job satisfaction and the level of total satisfaction; perceived importance questions for corresponding job facets; and demographic items. A survey of school food service operations was undertaken and detailed information was collected from 170 dietitians. The collected data were processed using the SPSS package program for descriptive analysis and analysis of valiance. School foodservice dietitians' importance and satisfactions scores on their job and working environment were 4.25 and 2.83, respectively. The respondents rated the subscales of 'communication' and 'nature of work' the highest and the subscales of 'pay' and 'working environment' the lowest The results of facet satisfaction scores and corresponding perceived importance scores were paired to be plotted on the Importance-Performance Analysis Grid. IPA grid was used to provide a strategy for food service managers to counteract dietitian dissatisfaction.

Nowadays, every kind of system is changed so complex and enormous, it is necessary to assure system reliability, product liability and safety. Fault tree analysis(FTA) is a reliability/safety design analysis technique which starts from consideration of system failure effect, referred to as “top event”, and proceeds by determining how these can be caused by single or combined lower level failures or events. So in fault tree analysis, it is important to find the combination of events which affect system failure. Minimal cut sets(MCS) and minimal path sets(MPS) are used in this process. FTA-I computer program is developed which calculates MCS and MPS in terms of Gw-Basic computer language considering Fussell's algorithm. FTA-II computer program which analyzes importance and function cost of VE consists. of five programs as follows : (l) Structural importance of basic event, (2) Structural probability importance of basic event, (3) Structural criticality importance of basic event, (4) Cost-Failure importance of basic event, (5) VE function cost analysis for importance of basic event. In this study, a method of initiation such as failure, function and cost in FTA is suggested, and especially the priority rank which is calculated by computer-aided decision analysis program developed in this study can be used in decision making determining the most important basic event under various conditions. Also the priority rank can be available for the case which selects system component in FMEA analysis.

Purpose: This study was to investigate the belief in evidence-based practice, awareness of importance and performance of intravenous infusion and pressure ulcer evidence-based practice guidelines among nurses in a tertiary general hospital. Methods: The subjects of this study were 217 nurses working in a tertiary general hospital. Data collection was performed between February 11 and February 25, 2022. Data analysis was conducted descriptive statistics, t-test, hierarchical regression analysis, and Importance-Performance Analysis. Results: The mean score of belief for evidence-based practice among novice nurses was 3.34 out of 5, while preceptor nurses scored a mean of 3.41 out of 5. There was no significant difference in belief scores between novice nurses and preceptor nurses (t=-1.21, p=.227). The factors influencing the performance of evidence-based practice guidelines for intravenous infusion were belief in evidence-based practice (β=.14, p=.009) and importance of intravenous infusion (β=.51, p<.001), and the factors influencing the performance of evidence-based practice guidelines for pressure ulcer were belief in evidence-based practice (β=.15, p=.002) and importance of pressure ulcer (β=.65, p<.001). Importance-Performance Analysis of the evidence-based practice guidelines of two groups were used to identify common and different items. Conclusion: To improve the performance of evidence-based practice guidelines, it is necessary to enhance the evidence-based practice belief and importance of evidence-based practice guidelines. In particular, evidence-based practice should be provided to improve nursing quality through education on items of low-importance and low-performance and items of high-importance but low-performance guidelines identified through Importance-Performance Analysis.
