A large number of empirical studies have been conducted examining the impact of strategic planning on organisational performance. Many studies have suggested that this relationship is influenced by various factors like the type of industry, environment, CEO characteristics and organisational systems. However researchers have not been able to provide conclusive evidence about the effectiveness of strategic planning to enhance performance. In order to examine the current state of the literature and to summarise the findings from various empirical studies, a comprehensive literature review has been conducted by reviewing sixty eight papers published in leading academic journals. The framework followed by Podsakoff and Dalton (1987) was adapted to conduct the literature review. 1 Assistant Professor, Indian Institute of Management Kozhikode, IIMK Campus 2014-01-01T00:00:00Z http://dspace.iimk.ac.in:80/xmlui/handle/2259/721 A Phase-II Nonparametric Cusum Chart with an Application to Exchange Rates Data Mukherjee, A; Marozzi, M; Chowdhury, Shovan Recently, Chowdhury et al. (2014a) proposed a single distribution-free Shewhart-type control chart based on the Cucconi (1968) test statistic for monitoring shift in the unknown location and scale parameters of a process distribution simultaneously. Several recent researches demonstrated that the CUSUM type charts perform better than the Shewhart-type charts under small and persistent shift. In the present work, we develop a phase II distribution-free CUSUM chart based on the Cucconi statistic, referred to as CUSUM-Cucconi (CC) chart. Nonparametric nature of the Cucconi statistic ensures that all the in control (IC) properties of the proposed chart remain invariant and known for all continuous process distributions. Control limits are tabulated for implementation of the chart. The IC and out of control (OOC) performance of the chart are thoroughly investigated in terms of the average, standard deviation, median and some percentiles of the corresponding run length distributions. A detailed comparison with the Shewhart-type Cucconi and Lepage charts as well as the CUSUM Lepage chart (as in Chowdhury et al. (2014b)) is presented. The proposed chart is illustrated with exchange rates data. 1 Indian Institute of Management Udaipur 2 Dipartimento di Economia e Statistica, Università della Calabria, Rende (CS), Italy 3 Indian Institute of Management Kozhikode, IIMK Campus 2014-11-01T00:00:00Z http://dspace.iimk.ac.in:80/xmlui/handle/2259/720 Stochastic Comparisons of Parallel Systems of Heterogeneous Generalized Exponential Components Kundu, Amarjit; Chowdhury, Shovan; Nanda, Asok K Let X1;X2; : : : ;Xn (resp. Y1; Y2; : : : ; Yn) be independent random variables such that Xi (resp. Yi) follows generalized exponential distribution with shape parameter i and scale parameter i (resp. i), i = 1; 2; : : : ; n. Here it is shown that if = ( 1; 2; : : : ; n) majorizes = ( 1; 2; : : : ; n) then Xn:n will be greater than Yn:n in reversed hazard rate ordering. That no relation exists between Xn:n and Yn:n, under same condition, in terms of likelihood ratio ordering has also been shown. It is also shown that, if Yi follows generalized exponential distribution with parameters ; i, where is the mean of all i's, i = 1 : : : n, then Xn:n is greater than Yn:n in likelihood ratio ordering. In this context, an error in Marshall, Olkin and Arnold [Inequalities: Theory of Majorization and Its applications (2011)] has been corrected, and some new results on majorization have been developed. 1 Department of Mathematics Santipur College, West Bengal, India 2 Indian Institute of Management Kozhikode, IIMK Campus 3 Indian Institute of Science and Educational Research, Calcutta 2014-10-01T00:00:00Z http://dspace.iimk.ac.in:80/xmlui/handle/2259/719 Lean Thinking in Healthcare Sector: Experience from an Indian Hospital Narayanamurthy, Gopalakrishnan; Gurumurthy, Anand Experience of implementing lean thinking (LT) in a multispecialty hospital located in southern part of India is discussed. Case hospital was chosen and problems associated with various processes were identified and they were mapped to seven wastes. Solutions based on lean principles/practices were implemented and improvements were evaluated through performance measures. 1 Fellow Program in Management, Quantitative Methods & Operations Management Area, Indian Institute of Management Kozhikode (IIMK), Kerala, India 2 Associate Professor, Quantitative Methods & Operations Management Area, Indian Institute of Management Kozhikode, Kerala, India. 2014-01-01T00:00:00Z
