Nowadays, one of the main challenges facing production management is how to enhance the performance of manufacturing processes by utilizing asymmetry input and output data. This research, therefore, developed a framework for window analysis in data envelopment analysis (DEA) for evaluating the overall technical efficiencies from asymmetry dynamic input and output data. The framework was applied to assess the technical (TE), managerial (PTE), and scale (SE) efficiencies of a blowing machine under three fuzzy input variables (planned production quantity, number of defectives, and idle time) and a fuzzy output variable (actual or target production quantity). The efficiency measures were then evaluated for all DMUs at low (L), middle (M), and high (H) data levels. The obtained optimal fuzzy efficiencies were then transformed into a single crisp optimal efficiency. The results showed that all seven DMUs of the blowing machine were technically inefficient. The input and output slacks were estimated and utilized to determine the necessary improvement actions. Improvement results revealed that the optimal TE, PTE, and SE were significantly improved, which may result in significant savings in production and quality costs. In conclusion, the proposed framework is effective in improving the efficiency of the blowing process and can be utilized for efficiency assessment in a wide range of applications.

The study aims to measure the technical and intertemporal efficiency and find the primary source of productivity change on top three telecommunication firms in each country of ASEAN-5 (Indonesia, Malaysia, Thailand, Philippines, and Singapore) from 2010 to 2016. Data Envelopment Analysis (DEA) bootstrapping with 2000 iterations, DEA window, and Malmquist index are applied to calculate technical efficiency, intertemporal efficiency, and productivity change. The estimation results elucidate that, on average, the technical efficiency of firms is relatively low. On the opposite, the intertemporal efficiency results indicate that the mean efficiency score of each window is high. However, the LDW and LDP tend to be high, showing that the efficiency scores fluctuate. The Malmquist index calculation yields that technological progress possesses a significant contribution to productivity change.Keywords: Technical Efficiency, Intertemporal Efficiency, Productivity Change, Telecommunication Industry, ASEAN-5 JEL Classifications: L8, F6, O5, O1, O3

The Information and Communication Industry (ICT) plays a very important role in the growth of any nation. Therefore, the ITC sector attracts the great attention of the researcher. Despite many breakthroughs and favorable conditions to develop, the Information and Communication Industry (ICT) of Vietnam stands in a very modest position on the world’s ICT map. Therefore, understanding and having an outlook on the performance of companies in this field contribute to the development of the ICT industry in Vietnam. For this reason, the current study is conducted with the main purpose of assessing the performance of 24 Vietnamese ITC companies over past and future periods by applying a hybrid model, including Data Envelopment Analysis (DEA) and Grey model (GM). The author used GM to forecast the future value of inputs and output over period 2018–2022, and then forecasted data is used together with the data of previous years to evaluate the performance of these companies by two models of DEA—Malmquist productivity index (MPI) model and super-SBM-model. This study proposed an approach that can be used by policymakers and decision-makers to develop policies and strategies to sustain the development of the Vietnam ICT industry.

The purpose of this study was to examine the effect of total customer strategic positioning as envisaged in the Delta Model on Organizational performance. The target population consists of 6,149 front office employees of the four major telecommunication firms in Kenya namely Safaricom, Airtel, Orange and Equitel. The study covered five major cities and towns in Kenya namely Nairobi, Mombasa, Kisumu, Nakuru and Eldoret. Data was collected from 144 respondents drawn from a cross-section of employees specifically those in front office as they are directly involved in the day to day customer service. The response rate of the total questionnaires issued was 83%. A descriptive survey research design was used in this study. Questionnaires were used to collect the data. Analysis of the survey responses was done by means of Statistical Package for Social Sciences (SPSS). Pearson Correlation along with multiple regressions were used in data analysis and the testing of hypotheses. Pearson correlation was used to establish the association between the strategic position and organizational performance. The findings of the study revealed that total customer solution strategic option had a significant coefficient (=0.295, p value= 0.000). This implies that total customer solutions strategic option had a positive significant effect on organization performance. The findings of the research revealed that a change in the government regulations had a positive and very significant effect on the performance of the telecommunication companies in Kenya. This is revealed by the results which shows that there is a weak, positive correlation which is significant (R = 0.358; p-value <0.05) government regulations and organizational performance of telecommunication firms in Kenya. The study concluded that the total customer solution strategic positioning had not only a positive correlation but also significant effect on the organizational performance of the telecommunication companies in Kenya. The study also concluded that with appropriate government regulations the strategic positions studied will enhance organizational performance in the telecommunication industry in Kenya. The study recommends that managers need to focus on the use total customer strategic position in order to achieve a great organizational performance in their respective organizations.

This study benchmarks the cross-layer productivity of information and communications technologies (ICT) for the period between 1996 and 2015. Our results display that layer 3 companies (platforms, e-commerce, content and software) are the drivers of productivity growth within the ICT industry in the recent years. In contrast, layer 2 companies (network operators) score lower in efficiency than the other layers and experience a continuous decline in average productivity since mid-2000s. We note that, the key financial performance indicators signal a slowdown in the ICT industry since 2011, after when average increase rates of revenues and total assets dropped significantly. The stagnation is severer for network operators, which have been the main investors of the networks on which ICT rises.
