Organizations specifically the airlines industry are increasingly facing the challenges of operational efficiency measurement. During the last years enormous attention has been given to the assessment and improvement of the performance of productive systems. However, literatures show that there are limitations of the existing models to measure efficiency uniformly and exhaustively across the airlines. The problems are due to lack of the technical efficiency measuring model which unifies and integrates different measuring models into a single model.Therefore, this thesis investigates assessment of the operational performance of world major airlines by employing integrated comparative models to address the above problems. In this study, technical efficiency is addressed among many performance issues by using three types of modes of performance measurement: a non parametric one, represented by Data Envelopment Analysis (DEA) and; a parametric one, represented by Stochastic Frontier Analysis (SFA) and the Balance Scorecard (BSC) which is a strategic management tools. Unlike most of the previous studies, this study integrates the BSC concepts into DEA and SFA model. To evaluate technical efficiency of major international airlines, the study use panel of unbalanced data for the year 2007-2014 to make integrated comparative analysis. The research project incorporates seven leading variables and four lagging variables taken from BSC concept to implement into the DEA and SFA. All the three models of performance measurements have their own strength and limitation if they are used alone. But if the three models are integrated and combined together, they would yield better comparative and quality of efficiency assessment. Therefore, the study primarily developed a model beginning from the theoretical framework assumption into building of a unified comparative model of integrated comparative operational efficiency assessment of airlines. The research design and methodology uses secondary data collection i.e. annual reports and business reports of airlines which are collected from the airlines own website. The huge amount of financial and operational data cannot be collected by using primary data collection method as it would make it practically impossible and expensive. So by employing secondary data collection method saves time, money and a panel data can be accessed and generated easily. Hence, from 100 world major airlines population which are ranked by revenue, simple random sampling is used to select 80 samples airlines for this study. First, the BSC identifies the input and output variables. Next, the DEA model ranks the efficiency measurement, identifies the slack variables and benchmarks the airlines. Third, the SFA model identifies technical efficiency, the random error and technical inefficiency. Finally, the technical efficiency estimates obtained from the two techniques are analyzed comparatively. The research makes further analysis of particular case of the Ethiopian Airlines in relation to the most efficient and inefficient airlines and in comparison of the regional analysis. After extensive tests have been conducted, ‘Balanced Frontier Envelopment’ model is developed. According to this model, it is a paramount to measure efficiency with combining the strength of three models together and gives better results than the previous one or two combined models. The developed and integrated strategic model enhances measuring of the operating technical efficiency of airlines. This model benefit the airlines industry in many ways such as minimizing the cost and maximizing profit through managing technical efficiency which lead into the success of the airlines. From the model perspective, therefore, result of DEA model is much higher than the result of SFA model. DEA model is easier to manipulate than the SFA model because the former does not need the functional form while the later requires a functional form. Furthermore, according to the efficiency finding of the study, first, the European regional airlines are relatively more efficient than the rest of regions in the world. Second, the North America regional airlines are the second more efficient regional airlines in the world. Third, the Ethiopian airlines are the most efficient in Africa when we compare among Egyptair, Kenyan Airways and South African Airways. Fourth, high revenue does not necessarily leads to the technical efficiency of the firm. / Business Management / D.B.L. (Business Leadership)

To date there is little evidence on the effect of property-liability (P-L) insurer's business strategy and organizational structure change on their frontier efficiency performance and productivity change. This issue is important since traditional theory assumes firms that minimizes cost and maximizes profit with more efficient strategy will survive in the long run. The main goal of this dissertation is to examine the efficiency performance in the U.S. P-L insurance industry using frontier efficiency and productivity methods. This dissertation consists of three essays on the efficiency studies. The first essay uses the data envelopment analysis to examine the efficiency performance and economies of scope for nonspecialists and specialists in the U.S. P-L insurance industry. The empirical evidence suggests that nonspecialists (specialists) dominate specialists (nonspecialists) in producing nonspecialists (specialists) input–output vectors and provide evidence for the coexistence of economies of scope and diseconomies of scope in the U.S. P-L insurance industry. Our second essay uses the stochastic frontier analysis to examine whether nonspecialized strategy dominates specialized strategy in the U.S. P-L insurance industry. The empirical evidence supports that both the nonspecialized hypothesis and the specialized hypothesis hold for different types of P-L insurers. Our third essay investigates whether the conversion of U.S. P-L insurers improves their efficiency performance before and after conversion. The empirical evidences of the value-added approach and the financial intermediary approach indicate that converting insurers experience improvement in their efficiency relative to mutual counter samples after the conversion, supporting the efficiency hypothesis proposed by Mayers and Smith (1986). Overall, the evidence of this dissertation shows that P-L insurer's diversification strategy and organizational structure change has significant impact on their frontier efficiency performance and productivity change.

經濟時代，智慧資本係企業創造競爭優勢及永續經營之核心關鍵，基於有效管理智慧資本，對其進行衡量之應用需求日漸殷切。本研究嘗試利用資料包絡分析法整合系統理論「投入—轉化—產出」之觀念，將智慧資本衡量指標區分為投入與產出項目，建構企業智慧資本轉換能力，並藉複迴歸分析，探討其對企業績效之影響；此外，與另外一項評估工具—智慧資本增值係數比較，探討何者對於企業績效具有相對較高之解釋能力。研究對象為我國2005年至2007年92家資訊電子業上市公司之縱橫資料。 實證結果發現，智慧資本轉換能力對市價淨值比未達顯著影響，顯示目前大部分投資人進行投資決策時較關注反映企業營運結果之財務產出面向，而不注重過程面資源投入產出間之成本效益分析；智慧資本轉換能力與資產週轉率呈正向相關並達顯著水準，亦即轉換能力越高，企業運用資源的效率越好；而在Vuong test檢測下，智慧資本轉換能力對企業績效解釋能力並未顯著優於智慧資本增值係數。本研究結果顯示，智慧資本轉換能力確實可提供一具體衡量企業智慧資本之指標，作為企業資源配置決策之有用資訊以提升企業經營績效。 / Intellectual capital(IC) is vital to achieving sustainable competitive advantage in the knowledge-based economy. In attempting to effectively managing IC, demands for IC measurement and application are increasing. This study integrates the system theory with Data Envelopment Analysis (DEA) to measure a firm’s intellectual capital transform capability (ICTC). The main purpose of this study is to examine the association between ICTC and corporate performance. Moreover, the study also compares the relative explanatory ability about business performance between ICTC and Value Added Intellectual Coefficient (VAICTM). Samples are drawn from 92 listed firms in Taiwan information and electronics industry, covering a 3-year panel data from 2005 to 2007. The result indicates ICTC has a significant positive impact on asset turnover ratio, which suggests that ICTC can be an indicator to measure a firm's operating capability. However, ICTC is unrelated to market-to-book ratio, which shows that ICTC explains business operating performance better than market performance. The Vuong test reveals that in explaining the performance of a business VAICTM does not have a higher explanatory ability than ICTC. This finding implies that ICTC can provide a valuable indicator for measuring IC, help a firm to efficiently allocate its resource and improve a firm's operating performance.

地方稅捐稽徵機關績效之良窳攸關地方政府庫收，更直接影響地方經濟成長、資源配置效率與所得分配之公平；本文試圖採用能排除外在因素與隨機干擾之三階段產出導向資料包絡分析法（以下簡稱DEA），針對23個地方稅捐稽徵機關2004年迄2008年資料進行管理效率評估，再以隨機邊界分析法（以下簡稱SFA）分離外生因素及隨機干擾以調整各機關產出至相同基準後，再評估排除外在與隨機干擾因素的管理效率。 未考慮外生因素與隨機干擾的DEA效率評估結果顯示，有高達88.7%及82.6%的地方稅捐稽徵機關分別於技術效率及純技術效率上尚有改善空間。第二階段SFA估計結果顯示，土地移轉現值、機關內大專畢業以上員額之比例及員額平均年齡對管理效率皆有正向影響；而總統大選期間及有高鐵停靠站之縣市除對部分產出無顯著影響外，對管理效率之提升亦具優勢；然而，服務轄區土地面積與實徵淨額之效率呈負相關，卻與違章漏稅裁罰效率呈正相關；地方首長選舉期間除為避免清理欠稅招致民怨而降低技術效率外，對其他管理效率則皆呈正相關；又都市計畫面積占稽徵區域比例與地方稅實徵淨額之管理效率呈正相關，卻與欠稅清理效率呈負相關。調整後之DEA結果顯示各項效率值與調整前比較皆存在顯著差異，顯示排除外生因素與隨機干擾影響以避免效率值被錯估確有其必要性；但仍有高達93.05%及68.7%之地方稅捐稽徵機關分別於技術效率及純技術效率上存有改善空間；又多數稽徵機關處於規模報酬遞增階段，即產能過剩而造成資源浪費。另與財政部稽徵業務考核成績比較分析，在規模效率平均值排名方面，除臺南市外，甲組機關排名普遍優於乙組機關；但純技術平均效率值之排名卻有一半以上之甲組機關表現反而不如部分乙組受評單位；顯示甲、乙組之分類歷經多年仍沿襲舊有分組將使各機關未能於適合之群組中受考而錯估其績效。 基於上述實證研究結果，本文提出下列政策性建議： 一、建議逐期分階段調整人力及預算至最適規模，以善加運用資源降低產能過剩情形。 二、建議各機關應引用環保之共乘概念，加強政府機關間橫向溝通、聯繫與合作。 三、若情況允許，建議可不區分甲乙組針對全體地方稅捐稽徵機關進行考核。若人力、時間或其他情況不允許，建議研擬具體方案隨各機關規模改變而有重新分級之機制。 四、建議甲組機關亦可選擇純技術效率較佳之乙組機關作為觀摩學習之對象。 五、建議財政當局可考慮將外在因素之影響納入評核，以提升考核之信度與效度。 最後，臺灣自2010年底起將有部分縣市改制為直轄市，考核編組方式勢將有所變革，有待後續研究者追蹤探討；而改制後所引起之資源重分配亦可作為未來之研究議題。 / The Performance of Local Tax Bureaus is relevant to the revenue of Public Treasury, and even has direct impacts on local economic growth, efficiency of resource allocation and equity of income distribution. This paper attempts to use three-stage out-oriented DEA which can rule out the external factors and the statistical noises to evaluate the efficiency of 23 Local Tax Bureaus in Taiwan during the period of 2004 to 2008. After measuring slack variables of each Bureau in the first stage, the Stochastic Frontier Analysis (SFA) model is used to separate the external factors from the statistical noises, and then adjust the output of each Bureau to the same benchmark. Finally, DEA is again used to evaluate the efficiency of 23 Local Tax Bureaus. The DEA efficiency evaluation results in the first stage show that up to 88.7% and 82.6% of the Local Tax Bureaus still have an ample room to improve their technical and pure technical efficiency. In the second stage, the SFA model estimates show that “the present value of land transfer”, “the proportion of post-graduates in the Bureaus” and “the average age of the staff” have positive effects on the efficiency. “The period of Presidential Election” and “the cities or counties that Taiwan High Speed Rail have set station up” have insignificant impact on part of the outputs, but still have the advantages to enhance the efficiency. However, “the expanse of land in service area” has a negative correlation with the efficiency of net taxation, but is positively related to the efficiency with the fine of illegal tax evasion. “The election period of Local County Executive” has a positive correlation with the efficiency except that tax arrears liquidation might reduce technical efficiency. “The ratio of urban-planed area to the tax levy regional” and the efficiency of net taxation are positively correlated, but negatively related to the efficiency of tax arrears liquidation. After excluding external factors and the statistical noises, the third-stage DEA evaluation results are significantly different from those in the first stage, indicating that it is necessary to exclude impacts of external factors and statistical noises in order to avoid the misjudged value of efficiency. There are still as high as 93.05 % and 68.7% of the Local Tax Bureaus have an ample space for improvement respectively on technical efficiency and pure technical efficiency. Most of the Tax Bureaus are at the increasing return of scale stage, implying that the surplus of capacity cause the waste of resources. Finally, compared with the performance evaluation held by Ministry of Finance, the empirical results in this study show that although the classification of Local Tax Bureaus has been adopt for many years, Bureaus’ performance evaluation results might be misjudged in the unsuitable group. Based on the above empirical results, this research attempts to propose the following policy suggestions: 1. It is recommended to adjust the phase of manpower and budget to the optimum scale for the best using of resources and to reduce inefficiency of excess capacity. 2. Enhancing horizontal communication among government agencies may improve the efficiency of Local Tax Bureaus. 3. If possible, it is recommended to evaluate Local Tax Bureaus without classification. If not, a mechanism of re-rating according to the scale change of Local Tax Bureaus may be needed. 4. It is proposed that Local Tax Bureaus of Group A can take lesson from those of Group B with better pure technical efficiency to learn from. 5. It is suggested that government authorities have to exclude the effect of external factors to improve the reliability and validity of performance evaluation. At the end of year 2010, several counties will be restructured in municipalities. The classification of Local Tax Bureaus for performance assessment must be changed. The reallocation of resources caused by restructuring may be used in future studies.

關於供應商評選模式的探討與研究，是現今於供應鏈管理中非常重要的議題，而對於國內外供應商評選的相關性研究中，往往只考量供應商本身績效，而缺乏整體性的考量，有鑑於此，當企業在評選供應商時，不僅是針對單一供應商績效的考量，而對於供應商本身上下游廠商的整體績效的考量，也是相當重要的評選因素。本研究運用資料包絡分析法(Data Envelopment Analysis, DEA)與簡易多屬性評等技術(Simple Multi-Attribute Rating, SMART)，以建構較完整的供應商評選模式，協助企業的決策者選擇最適的供應商。 在進行供應商與供應商所屬的供應鏈之績效評估時，利用資料包絡分析法中的交叉模式計算供應商與供應商所屬的供應鏈之平均效率，再藉由平均效率值以排序供應商與供應商所屬的供應鏈之優先順位，但因兩者之順序會產生不一致的情形，利用SMART法中的排序加總法計算兩者之權重值，最後以加總法計算綜合效率值，依據綜合效率值加以排序以評選最適的供應商，而此兩種方法的結合， 則需透過驗證的方式以確定運用之正確性，利用系統動力學(System Dynamics, SD)以建構供應鏈之整體廠商的經營環境，模擬供應鏈整體廠商之績效評估模式，以產生模擬驗證排序，最後再將綜合排序與驗證排序，利用Spearman等級相關係數驗證其相關性，而最終證明兩排序具有高度相關性，也證實本研究所提出的供應商評選模式富有參考價值。 / The research of supplier selection model is a very important issue in supply chain management (SCM). Even though the research on supplier selection is abundant, the most works usually only consider the performance of the supplier. This situation can result in a lack of integral deliberation. Therefore, the decision-maker wants to select his vendor in the company, it is important that the decision-maker not only focus on the business unit but also add to the overall organization of the supply chain. In this paper the Data Envelopment Analysis (DEA) and the Simple Multi-Attribute Rating (SMART) are developed to construct the effective supplier evaluation model depends upon the constituent parts of the supply chain, which may be helpful for selecting the appropriate vendor. When evaluating the performance of the supplier and the supplier’s supply chain, the cross-efficiency model of DEA is applied to compute average efficiency both the supplier and the supply chain. According to average efficiency, we can arrange the priority order that may be have the inconsistent order for the suppliers and their supply chains. The rank sum weighting of SMART is employed to determine the weights of suppliers and their chains and then the weighted method is used to calculate overall efficiency that ranking of the suppliers is obtained. Above of two methods, we must be verify the model. The System Dynamics (SD) is designed to implement the whole components of the supply chain for business environment and simulate the performance model. Based on this performance model, we can acquire a confirmation list. In the end, the Spearman’s rank correlation coefficient is provided to testify the correlation between the overall order and the confirmation list. The result of the statistic analysis is illustrated the strength of the association. The model can be tailored and applied by firms that are making decisions on supplier selection.

我國國立高級中等學校實施校務基金之目的除了提升績效外，尚期以增進各校自籌財源之動力，以減輕政府財政負擔，自2007年起開始實施校務基金後之績效為何?值得進一步探討。 本研究係以資料包絡分析法評估各國立高級中等學校2010年至2012年的經營績效，並運用麥氏指數衡量其跨期效率變動情形，最後以Tobit迴歸分析，探討外在環境變數對校務基金實施績效之影響。實證研究結果如下： 一、總技術效率分析：2010、2011及2012年平均總技術效率值依序為0.712、0.714、0.705，表示各該年度尚有28.8%、28.6%及29.5%的效率改善空間。若將各國立高級中等學校依照類別區分，普通高中平均總技術效率表現最佳，綜合高中的表現比職業學校佳，特教學校最差。 二、純技術效率分析：2010、2011及2012年平均純技術效率值依序為0.768、0.781、0.771，表示各該年度尚有23.2%、21.9%及22.9%的效率改善空間。普通高中平均純效率表現最佳，綜合高中的表現比職業學校佳，特教學校最差。 三、規模效率分析：2010、2011及2012年平均規模效率值依序為0.923、 0.908、0.908，表示各該年度尚有7.7%、9.2%及9.2%的效率改善空間。2010年以職業學校表現最佳，2011年以綜合高中表現最佳，2012年度以普通高中表現最佳。特教學校在三個年度的平均規模效率均為最差。 四、麥氏指數分析：2010至2012年度之總要素生產力變動值均小於1，呈現衰退現象， 2010至2011年度及2011至2012年度二個跨期均呈現衰退。 五、Tobit迴歸分析：除實施校務基金的年限無顯著影響外，學校區位、校舍面積及學校成立年限等三項外在環境對學校的經營績效均具有影響。 / The purpose of national senior high schools in Taiwan implementing National Senior High Schools Operation Fund is not only improving performance, but also enhancing the schools’ self-motivation of the financial resources to reduce the fiscal burden of government. How is the performance of implementing National Senior High Schools Operation Fund since 2007?It is worthy of further study. This study is based on Data Envelopment Analysis to evaluate the operating performance of national senior high schools from 2010 to 2012. In addition, this study uses Malmquist Index to measure the efficiency changes. Finally, Tobit regression analysis is used and tried to find effects of the external environment variables on the implemenetation performance of National Senior High Schools Operation Fund. The findings of this study are as follows: 1.Overall technical efficiency analysis：the average value of the overall technical efficiency is 0.712、0.714、0.705 in sequence of year 2010、2011 and 2012, and it means that the efficiency improvement is 28.8%, 28.6% and 29.5% each year. If we evaluate the performance of national senior high schools by category, the general high schools are the best, the comprehensive high schools are better than vocational high schools, and the special education schools are the worst. 2.Pure technical efficiency analysis.：the average value of the pure technical efficiency is 0.768、0.781、0.771 in sequence of year 2010、2011 and 2012, and it means that the efficiency improvement is 23.2%、21.9% and 22.9% each year. The general senior high schools are the best, the comprehensive senior high schools are better than vocational senior high schools, and the special education schools are the worst. 3.Scale efficiency analysis: the average value of the scale efficiency is 0.923、 0.908、0.908 in sequence of year 2010、2011 and 2012,and it means that the efficiency improvement is 7.7%、9.2% and 9.2% each year. The best performance is the vocational senior high schools in 2010, the comprehensive senior high schools in 2011, and the general senior high schools in 2012, the special education schools are the worst in all three years. 4.Malmquist Index analysis: the value of the total factor productivity change is totally less than 1 from 2010 to 2012, and shows the recession .And the inter-temporal total factor productivity changes show the recession from 2010 to 2011, and 2011 to 2012. 5.Tobit regression analysis: there is no significant impact in the factor of the years of the National Senior High Schools Operation Fund, but the external factors such as the size, the history, and the location of the schools, would affect the performance of national senior high schools.

本研究欲探討兩岸銀行業公司治理與經營績效之關聯性，使用資料包絡分析法及交叉效率分析比較2008至2013年兩岸銀行業的經營績效。根據本研究實證結果顯示：兩岸銀行業確實分屬不同效率前緣，且中國銀行業業之技術效率優於台灣銀行業之技術效率。但金融海嘯後台灣在規模效率上進步，顯著超過中國。在公司治理機制與經營績效關聯性分析中，顯示兩岸因制度性的差異上，使得公司治理變數與經營績效之關聯性幾乎完全相反。在政府持股率與經營績效關聯性上，雖然都不顯著，但中國係數為正，台灣為負，說明兩岸政府對企業的影響力是有所差異。獨立董事比例與純粹技術效率是唯一兩岸都顯著之變數，但中國為顯著負相關而台灣為顯著正相關。研究結果顯示兩岸在公司治理實務與經營績效有很大的差異。 / The purpose of this paper tries to make a cross strait comparison between corporate governance and efficiency performance in banking industry. We apply data envelopment analysis and cross efficiency frontier analysis to measure and compare the performance of banking industry between Taiwan and China from 2008 to 2013. The empirical results reveal that Taiwan and China indeed have different efficiency frontier, and the cross frontier analysis suggests that the efficiency performance of China is much better than that of Taiwan. However, the scale efficiency of Taiwan had a better performance than that of China after financial crisis. Due to system difference, the cross strait comparison of corporate governance between efficiency performances denotes that Taiwan and China almost have opposite effects. China indicates a positive coefficient between bank’s stock holding ratio by government and efficiency performances. On the other hand, Taiwan indicates a negative coefficient, although both are statistically insignificant. The result suggests that the political power has a contrary influence for Taiwan and China. The percentage of independent directors is the only variable that statistically significant with pure technical efficient on both sides. However, which is negative coefficient associated with China, but positive coefficient associated with Taiwan. Therefore, we can conclude that the corporate governance practices have opposite influence on efficiency performance between Taiwan and China.

The greater competition and concentration in South Africa's financial sector has put South African banks under more constraints and led to questioning of their present performance. With a greater demand for financial services and more complains about the low quality of financial services and charges being too high, there has been increasing debate about how efficient South African banks really are. This study discusses performance evaluation, the traditional financial and non-financial measures used, and their limitations. The concept of bank efficiency is also briefly discussed, including scale efficiency, scope efficiency, X-efficiency, cost efficiency, standard profit efficiency, alternative profit efficiency and the risk component of bank efficiency. Data Envelopment Analysis (DEA) was chosen as the most appropriate method to estimate the scale efficiency and technical efficiency of 37 districts (and 10 provinces) of one of the largest banks in South Africa. 'DEA involves solving linear programming problems that generate a non-parametric, piecewise linear convex frontier that envelops the input and output data relative to which cost is minimized' (Fare et al., 1985b:193). The intermediation approach was used incorporating both the input- and output-orientated approach under variable returns to scale. The analyses indicated that 19 districts out of the 37 districts were not at least once fully technically efficient during the 22 months (input- and output-orientated). The same results were found with regard to scale efficiency: 17 districts out of the 37 districts were not at least once fully scale efficient (input-orientated) and 19 districts out of the 37 districts were not at least once fully scale efficient (output-orientated), during the 22 months. Synergy was found in 6 provinces out of the 10 provinces (input- and output-orientated). / Thesis (M.Com. (Risk Management))--North-West University, Potchefstroom Campus, 2008.

本研究透過個案研究，運用資料包絡分析法(DEA)的評估方式，分析製藥業在不同生命週期及通路上資源分配之行銷策略與銷售績效之關聯性。研究結果發現： 一、不同生命週期「成長期」、「成熟期」及「衰退期」產品，其整體銷售技術效率、純銷售技術效率與銷售規模效率之差異，均達統計上之顯著水準。「成長期」產品效率值最差、「成熟期」產品效率值次之、「衰退期」產品效率值最佳。 二、不同生命週期產品在主要銷售通路醫學中心、醫院、診所與藥房的銷售比重不同。「成長期」與「成熟期」產品的主要銷售通路均在醫學中心，而「衰退期」產品的主要銷售通路在藥房。其銷售績效差異在醫學中心與藥房通路，衰退期產品與成熟期、或成長期產品比較，均達到統計上之顯著差異水準，但在醫院與診所通路的銷售績效，三類產品族群的差異就不明顯。 三、個案藥廠對其主要銷售的藥品，雖然都有非常明確的個別產品銷售策略與目標，但差額變數分析結果顯示，仍有部份產品在資源分配及運用上，可以加以改善以提高銷售績效。 / This research is conducted using Data Envelope Analysis (DEA) assessment method to analyze the particular pharmaceutical company on the association between marketing strategy and sales performance with different life-cycle products and sales channels. The results are as follows: 1.Sales performance appears significant differences among different life-cycle products with respect to the overall technical efficiency、pure technical efficiency and scale efficiency. The results revealed that products in「Growth Stage」had the worst efficiency performances, 「Maturity Stage」products placed the second, and「Decline Stage」products were the best. 2.Sales weight differs from different life-cycle products in the major sales channels of medical centers, hospitals, general practitioners and drug stores. The main sales channel of「Growth Stage」and「Maturity Stage」products are in medical centers；while「Decline Stage」products are in drug stores. Statistics showed that the sales performance differed substantially when the three different life-cycle products were distributed to sell in medical centers and drug stores; however, the results were not as evident in hospitals and general practitioners channels. 3.Although the case pharmaceutical company has very clear sales strategies and goals for its individual products, the analytical results showed some changes could be made to improve sales performance.
