The Impact

This study offers empirical findings on the impact of institutional variables on firm’s stock market price performance. In order to identify the influence of companies financial on NIFTY 50 Index, our sample consists of balanced panel of 30 actively traded companies (that becomes the study’s index representative) over a massive transition period, 1995–2014. Attempts have been made with a wide range of econometric models and estimators, from the relatively straightforward to (static) more complex (dynamic panel analyses) to deal with the relevant econometric issues. Results indicate that increasing debt in capital structure does not establish any significant relation with the stock prices. Earnings per share (EPS) shows a poor explanation of price variation. Economic value added (EVA) indicates a positive relation with current as well as previous year’s stock price performances. However, dividend payout (DIVP) and dividend per share (DPS) achieve negative relationship at moderately significant level. The present study confirms that performance of companies fundamental ratios will be essential and immensely helpful to investors and analysts in assessing the better stocks that belong to different industry groups.

The Impact

The provision of and access to financial services, particularly credit, can contribute greatly to the development of microenterprises in South Africa. Such provision has been an issue ignored by conventional banks or formal financial institutions. The problem associated with this ignorance includes high transaction and operation costs, lack of collateral, and the inability to obtain information about microenterprises resulting in difficulties to extend such credit. Microfinance therefore becomes an alternative to conventional banking and a mainstream and sustainable development activity for extending credit to microenterprises. However, the benefits of microfinance, which include, among others, the ability to provide the much-needed financial support for microenterprises, have not been fully harnessed in South Africa. The objective of this article is to evaluate the impact of microfinance on microenterprises in a typical South African township and to propose specialized financial mechanisms to support and improve the provision of credit to microenterprises. The article draws on the findings of a study undertaken in the Ga-Rankuwa township located in the Tshwane Metropolitan area in the Gauteng province of South Africa. It further draws on a wide range of extensive review of literature that documents the impact of microfinance on microenterprises. A case study approach is adopted and mixed method research paradigm (qualitative and quantitative) is used to gather information. Structured questionnaires and interviews were used to solicit information from the randomly selected microfinance institutions and microenterprises in the Ga-Rankuwa township.

PT PLB (pseudonym) is a company that produces household appliances and kitchen utensils. The country kettle is one type of product made by PT PLB. The productivity of the country kettle production line decreased by 56%. This was due to defective products. The largest percentage of defects in-country kettle products occurred in the spinning process of 40.18%. This study aimed to identify the causes of defects in-country kettle products and how to overcome them by designing improvement proposals. Lean manufacturing principles were used to evaluate the problems that occur. There were three types of lean manufacturing tools used in this study: Value Stream Mapping (VSM) and 5Ways. VSM was used to describe and identify value-added activities, non-value-added activities but necessary, and non-value-added activities so that the production process becomes lean. The root cause analysis was performed using the 5 Whys method. Unskilled workers and non-standard material types between suppliers are the highest contributors to defects in the spinning process. Based on this, this research was focused on improvements made in the spinning process. Proposals for improvements to the causes of the problems found are standardization of work procedures, standardization of supplier specifications, and arrangement of semi-finished goods and/or supplies. Based on the company's results, the proposed standardization of work procedures and arrangement of semi-finished goods and/or supplies may be implemented in the company. Meanwhile, the proposal for selecting suppliers is not feasible due to company limitations

Engine maintenance strives to always improve its service excellence with tools such as gate system where the system is expected to realize the lead time for 60days. In the implementation of the gate system is still not able to meet the expected target. During maintenance or overhaul the engine is still encountered waste or waste that causes the target cannot be met. Lean Manufacturing is an approach that aims to minimize waste that occurs in the process flow.Understanding the conditions of the process described in Value Stream Mapping for further elaborate activities that have the value-added and non-value added.Through seven waste concept, then be weighted to determine the most dominant type of waste.From the data processing is obtained that through the Value Stream Mapping is known gate 1 and gate 3 is the point that there are many wastes. Weighting and ranking of seven existing waste in the process of the activity obtained results in the form of a waste critical sequence of seven existing waste. Highest weights on the type of waste waiting with a weight of 0.38. Results of Root Cause Analysis in mind that the root cause of waste waiting for that data is maintained, the lack of attention to people development, There are still bugs in the system and miscommunication.

Manufacturing Applications

In recent times, lean manufacturing applications have become essential for manufacturers all over the globe. The manufacturers have gradually shifted from mass production to flexible manufacturing and customers are looking for customized and unique products. Productivity becomes a very important element with multiple product need. Passenger vehicle seat manufacturing industry is found to be poorly affected by manufacturing problems due to more cycle time, unbalanced workload and improper layout. The main aim of this paper is to study the existing system of a seat manufacturing industry and to improve productivity using lean methodology without much affecting current working systems. The critical non value added activities are identified and chances required for improvement has been recognized. The total lead time was reduced from 2.55 days to 2.438 days after implementation of applications of VSM. Using spaghetti diagram the current layout was optimized and the total cycle time was reduced by about 26.28% after implementing the proposed layout to meet the customer demand.

The Impact

Due to globalization, the world has become smaller and smaller with highly intense business competition. Thus, any organization, places more emphasis on looking for ways to survive based on reducing overall costs without decreasing product quality. Hence, identifying inefficient activities are becoming a core way to help manufactures decreasing in the operating costs while gaining a competitive advantage. However, few studies are concerned about searching for root causes of problems that are main obstacles for production improvement. Therefore, the purpose of this study is to explore on the impact of production performance and find a root cause for non-value-added activities through lean production and other quality tools application in a set of companies via a case study of SMEs. In short, bottleneck areas were identified for each company, and the problems were removed through increasing the processing time at those areas. The findings shows that motion and process wastes, compared to other wastes, are the main impacts for obstacles in production performance caused by poor workplace organization and lack of standardized work. The biggest barrier to lean production implementation is decentralization and changing the culture of workers, which requires the agreement of the top manager and involves of everyone in the entire SMEs.

The Impact

While Design for Assembly (DFA) has been a useful design tool, it is not explicitly linked to actual manufacturing line performance. The motivation for this research came from the desire to link DFA directly to line balance and cycle time performance. The natural question that arose was whether these issues could be considered at the design stage by using the metrics that are derived from a DFA analysis. It is known that the time required to assemble a product can be estimated from both a DFA analysis and from a manufacturing analysis. This work links these two analysis methods so that the manufacturing parameters can be estimated and used to guide the design of a product. Starting with a DFA analysis, the minimum number of workstations needed to balance the line that will maintain the production rate (takt time) and precedence constraints is determined. Then the precedence constraints are systematically relaxed in order to generate measures on a component-by-component basis as to the impact it could have on reducing cycle time and improving line balancing performance. These measures, coupled with an understanding of precedence types, are used to identify design improvements to a product. To illustrate how product designer can consider assembly line performance issues during the design stage of the product, the methodology has been applied to an ABS brake assembly.
