Individual operations management report - Essay Example Lately, the company has been facing tough competition from Chinese manufacturers impacting both its top line and bottom line. In order to improve the situation, the company has initiated a quality improvement plan. Statistical Process Control is being used at one of its toy plants as one of the tools for enabling Total Quality Management. Under this initiative the company plans to analyze the quality of a doll manufacturing unit due to growing concerns over increasing customer returns. The company has decided to evaluate two important parameters of quality – colouring and height of the dolls. The data has been collected over a 30 day period. Statistical Control charts are of various types and are used depending upon the situation and the nature of data recorded. For the first set of data, that is, the data for colour defects, c-chart would be the most appropriate control chart since c-chart is used for the number of defects. Since, the number of units tested is constant (=200) in each sample, c-chart is perfect for the situation. Else, a p-chart could have been used. The values of constants A2, D3 and D4 are taken from standard tables for control chart constants (Here values for n=25 have been assumed for the sample size of 30 as the tables contain values till n=25 and calculating annually for higher values is very cumbersome) (Table for Control Chart Constants). For the colour defects, only 1 value (14) is found to lie outside the two control limits. Hence, from the colour defects point of view, the process is only marginally out of control. The control chart for the same is shown in Figure 1. For the heights, a large number of values in both R chart and x bar chart are found lie outside the control limits. Thus, this is a major concern area for the company. The two control charts for the same are shown in the Figures 2 and 3. Tom Pulling Toys needs to pay some attention to

Application implement into a business - Essay Example Wrapped wire method also is said to have a digital use of circuit for using solder less boards. Advantages of wrapped wire are as follows, it is reliable method, it is relatively cheap, can be used to make a permanent circuit, the last but not the least it is fast and easily to change the system for better operation. Although, this method is highly preferred in most of machines which consume relatively high voltage, they are associated with demerits such that connection to the lead square must be made with solder to the head of the IC socket where the pin wire is heading to. Therefore, capacitors, resistors and transistors soldered to the IC to complete the circuit (Kraslawski & Turunen, 2013). Another disadvantage is that, low current is associated with few number of mA, thus reducing working capacity of the machine. Prototyping environments and processes regarding to a computer system Environment is a key factor that should be considered before buying and setting a prototype system. For instance, a computer is one of the electronic gadgets that require sensitive attention to be considered. Therefore, wrap wire method and printed circuit board are used because they are safe, highly reliable and so on. Computers requires a steady flow of current such that, connection of wires from a power supply to the entire system should be very competed to avoid failure of current from reaching the destination. Additionally, printed circuit board helps machines to keep steadiness flow of current to the junior elements such as transistors and capacitors which maintains functioning of a computer. In a computer system there two types of prototypes namely, hardware prototype and software prototype (National Research Council, 2008). Hardware prototypes are mostly concerned with fixing all the physical functional parts of a computer. These parts include motherboard elements, monitor, a nd switches among other physical part of a computer. On the other hand, software prototypes are concerned with installation of programs, such as micro soft office, VLC, internet among many programs, as one can prefer (Russell, M. T. (2008). Defining an accessibility technology for the prototype in a business In order to achieve desirable and accessible prototypes many companies have found it as a
