Accounting Systems Design & Development - Essay Example Therefore, in an organization a steering committee plays the role of a decision maker (Shelly and Vermaat, 2010, p. 420). In the context of a system development project, the roles of the steering committee are as follows: The steering committee takes the responsibility for the feasibility of the project, developing the business plan. It ensures the scope of the project aligns with the need of the customers or the stakeholder groups. The steering committee also assists in the process of evaluation of project risks and the approaches of project risk management. The committee also provides guidance to those involved directly in the project. The guidance is offered mainly in the field of business issues related to the success of the project. (b) Discuss one advantage and one disadvantage of phased-in and direct switch-over implementation strategies. Solution: Phased-in implementation can be defined as a process of changeover from a preexisting system to a new one. The phased-in strategy has to move across a number of stages in order actually implement it. Advantages: Through the phased-in implementation process, it is possible to develop an overall implementation plan and further test it in small scale employing the production data. Apart from that, it also ensures establishing tractable and reasonable measures of success. Furthermore, it institutionalizes the process as it takes place. The changes in the process of implementation can be easily incorporated in the strategy through the process of familiarization. Also, the team members become the actual functional owners. The changes in this process are gradual and, therefore, easy to get accustomed to. Disadvantages: The biggest disadvantage of phased-in implementation strategy is that the process of implementation is very much time-consuming. Also, the implementation strategy is comparatively slower than the direct implementation strategy. The implementation process differs on a project-to-project basis. The impac ts of the implementation are not visible readily and have to wait till the results appear. In this implementation strategy, it is very difficult to maintain the momentum of the team members until and unless a situation of urgency is reached. Direct Switch over Implementation Strategy The direct switch over implementation strategy is about the direct switchover from the old system to the new system (ISRD group, 2006, p. 315). Some of the advantages and disadvantages are illustrated below: Advantages: The process of implementation is extremely fast as compared to the other forms of implementation strategies. Sometimes, the implementation process is completed within a week or is implemented overnight. Disadvantages: Sometimes, huge delays may occur due to absence of any scope of reverting. The system becomes unfamiliar to the user. It does not provide any option by which the old and new systems can be compared. 2. Using the Table provided, classify the following control activities as g eneral or application and explain your reasoning, (a) Employees have a password to gain access to the system. (b) When sales are entered the system retrieves customer details based on the customer number. (c) A check is performed to identify if all cheques can be accounted for.

Critical Annotated Bibliography Tranexamic Acid Essay

Critical Annotated Bibliography Tranexamic Acid - Essay Example Amandip Singh is also a doctor in the department of anaesthesiology at DMCH. The researchers assert that tranexamic acid significantly decreases blood loss after operation and reduces the need for blood transfusion among students after undergoing total knee replacement (TKR).According to the researchers, Tranexamic acid, which is a synthetic derivative of amino acid lysine, is an effective antifibrinolytic agent. The acid is may reversibly block lysine-binding sites on the plasminogen molecules, thus hinder the formation of plasmin. Other researchers have showed increased use of tranexamic acid in orthopaedic surgery due to its safety, efficacy and low cost. The research was conducted in a tertiary health care facility after obtaining approval from the hospital heath ethics committee with informal consent taken from patients involved in the study. The researchers used randomized double-blinded study involving 40 patients scheduled to undergo unilateral TKR for osteoarthritis. Three s urgeons who had experience in the field to ensure validity of the test conducted the study. The first half of the population was injected with 10mg/kg of tranexamic acid. Conversely, the placebo group underwent the same procedure only that normal saline was used instead of tranexamic acid. ... It was concluded that routine administration of the acid was beneficial to patients undergoing operation. The limitation of the research is that it involved a limited number of populations. Also, the researchers did not monitor the plasminogen levels, D-dimer, thromboelastography, and fibrin degradation products. In addition, the researchers failed to measure hemoglobin levels of transfused blood and weigh sponges, which could have affected the accuracy of calculations. The text did not have sufficient clinical evidence and literature supporting the use of tranexamic acid in preventing preoperative blood loss. The relevance and usefulness of the text to my research is that it informed on the importance of the Tranexamic acid in reducing blood loss during operations in patients. Sekhavat, L., Tabatabaii, A., Dalili, M., Farajkhoda, T., & Tafti, A. (2009). Efficacy of tranexamic acid in reducing blood loss after cesarean section. The Journal Of Maternal-Fetal & Neonatal Medicine. Vol. 22(1), 72-75. The authors of this research journal are medical practitioners at the department of obstetrics and gynecology at Shahod Sehud Hospita, and Health Services, Yard, Iran. They have the ability to produce credible research that can be used in any academic research. The argument presented by the researchers is that cesarean section (CS) rate has been on the increase among women delivering and that CS posse many complications as compared to the normal vaginal birth due to complications related to postpartum bleeding. The medications that have been used to reduce bleeding include prostaglandins, oxytocin, and methylergonovine. The researchers however feel that tranexamic acid, a synthetic derivative of the amino acid lysine that has been applied for several years in the
