Development of management information system on social compliance in RMG sector using open source system architecture
(Institute of Information and Communication Technology, BUET, 2009-04) Alauddin Ahmed; Islam, Dr. Md. Saiful
In addition to price and quality of the product, and delivery period, all major garment buyers, nowaday, have set their business policies focusing on compliance of factories with their corporate code of conduct. Hence, social compliance of Ready Made Garment (RMG) factories is very crucial for ensuring the export of their products in the developed countries. A Management Information System (MIS) can function significantly in doing a social compliance audit of garment factories and can be used for information storage, handling, processing and retrieval of data for improving the services provided by any organization. The MIS will also facilitate quick decision making for overall functional improvement. To establish a structured system for reporting and monitoring of social compliance status of RMG factories through a standard, logical and comprehensive flow of information a MIS has been developed under this project. The MIS has been assisting different organizations carrying out social compliance audit of RMG factories. The system has been implemented in open source environment using Java and MySQL. The MIS has been designed with a front-end application and backend database system. The design of forms and self descriptive front-end panel with appropriate captioning ensures the user friendliness of the system. The system has been tested based on the data and information collected from organizations who are involved in assessing the social compliance of RMG factories. First of all some adequacy criteria such as grading of factories on different headings based on available input data have been chosen. The execution-based, more specifically, the specification-based techniques used for testing, focuses on the functional and non-functional requirements of the software. Test cases are black-box tests which have been created without knowledge of the software's source code. Based on the execution result of the test cases the software has been fine tuned for bugs and errors. The MIS provides status of factories on fifteen major areas and the outputs are helpful to the management for quick and scientific decision-making and improving the services to achieve the required standard.
Impact of water safety plan on municipal water supply system in selected pourashavas
(Department of Civil Engineering (CE), 2017-01) Alauddin Ahmed; Mujibur Rahman, Dr. Md.
An effort was made in this research to assess the impact of WSP in municipal piped water supply systems based on identified key indicators. A quality assurance tool was developed to carry out auditing of WSPs that indicates the maturity of any WSP, implemented in urban-piped water supplies. Finally, the QA audit tool was used in selected two municipal towns to carry out a gap analysis of the implemented WSPs in comparison to ideal scenario. The results of indicator based WSP impact assessment and WSP audit were validated against findings from water quality test results and household survey findings. The key research questions that were answered through the research include whether WSP have affirmative impact on realizing health-based outcomes and if WSP implemented in different type of urban-piped water supply systems can be audited on a common ground so that maturity of different WSPs can be compared. The indicator based assessment showed positive outcome and impact of WSP in both Chandpur and Chapai-Nawabganj Pourashava. In Chandpur, level of operations and management practices increased to 24 from 8 out of 40 points. The cost recovery has improved as revenue collected per consumer has increased to 128 BDT/consumer from 68 BDT/consumer in last one year. Stakeholders’ knowledge and understanding have also increased from 12 to 19 out of 25. Percentage of treated water samples compliant with microbial water quality targets increased to 90 with WSP compared to 80 without WSP. Diarrheal incidence rate also decreased to 24 percent from 34 percent at that stages. Operations and management practices in Chapi-Nawabganj increased to 17 from 8 out of 40 points. However, operating cost of produced water increased by 0.34 BDT/cubic-meter mainly due to increase in electricity tariff over time. Understanding of water supply system by the stakeholders has been increased from five to 25 on a scale of 25. Eighty percent water samples are compliant with microbial water quality targets with WSP, which was 50 percent without WSP. Diarrheal incidence rate has also gone down from 37 percent to 29 percent. WSP audit performed using the QA tool scored 93 and 98 out of 120 in Chandpur and Chapai-Nawabganj respectively. This indicated that the WSP maturity in both the water supply systems stands as ‘Good’. The QA tool has high prospect to be used in the country and region as WSP audits become increasingly important due to its integration with regulatory environment. The tool can be further tailored to suit all scheme types and levels of sophistication.
