Detailed system requirements are elicited from the user and other stakeholders requirements are further analyzed and refined, and plans and processes for managing the requirements throughout the rest of the system life cycle are developed.
Complete and comprehensive description of what and how the system is expected to perform has been developed along with an architectural representation to guide the actual design and development of the hardware, software, and interfaces
• The system's components and its interfaces with other systems are integrated into an operational whole.
• Test the system to see if it fulfills the users' needs (verification) and all of the defined requirements (validation). Testing at this phase also involves properties such as reliability, security, and interoperability.
Answer:
The FFH or “Fall from Height” is a considerable jeopardy of public health occurring globally. It has been among the crucial leading reasons of fatal and serious injuries for the construction workers (Wood et al., 2014).The following report undergoes a comprehensive study of the factors in the FFH incidents. It includes the concept map illustrating various aspects. Next two system safety tools are applied to the identified work activities.
The concept map: Utilized as the teaching and learning tool, the concept mapping illustrates the various relations among the ideas and concepts visually. Is explains the interconnection between the ideas and thus helps to structure and organize the thoughts to understand the information further. It also helps in discovering new relationships. For the “Fall from Height” it represents the hierarchical structure (Tuma et al., 2013).
This includes the complete concept with the subtopics linked. Moreover here it is serving the role of a graphic organizer utilized to represent and organize the knowledge of “Fall from Height”. It starts with the fundamental idea and then it stretches out to display how the basic concepts could be broken down into particular elements. The benefits of concept mapping: It has been serving various purposes:
Helping to generate and brainstorm latest ideas. It encourages finding the latest ideas and the propositions connecting them. It has been allowing the students It has been allowing to clearly communicating the information, thoughts and ideas. Moreover it helps in integrating the latest concepts with the traditional ones. Lastly it has been enabling to gain the improved knowledge for “Fall from Height” and evaluate the information.
Building of the Concept Map for “Fall from Height”: The hierarchies of controls are needed to be understood here. The complicated safety problems and needed to be analyzed and a proper intervention strategy is needed to be selected. Moreover the utility of the administrative and engineering controls are to be understood with the handling of manual materials (Roopak & Jagannatha, 2015). The process of implementation is to be described for the “Fall from Height” intervention strategy. The effective risks are to be eliminated here.
This indicates to the entire eradication of the exposure of the workers to the hazards. This has been making all the recognized possible incidents, accidents and the unhealthiness impossible. It must be attempted first as suggested in that concept map hierarchy as permanent solution. It must be reminded that the system safety has developed from its origin in the accident investigation. This is done through the different mitigation and prevention strategies to the complete partnership of the process of system design. This also includes the productivity and quality (Ivancic, 2014).
The set of analysis and the design tools are to be understood clearly to ensure the ease of use, quality and reliability, safety, efficiency, the satisfaction and security. This is to be done in the operation of the large and small systems across the life-cycle provided with different human, technological, operational and environmental problems. Building of the concept map: This is done by the following processes: 1. Starting with the idea of ““Fall from Height”” 2. Determination of the primary concepts 3. Ending through connecting concepts and linking the phrases and words.
The system safety tools: 1.The 5 whys: The process of 5 why’s could be helpful in the investigation of the accidents and its design. This has been utilized in conjunction with the various other processes also. This is also b smooth method to get into the original cause of the accident (Kumar & Husain, 2014). Moreover, it is possible that the pathways of inquiry might branch and then link up. The mapping of concept is a very helpful adjunct.
This is especially because of the usage of 5 Whys have been incorporating the links comprising of the details to the background materials. For instance the following consideration could be taken where the 5 Whys could be used: An old worker tripped in the ladder at construction building and broke his wrist. The same people run down from the bicycle when he was working. Here he suffered a broken leg. As he recovers from the injuries from the hospital he was supplied with the wring dose of medicine and died. 2. Hierarchy of control:
Things that are learnt: The places where the frequent and regular access to the height is needed, the permanent and the safe access must be also installed (Hatamabadi et al., 2017). For instance on any machinery or plant, the 5 Whys and the Hierarchy of controls could be the steps with handrails. While the portable equipments arte used for the temporary access, it has been crucial that has not been restricted to what has happened at the hand. For instance the hiring of the scissor lift or the cherry picker could improve the safety.
Further recommendations: Apart from the above measures the employee or factory owner or those with the duty of care should assure that the working at height has been done safely and with proper supervision. The employees qualified enough should get the appropriate training and the rules on the involved works. It is also the liability of the employers to assure that the proper equipment is required. This should be done by following the best practicing guidelines of the industry and that the tools have been in outstanding order of working.
The adhering to those regulations will never eradicate the risk of the fall. However it would make that less likely and the outcomes in the most unfortunate case scenario must be lessened substantially.
