The proposed solution will allow easy way of interacting with Knott End Marine Engineering so that all the necessary transaction can be carried out successfully. The basic components that are associated with the proposed resolution includes stock control system, accounts system, ordering processes and repair management system. Each system will contribute towards the growth of the organization. It can be stated that the successful introduction of the system will lead to managing the operations much more efficiently. These will provide with high advantages and will also address the functioning that are expected within the system. The identified object associated with the proposed high-level solution are item, purchase, payment, customers, repair, Chandler, and worker. Knott End Marine Engineering will achieve high advantage with the successful introduction of the new system. The new system will be capable of tracking all necessary objectives and operations.

Project Diary Detailing 

Object oriented modelling is the approach that has been utilised for the purpose of analysing the basic requirements associated with the system. It has been ensured that all the necessary factors are being considered while developing the design. The new system will offer a better way of handling the basic components (Maylawati, Darmalaksana and Ramdhani 2018). With the help of object-oriented approach, it became easy to identify the data and processes associated with the object. This is similar to agile methodology as these offers the iterative development approach and ensures that all basic requirements are being fulfilled successfully.

Object oriented approach helps in viewing the system from a bottom of view. These is responsible for combining data and processes together into object. With the help of an information system, it becomes easy for object the oriented analysis to design the system. The key objects associated with a system can be customers, contracts, dental agreement or suppliers (Padhy, Satapathy and Singh 2017). Object oriented programming allows easy way of developing system requirements with the help of unified modelling language. While carrying out this assessment the focus was to successfully analyse the system requirements using object-oriented approach so that it becomes easy to improve the system quality and productivity. With the successful utilisation of object-oriented approach, it became easy to achieve high efficiency (Balykhin et al. 2018). Hence it can be stated that the decision over selecting the approach has not only helped in enhancing the business operations but has also provided ways to iteratively carry out operations.

The major advantages that are expected to be obtained with the successful utilisation of object-oriented approach are problem-solving capability, flexibility with the help of UML diagrams, reuse of data and a better analysis of the situation (Blaha 2018). It is expected that the successful utilisation of the selected approach will not only help in developing an efficient system but will also ensure that the basic aims associated with the organisation are being fulfilled successfully. Knott End Marine Engineering organization will be capable of achieving high advantage with the help of the selected system analysis and designing method.
