As software systems grow in size they will also grow in complexity. If the increased complexity is not managed the system will be increasingly difficult to maintain. The effect of unmaintainable software is even more distinct when using a agile development process. By increasing the maintainability of the system these problems will be dealt with and the system can be extended with sustained efficiency. This thesis will evaluate the development process of a modern, agile company in order to find changes that will promote increased maintainability. The result is an modified process that will increase the maintainability with the smallest possible overhead for the development organisation. The result is based on earlier studies of development technologies that have proven to increase the maintainability. The implementation of these technologies are adjusted to fit the development team, and some of the technologies that are not suitable for the team are rejected.

I present a systematic method to primary develop existing black oil fields. This method uses integrated reservoir development workflow (IRDW) that relies on integrated asset model (IAM). Developing any existing field means providing a plan that generally serves the development goal(s) specified by management. However, serving the development goal(s) by itself does not guarantee an optimal development plan. Plans that do not rely on an IAM are less accurate. Some plans do not include economics in their evaluation. Such plans are technically accepted but usually impractical or unprofitable. Plans that only evaluate the field based on current, or short-term, conditions are potential candidates for bottlenecks, thus costly reevaluations. In addition, plans that do not consider all suitable options are misleading and have no room for optimization. Finally, some plans are based on “rules of thumb,” ease of operations, or operators’ preference, not on technical evaluation. These plans mostly lower long-term profitability and cause further production problems. To overcome these problems, project management must form a multidisciplinary team that uses the IRDW. The IRDW guides the team through its phases, stages, and steps to selecting the optimal development plan. The IAM consists of geological, reservoir, wellbore, facility, and economic models. The IRDW dictates building an IAM for the base (do nothing) case and for each development plan. The team must evaluate each scenario over the lifetime of the field, or over the timeframe the management specifies. Net present value (NPV) and Present value ratio (PVR) for all options are compared to the base case and against each other. The optimum development plan is the one that have the highest NPV and highest PVR. The results of the research showed that forming a multidisciplinary team and using a LDFC saves time and it guarantees selecting the optimal development plan if all applicable development options are considered.

This thesis deals with the information system in the context of business processes. The work processes are analyzed, their interconnection with the information system and where it is possible to improve the information system. To take into account a number of criteria and are designed such changes that will help employees and customers. The main idea behind the changes is to assist in the automation of processes, less administrative burden on staff and supporting tools for managerial decision-making. In conclusion, the benefits are reviewed and assessed intensity changes.

Background. In video game development, efficient destruction tools and workflows were crucial for creating engaging gaming environments. This study delved into the fundamental principles of 3D object properties and interactions, reviewed existing destruction techniques, and offered insights into their practical application, with a specific focus on Embark Studios’ destruction tool.  Objectives. This study focused on the optimisation of an existing destruction tool to enhance efficiency and integration within a gaming company’s pipeline. The key objectives included reducing execution time, and improving designer workflow. The study utilised performance counters and Unreal Insights profiling to identify and optimise hotspots in the destruction tool. Additionally, the performance of the op- timised tool was measured and compared to the existing one to quantify efficiency improvements. An expert evaluation with designers at Embark Studios was con- ducted to assess the impact of the optimised tool on their workflow.  Methods. The existing destruction tool was optimised primarily through parallelisation. The efficiency of the optimised tool was evaluated both empirically, by measuring the execution time, and subjectively, through an expert evaluation involv- ing three professional level designers.  Results. The optimisation significantly reduced the execution time of the destruc- tion tool. Feedback from the expert evaluation indicated that the optimised tool could enhance designer efficiency, particularly in rebuilding the destruction graphs. However, the performance of the optimised tool was found to be hardware-dependent, with varying execution times observed across different hardware configurations. Conclusions. This study presented an optimised destruction tool which demon- strated improved performance and efficiency, validating its suitability for integration into the pipeline of game development. It was proposed that future work could further optimise this tool and explore its performance across diverse hardware con- figurations.
