Indeed, the late identification of performance bugs may imply time-consuming debugging, expensive reworks and potential technical debt. To get suppliers and stakeholders aligned to your new ways of working, they must understand how an iterative approach works and be tuned in it to give feedback at regular intervals. In order to formalize the study, we used the five ethnographic dimensions, as proposed by Sharp et al. If the Agile Methodology could solve the issues arising from the previous software methodology, then implementing Agile would be an excellent idea. performance tests were executed before each software release. Nexevo In our study, we were interested in understanding the practices of performance assurance as practitioners were interested in improving such practices. Often, in case of ambiguous PR description, architects or software developers helped the team in this process. Agile software development is a set of iterative and incremental software engineering methods that are advocated based on an "agile philosophy" captured in the Agile Manifesto (Fowler and Highsmith, 2001). They often have personalities that will clash, which affects the communications and the companys progress in the long run. In particular, we encourage future studies to investigate performance assurance practices and challenges in other Agile organizations with different characteristics (e.g., domain, organization size, development methodology) to further strengthen (or debunk) the validity of our findings. However, when it comes to more prominent organizations, it becomes a challenge. Performance web tests, instead, involved a series of HTTP requests that simulated a single user interaction. Product Owners try to introduce new requirements, and even the Scrum Master can start to interfere too much. In this way, the team loses dedicated support and accessibility to the Scrum Master as they are busy stretching themselves on several teams. Differences between two organizations provided useful contrasts for the data analysis. While functional tests were continuously executed, both in the continuous integration pipeline and in nightly builds, performance tests were executed at most once per release. A project manager generally has to go through a hierarchy of a pyramidical system. Agile's idea emerged when it was started as a set of principles for software development to write and release code iteratively. Alsaqaf et al. 2013). IEEE Softw 19 (3):2021. In an early study, Ramesh et al. Note that epic is the larger unit of work in Scrum, and it is used as a placeholder that represents work that cannot be finished within a sprint (i.e., 3 weeks). 2023 Please be informed, these are our recommendations. (2021). After setting up the environment (i.e., the virtual machine, the MESPlatform instance and its databases) and launching performance tests, the tester found that PR targets were not met. Hence, a clear and commonly shared definition of the amount of effort devoted to these activities is crucial to enable a reliable performance assurance process. Performance testing automation also implies to consistently establish whether a test is passed or not (Fagerstrm et al. Self-assignment of tasks has also been observed in open source software (OSS) development in both commercial and non-commercial projects (Crowston et al. The research presented four common categories of issues and challenges of the Scrum method, and management guidelines to help organizations that are already using the Scrum method or planning to employ it in the future. Adapting the scrum framework for agile project - ScienceDirect Figure4 outlines the performance debugging process as observed in the ChogoRi team. At the end of this process, 12 architecturally relevant operations PRs were selected. Scrum Sprints: Everything You Need to Know | Atlassian Computers in Human Behavior 51:915929. The best way to solve impediments outside the Scrum team is to invite them to the appropriate events to keep them aware of their stakes in those events. Challenges in agile software development: A systematic literature In order to guarantee the quality of our descriptions, we took into account data gathered from different sources, e.g., photographs, digital copies of documents and hand-written notes. https://doi.org/10.1016/j.chb.2014.10.046. According to the quality assurance specialist, many PRs were probably outdated and related to old versions of the product. In: Proceedings of the 15th International Conference on Mining Software Repositories, Association for Computing Machinery, New York, NY, USA, MSR 18, pp 119130 https://doi.org/10.1145/3196398.3196407, Laaber C, Wrsten S, Gall H C, Leitner P (2020) Dynamically reconfiguring software microbenchmarks: reducing execution time without sacrificing result quality. Further empirical studies are needed to investigate whether this is common problem in ASD, and to identify potential best practices. While they are supposed to be the two sides of the same coin, they put efforts towards the goal of the Product. | We distilled three key challenges when trying to improve the performance assurance process: (i) managing performance assessment activities, (ii) continuous performance assessment and (iii) defining the performance assessment effort. Challenges are always faced whenever an organization steps up and implements Agile as its way of working. . The email survey was used to refine interview questions; all of the interviews were audio-taped and transcribed, and later coded for analysis. In order to perform the first activity, a meeting was held involving all architects and product owners to identify a subset PRs for automation. The use of the scrum framework, a specific set of agile principles and practices for self-organizing cross-functional teams in software development projects, is currently being expanded to other types of organizations and knowledge management processes. Making a note about the challenges that may come along the way while implementing Agile and discussing the ways to overcome beforehand could prove a crucial step in deciding the success or failure of Agile. 2016). Following the example of other organizations (Alsaqaf et al. After these meetings, two activities were identified to improve the performance assurance process. . The consistency of our results with the ones presented in other studies gives us confidence that the main findings of this study are portable to other organizations. An in-depth case study was conducted in two organizations where the Scrum method was fully integrated in every aspect of two organizations' software development processes. 2016; Fitzgerald et al. The description contained the performance testing type (e.g., UI, load test), the description of system operation(s) under test, and a set of testing scenarios along with their detailed descriptions (e.g., machine specs, number of concurrent users). This lack of performance feedback during development might hide potentially harmful performance issues, which could eventually lead to expensive maintenance activities. (2020b), which found that different practices are adopted to document NFRs (e.g., user stories, Definition of Done, acceptance criteria, documents, artifacts, prototypes and also face-to-face communication). While interruptions can help in task completion . > Indeed, ethnographic studies are often criticized to have a weak external validity, i.e., do not necessarily generalize to other contexts (McGrath 1995). Instead of telling people what they need to do, allow people to solve their problems. This lowers the waiting time to remove the functionality, which was from months (years sometimes). Indeed, simply understanding practice may not be enough to satisfy the purpose of our research, as we aim to also understand the challenges in improving the performance assurance process. Based on the size and importance of the new item, the backlog item is then prioritized into the product backlog. One of them was filled up with user stories by the product owner and represented the customers business desires. 2019) to identify mechanisms behind the challenges of managing NFRs in large-scale distributed Agile projects, and practices used to mitigate the impact of these challenges. Empir Software Eng 27, 74 (2022). Many companies have the parameters to measure the success of Agile Methodologies, such as counting the number of companies that have transformed into Agile recently and how many projects are following the new methodology. The organization has to list out all the reasons and expectations that they expect Agile to change. Please try again. But during the planning of Implementation, they do not strategize the aftermath or long term goals for implementing Agile and how the company would move forward if the small pockets of Implementation are successful. In this section, we first describe the performance assessment process, as it was observed in the case organization, and then we report problems that arose from the adoption of such process. To best of our knowledge, the only attempt to tackle this problem was made by Ho et al. Agile approaches help software development project teams to better meet user needs and ensure flexibility in uncertain environments. In this blog post, we offer inspiration for when to use these cases and give suggestions for what Liberating Structures to try as conversation starters. The definition of a clear and commonly accepted balance between performance assessment activities and other development activities is essential to enable a reliable performance assurance process. However, many PRs were rarely tested due to time and resource constraints. INTRODUCTION Agile software development is a relatively new approach for software development. Agile Implementation in a large organization would be a massive transformation for the employee and the customers. In the second round, the codes were reviewed, and the concepts were organized by recurring themes. The importance of attending to the ordinary details of life lies in the role these details play in relation to how the everyday tasks are addressed (Sharp et al. 2016). Four main criteria were used to identify this subset: the relevance of the system operation under test, the ease of automation, the time effort required to configure and run tests, and the robustness of tests in terms of maintenance.
