The Agile software development process offers many potential benefits, including a design approach that allows frequent customer input, rapid development of functionality, and the ability to identify and resolve potential misunderstandings in design requirements. This process has generally been highly successful and offered many benefits to the software development industry. It is being adopted by an ever-increasing number of industries and used for applications beyond software development, including hard ware development, training materials, and marketing materials, to name a few examples. This paper describes a project to examine the integration of Human-Centered Design principles with the Agile process, and evaluate the appropriateness of this integrated process for safety and mission critical systems design.

Development Methods

Agile development methods are widely utilized in software development. There is a growing interest and effort to introduce them to other areas of technology, such as development of space systems. Space systems are typically safety- and mission-critical and therefore their development is strongly regulated and standardized. European Cooperation for Space Standardization (ECSS) has created a collection of standards which are extensively followed mainly in European space projects. In this paper, a review and discussion are presented to find out the conflicts between the agile development and the ECSS standards. The presented analysis and discussion show that the ECSS standards do not fully prevent the utilization of agile methods. However, there are aspects to be taken into account in the development methods, contracts and tailoring of standards.

Software testing is a continuous process during the software development stages to ensure quality software products. Researchers, experts and software engineers keep going on studying new techniques, methods and approaches of testing to accommodate changes in software development because of the flexible requirement along with the changing of technology. So, developers and testers need to have effective methods, tools and approaches to create a high-quality product at an efficient cost. This paper provides an effective approach for context-driven testing (CDT) in an agile software development process. CDT is a testing approach that supports the tester to choose their testing techniques and test objectives based on specific contexts. The aim of this paper is to propose an effective approach for implementing the CDT in practice, called CDTiP. Through an analysis of two case studies using an agile development process with different contexts, we validate the effectiveness of the approach in terms of test coverage, detect errors, test effort. The empirical results show that CDTiP is suitable for the agile development process that can help the tester to detect defects faster at minimum cost. The results of this method have been applied at Enclave, an ODC Software Engineering company, on real projects.

First Time

The concept of reuse is applied in one of the agile development methodologies called the scrum. Sprint is a single functionality and the result at the end of the sprint functionality is derived as the shippable or bugs. This paper makes an attempt to use the concept of reuse in the agile software development to meet the dynamic change of customer requirements in banks. A banking project is created using both waterfall model and scrum model, and the knowledge gained is stored in the ontology-based repository for the first time. Again, the same project is created for different vendors using the ontology-based repository. The result shows that maximum sprint is reused and all the knowledge gained is stored in the form of ontology. This ontology helps identify the shippable component of each sprint which is a small executable functionality. This leads to less cost and time to deliver the product. The main aim is to increase the availability of the reusable artifacts, which lead to increase the reusability of the developer. The experimental results show improvements in the performance of retrieving the components for the software development.

Causes Of Failure

Safety-critical systems (SCS) are the most significant systems that affect our daily life in many areas such as flight control systems, railway systems, medical devices, nuclear systems, and military weapons. SCS failures could result in losing life or serious injuries. Improving the practices during development phases of SCS can reduce failures up to 40%, thus resulting developers to follows specific development practices and techniques. Developers should improve safety-critical system development (SCSD) by taking into account all factors and understanding the causes of failure. Previous studies have highlighted the causes of failure during the development of SCS, but for specific areas such as designs, requirements, or the human factor, while developers need to know the causes of failure in all areas and the relationship between them clearly and comprehensively. This research aims to analyze SCSD characteristics and discuss performance improvement as well as causes of failure. This paper proposed a guideline that helps developers reduce the causes of failure during SCS development. This guide has four characteristics, each with a role in improving SCSD and reducing causes of failure.

The Rational Unified Process (RUP) method is an iterative and incremental software development method that focuses on architecture. The RUP method will be used in the development of a medical check-up information system on a Citra medical center because this method is proactively able to resolve the project risks associated with the client's evolving requirements requiring careful change request management. Less time is required for integration as the process of integration goes on throughout the software development life cycle and the development time required is less due to using of components over and over. RUP involves The client’s in The system development process, so the result will be accordance with client  wishes. The system built is expected to make it easier for employees to manage patient data from anywhere and anytime.
