Software development projects have been blamed for being behind schedule, cost overruns, and the delivery of poor quality product. This paper presents a simulation model of a data warehouse to evaluate the feasibility of different software development controls and measures to better manage a software development lifecycle, and improve the performance of the launched software. This paper attempts to address the practical issue of code defects in each stage of data warehouse application development. The author has compared the defect removal rate of their previous project to the newly proposed enhanced project development life cycle that uses code inspection and code scorecard along with other phases of software development life cycle. Simulation results show that the code inspection and code score-carding have achieved a significant code defect reduction. This has also significantly improved the software development process and allowed for a flawless production execution. The author proposes this simulation model to a data warehouse application development process to enable developers to improve their current process.

This paper takes a deeper look at data breach, its causes and the linked vulnerability aspects in the application development lifecycle. Further, the Vulnerabilities are mapped to the software development life cycle (SDLC) involving requirement elicitation, design, development, testing and deployment phases. Being aware of exact SDLC life cycle where the vulnerabilities are injected, suitable security practices (countermeasures) can be adopted in delivery methodology, which can control the eventual data breaches and safeguard the application from security perspective. Our research focuses on Evolution of Vulnerabilities through the application development life cycle, and we have leveraged “Inverted Tree Structure/Attack Tree” and “Affinity Principles” to map the vulnerabilities to right Software Development Life Cycle.

DevOps is the combination of cultural mindset, practices, and tools that increases a team's ability to release applications and services at high velocity. The development and operations teams always have a conflict around the scope of responsibility. With these differences the quality and speed of delivery across software Development Life Cycle is negatively impacted. DevOps is about removing the barriers between two traditionally delimited teams, development and operations. With DevOps, these two teams work together to optimize both the productivity of developers and the reliability of operations. They strive to communicate frequently, increase efficiencies, and improve the quality of services they provide. They take full ownership for their services, often beyond where their stated roles or titles have traditionally been scoped. Transitioning to DevOps requires a change in culture and mindset first. It is quite difficult to persuade a whole company to change its culture at once. This paper aims to bring different phases of software development lifecycle into DevOps implementation strategy and presents a comprehensive collection of leading tools used across Software Development life Cycle to automate and integrate different stages of software delivery. This paper also highlights on DevOps practices which span across different phases of the Software Development Lifecycle and how those can be implemented with different tools available.

A fundamental reality of application development is that the user interface is the system to the users. Software development process should reflect this fact. When you ask how user interface development should be reflected within an software development lifecycle (SDLC), you quickly discover that it affects all aspects of software development from requirements through to system delivery. This chapter discusses how user interface development should be reflected in a mature software process and overviews a collection of techniques for each phase of software development, showing how user interface development can easily be integrated into the overall software process.

Abstract: The Software Development Life Cycle (SDLC) refers to a methodology with clearly defined processes for creating highquality software which are cost effective and reliable. This method of software developing process is quite systematic and structural. SDLC defines the framework that has different activities and tasks to be administered during the software development process. Software development process is quite complex, and to do it without any proper planning would be inefficient. So, we use these SDLC models to make the Software development process simple and systematic. There are various software development life cycle models that are used in the software development process, all having their own advantages and limitations. In this paper, we have included six of these SDLC models - Waterfall Model, Spiral Model, V Model, Agile Model, Iterative Model and Rapid Application Development (RAD) Model. These Software Development processes have their own Advantages and Disadvantages, and the main purpose of this paper is to explain these models and know the difference between them.

In the game of Golf, a player is challenged to take the minimum strokes to complete a round of 18 holes under varying playing conditions. Players use different clubs depending on their skill levels to achieve the desired distance while taking shots at the golf ball from the start (tee off) to the hole (pin). Unlike other games which have a standardized playing area, the terrain in a golf course comprises of various natural and manmade features viz. fairways, bunkers, trees, water bodies etc, which increase the difficulty level of the game and keep the players challenged.The game of golf has a fascinating similarity to a software development life cycle. If the holes on a golf course are considered akin to milestones in a development project then most of the Software Engineering models focus on software development in groups. Thus, we propose SOLF i.e Software Development Lifecycle model based on Golf, as a SDLC ideal for individuals or a small group of 2-3 developers. The proposed model is easy to comprehend, flexible and optimally adjustable in a dynamic environment.SOLF divides the project into 18 stages wherein each stage of the project will have 3 to 6 tasks which are required to be completed within a fixed timeline. The stages are managed by creating checklists at the start akin to the pre-shot routines in golf and the customer feedback is received on reaching each of the milestones similar to applause in the game of golf. Terrain of the golf course is reflected as risk list which are varying for each of the stages.SOLF achieves 10x speedup in software development and research projects as it creates an environment of challenges and drives the developer towards self excellence. It also inculcates a spirit of competition and sportsmanship by challenging the developers on various 'terrains' of development.
