IT strategies enhance the value of the firm

IT strategies enhance the value of the firm and the efficiency of its processes. I have encountered a number of real-time examples where the companies have gained a competitive edge over others by aligning their IT strategies with business objectives. For example, McDonalds’ business objectives are to increase its market share, attract more customers, and increase sales. It has aligned its IT strategy with the business objectives by introducing Gamification strategy. As per this strategy, McDonald's installed interactive digital billboards on the busy squares. The customers could participate in the game displayed on the billboard by getting connected through the Bluetooth devices of their smartphones. McDonald's experienced a 30% increase in the profits. It’s market share expanded by 40% (Boykiv, 2015).

system development cycle

It is a structured framework includes sequential processes that develop information systems. The agile model for SDLC is a more modular and flexible approach. Agile approaches software development in incremental cycles, called sprints. Each sprint is iterative, and code is designed to be modular. An effective (SDLC) system development cycle should result in a high - quality system, which meets customer expectations, completes timely and cost - effective evaluations, and work in the current and planned IT infrastructure effectively and efficiently.
The System Development Life Cycle is a conceptual model that covers policies and procedures for the development or alteration of systems throughout their life cycles.
On the exam, SDLC focuses on security in every phase. This model is broader than many application development models, focusing on the entire system, from selection/development, through operational requirements, to secure disposal. There are many variants of the SDLC, but most follow (or are based on) the National Institute of Standards and Technology (NIST) SDLC process.
In contrast, the agile model for SDLC is a more modular and flexible approach. Agile approaches software development in incremental cycles, called sprints. Each sprint is iterative, and code is designed to be modular.
