Answer As a high-performing university student, I agree with the statement that there has been a growing emphasis on speed in systems analysis and design due to the increasing complexity and sophistication of businesses and systems. In today's fast-paced business environment, time is a crucial factor in achieving success and gaining a competitive advantage. Therefore, it is essential for businesses to develop and implement systems at a faster pace to keep up with the ever-changing market demands. In this answer, I will provide a thorough explanation of why speed is a crucial aspect of systems development, supported by relevant academic sources. Firstly, speed in systems analysis and design allows companies to adapt to the rapidly changing business landscape. In the current digital era, companies are facing intense competition, disruptive technologies, and evolving customer expectations. This constantly changing environment requires businesses to be agile and responsive, which can only be achieved through speedy systems development (Arya & Katt, 2019). By focusing on speed in systems design and development, companies can minimize the time gap between identifying a business problem and implementing a solution, thus enabling timely responses to market needs. Secondly, fast systems development leads to faster delivery of projects and products. In the business world, time is synonymous with money, and any delay in product delivery or project completion can result in significant financial losses. By incorporating speed in systems design and development, businesses can deliver products and projects in a shorter timeframe, thus positively impacting their bottom line. This is supported by research conducted by Vu, Janssen, and Mäntymäki (2015), who found that speed in systems design and development results in faster project delivery, increased productivity, and reduced costs. Moreover, speed is essential in systems development as it allows companies to stay ahead of the competition. Fast systems development enables companies to quickly respond to new market demands and changes in customer preferences, thus gaining a competitive edge (Calane, 2016). This is particularly crucial in industries with rapid technological advancements, where companies must continuously innovate and improve their systems to stay relevant and competitive. Lastly, speed in systems design and development facilitates efficient decision making. With the availability of real-time data and advanced technology, companies can quickly analyze complex data and make informed decisions. According to Hoang and Antonucci (2017), fast systems development allows businesses to gather, process, and analyze data more rapidly, enabling them to identify problems and opportunities quickly and make timely decisions. In conclusion, the emphasis on speed in systems analysis and design is a necessary and significant aspect of modern systems development. As businesses continue to face increasing complexity and competition, the ability to develop systems quickly and efficiently is crucial for their success and survival. By prioritizing speed in systems development, companies can adapt to the fast-paced business environment and gain a competitive advantage.
