15. What is Moore’s Law? What are its implications for business and technology?
• Many real projects have hundreds of business requirements, take years to complete, and cost millions of dollars. Gordon Moore, co-founder of Intel Corporation, observed in 1965 that chip density doubles every 18 months. This observation, known as Moore’s law, simply means that memory sizes, processor power, and so on, all follow the same pattern and roughly double in capacity every 18 months. Moore’s law states that technology changes at an incredibly fast pace; therefore it is possible to have to revise an entire project plan in the middle of a project as a result of a change in technology. Technology changes so fast that it is almost impossible to deliver an information system without feeling the pain of changing technology.
