Just like any other material asphalt too has disadvantages.Where advantages are there, disadvantages will also be there. None of the materials have only advantages.So, if you're using asphalt for your surface paving then you should emphasize to know disadvantages as well with the advantages Martin MBO Disadvantages. Here's a couple of weaknesses in the MBO assumption base that I use: 1. It emphasizes the setting of goals over the working of a plan. 2. It underemphasizes the importance of the environment or context in which the goals were set. That context includes everything from the availability and quality of resources, to relative buy-in by leadership and stakeholders Even modern lighting benefits from smart controls. Lighting systems can be automated to stay on for certain periods of time. They can switch on or off on predetermined schedules or be triggered by sensors. Programmable relays also control industrial equipment, building systems and more
