The Globe analyzed the career paths of 750 of the highest ranking generals and admirals who retired during the last two decades and found that, for most, moving into what many in Washington call the “rent-a-general’’ business is all but irresistible.... From 2004 through 2008, 80 percent of retiring three- and four-star officers went to work as consultants or defense executives, according to the Globe analysis. That compares with less than 50 percent who followed that path a decade earlier, from 1994 to 1998.
The word, Junoon, comes from the Urdu/Arabic language... The current English language lacks a single word to describe the concept, so the best we can do is describe it in three words: Junoon is a state of obsession. It's a trasnformative, all-consuming mania: a kind of craziness, if you will, that envelops your mind and heart to achieve yoiur goal.Anyone who has ever experienced Junoon during their lifetimes will quickly recognize themselves in this book. Junoon is a fascinating term and concept, which will likely find its way into the English lanaguage and lexicon.
To live within the state of Junoon is to concentrate passionately on realizing your mission and transcending day-to-day human motivation to a degree that seems impossible to those around you. Being in this state coalesces and magnifies your ordinary strength of will and determination, and turns you into a person who rises to challenges in ways that others can't even imagine. You hold nothing back. You put your all and everything that you do, and through your investment of your entire being, you find ways to surmount the most daunting of circumstantial barriers with incredible energy.
Imagine that you're so obsessed with accomplishing something for the greater good that you feel utterly consumed with getting it done. You are inspired by a mandate from the universe, and allow nothing to stop you from achieving your objective. From morning to night, you live within your passionate concentration and desire. This is what it's like to live in, and act from, the state of Junoon.
Descriptive Analytics: A set of technologies and processes that use data to understand and analyze business performance.While descriptive analytics provide a starting point for understanding problems and performance, the more significant purpose and objective of analytics is to achieve predictive and prescriptive findings via higher levels of technique. Make certain that your business analytics strategy is not short-changing decision makers by concluding with descriptive findings alone. Said another way, insist that your business analytics leaders and teams have the training and discipline to go the distance into all forms of advanced analytical methods and techniques as required. The questions posed above under each level of inquiry can provide the interrogative tools for evaluating your firm's current capabilities.
Predictive Analytics: The extensive use of data and mathematical techniques to uncover explanatory and predictive models of business performance representing the inherit relationship between data inputs and outputs/outcomes.
- Standard reporting and dashboards: What happened? How does it compare to our plan? What is happening now?
- Ad-hoc reporting: How many? How often? Where?
- Analysis/query/drill-down: What exactly is the problem?
Prescriptive Analytics: A set of mathematical techniques that computationally determine a set of high-value alternative actions or decisions given a complex set of objectives, requirements, and constraints, with the goal of improving business performance.
- Data mining: What data is correlated with other data?
- Pattern recognition and alerts: When should I take action to correct or adjust a process or piece of equipment?
- Monte-Carlo simulation: What could happen?
- Forecasting: What if these trends continue?
- Root cause analysis: Why did something happen?
- Predictive modeling: What will happen next if?
- Optimization: How can we achieve the best outcome?
- Stochastic optimization: How can we achieve the best outcome and address uncertainty in the data to make better decisions?
The teachers’ unions are not really the problem (or solution) in my view. The problem is that the format of secondary education has not changed for one hundred years. At some point during the 21st century (and the sooner the better), society will need to consider the economic efficiencies afforded by alternative education. For example, society will soon witness the arrival of “3rd-grade-in-a-box” education technology that will far surpass the teaching effectiveness of traditional “bricks and mortar” schools. Imagine if every child in America could be mailed an education program developed by subject matter experts that effectively replaced sending one’s children to the school bus (which costs money), then on to their homerooms (we have already wasted an hour of each student’s time just getting to school), then on to several sessions of classes taking place in a school building throughout the day (including the costs of the building, maintenance, heating, air conditioning, security, insurance, and so forth), then back to their school buses (more student time and public money out the window), and finally to return home. At some point, this model for public education will be rejected by progressive families who will elect the “3rd-grade-in-a-box” alternative and keep their children home except to socialize and play sports with children in their neighborhood. The cost savings of moving public education from “bricks and mortar” to “boxed delivery” formats could be tens to hundreds of trillions of dollars over time. If teachers’ unions are against moving education forward with the emerging technology, then yes, they are part of the problem. However, the existence of teachers’ unions is not really the issue in my mind. Society needs to seek economic efficiencies from all public services, and secondary education is ripe for technological reform in the near future.
