Department of Transportation Majumdar and John F. Sowa www. But good ideas rarely implement themselves, and often the heavy hand of history means that bad practices and outdated processes tend to persist.
Even in organizations that pride themselves on having a vibrant marketplace of ideas, converting data and insights into better business outcomes is a pressing and strategic challenge for senior executives. How does an organization move from being data-rich to insight-rich— and capable of acting on the best of those insights? Big data is not enough, nor are clever analytics, to ensure that organizations make better decisions based on insights generated by analytic professionals.
Rarely is the difference in impact due to superior analytic insights or larger data sets. A central irony, first identified in by Nobel Prize winner Herbert Simon, is that when data are abundant, the time and attention of senior decision makers become the scarcest, most valuable resource in organizations. We can never have enough time, but we can certainly have too much data. Executives sometimes fail to appreciate fully the opportunities or risks that may be expressed in abstract algorithms, and too often analysts fail to become trusted advisors to these same senior executives.
Most executives recognize that models and analyses are reductive simplifications of highly complex patterns and that these models can sometimes produce overly simple caricatures rather than helpful precision.
In short, while advanced analytic techniques are increasingly important inputs to decision making, savvy executives will insist that math and models are most valuable when tempered by firsthand experience, deep knowledge of an industry, and balanced judgments.
Smart analysis can also take away excuses and create accountability where there had been none. But sometimes, as Andrew Lang noted, statistics can be used as a drunken man uses a lamppost—for support rather than illumination.
It is tempting to forget that the future is certain to be different from the recent past but that we know little about how that future will become different. Some of the most important organizational decisions are simply not amenable to traditional analytic techniques and cannot be characterized helpfully by available data.
Investments in innovation, for example, or decisions to partner with other organizations are difficult to evaluate ex ante, and limited data and immeasurable risks can be used to argue against such strategic choices.
But of course the absence of data to support such unstructured strategic decisions does not mean these are not good choices—merely that judgment and discernment are better guides to decision making.
Many organizations will find it beneficial to distinguish more explicitly the various types of decisions, who is empowered to make them, and www. Many routine and tactical decisions, such as staffing, inventory planning, or back-office operations, can be improved by an increased reliance on data and by automating key parts of the decision-making process— by, for example, using optimization techniques.
These rules and decisions often can be implemented by field managers or headquarters staff and need not involve senior executives. More consequential decisions, when ambiguity is high, precedent is lacking, and trade-offs cannot be quantified confidently, do require executive engagement. In these messy and high-consequence cases, when the future is quite different from the recent past, predictive models and optimization techniques are of limited value. Other more qualitative analytic techniques, such as field research or focus groups, and new analytic techniques, such as sentiment analysis and social network graphs, can provide actionable, near-real-time insights that are diagnostically powerful in ways that are simply not possible with simulations or large-scale data mining.
Even in high-uncertainty, high-risk situations, when judgment and experience are the best available guides, executives will often benefit from soliciting perspectives from outside the rarefied atmosphere of their corner offices.
Substantial academic and applied research confirms that decisions made with input from different groups, pay grades, and disciplines are typically better than decisions that are not vetted beyond a few trusted advisors. To reduce this gaming and the risks of suboptimization, there is substantial value and insight gained by seeking out dissenting views from nontraditional sources.
Good analysts can play important roles too since they bring the rigor and discipline of the scientific method above and beyond any data they may have. Many executives may need to confront the problem of information distortion. Often this takes the form of hoarding or a reluctance to share information freely and broadly across the organization. These practices can impair decisions, create silos, truncate learning, accentuate discord, and delay the emergence of learning communities.
In the past, hoarding and managing up have been rational and were sometimes sanctioned; now, leadership means insisting that sharing information up and down the hierarchy, transparently and with candor, is the new normal. This is true both when insights confirm existing views and practices and also when the data and analysis clash with these. Conflicting ideas and competing interests are best handled by exposing them, addressing them, and recognizing that they can improve decisions.
Learning to improve business performance through analytics is typically piecemeal and fragile, achieved topic by topic, process by process, group by group, and often in fits and starts.
But it rarely happens without strong executive engagement, advocacy, and mindshare—and a willingness to establish data-driven decision making as the preferred, even default approach to answering important business questions. Executives intent on increasing the impact and mindshare of analytics should recognize the scale and scope of organizational changes that may be needed to capture the value of data-driven decision making.
This may require sweeping cultural changes, such as elevating the visibility, seniority, and mindshare that analytic teams enjoy across the company.
It may also require repeated attempts to determine the best way to organize analytic talent: whether they are part of information technology IT , embedded in business units, centralized into a Center of Excellence at headquarters, or globally dispersed. Building these capabilities takes time and a flexible approach since there are no uniformly valid best practices to accelerate this maturation.
This is deeply ironic: we know that strong analytic capabilities can improve business results, but we do not yet have a rigorous understanding of the best ways for organizations to build these capabilities.
There is little science in how to build those capabilities most efficiently and with maximum impact. Smart decisions usually require much more than clever analysis, and organizational learning skills may matter more than vast troves of data.
High-performing teams identify their biases, disagree constructively, synthesize opposing views, and learn better and faster than others.
Relative rates of learning are important, since the ability to learn faster than competitors is sometimes considered to be the only source of sustainable competitive advantage. Forgetting does matter, because an overcommitment to the status quo limits the range of options considered, impairs innovation, and entrenches taken-for-granted routines.
Time after time, in market after market, highly successful firms lose out to new products or technologies pioneered by emerging challengers. Blinded by past successes and prior investments, these incumbent companies may be overly confident that what worked in the past will continue to work well in the future. Executives confront at least one objective constraint as they consider their approach to data-driven decision making: there is a pervasive shortage of deep analytic talent, and we simply cannot import enough talent to fill this gap.
Estimates of this talent gap vary, but there is little reason to think it can be filled in the near term given the time involved in formal education and the importance of firsthand business experience for analysts to become trusted advisors.
Much as an MBA has become a necessary credential to enter the C-suite, executives will increasingly be expected to have deeper knowledge of research methods and analytic techniques. This newly necessary capability is not about developing elegant predictive models or talking confidently about confidence intervals, but about being able to critically assess insights generated by others.
What are the central assumptions and what events could challenge their validity? What are the boundary conditions? Is A causing B or vice versa? Is a set of conclusions statistically valid? Are the findings actionable and repeatable at scale?
There is nothing automatic or easy about capturing the potential value of big data and smarter analyses. Across several industries, markets, and technologies, some few firms have been able to create competitive advantages for themselves by building organizational capabilities to unearth valuable insights and to act on the best of them.
Rarely did this happen without strong and persistent executive sponsorship. These leading companies invested in building scalable analytic capabilities—and in the communities of analysts and managers who comb through data, make decisions, and influence executives.
In addition to more efficient operations, this is also a promising path to identify new market opportunities, address competitive vulnerabilities, earn more loyal customers, and improve bottom-line business results. Or is it just that we are entrenched in the three Vs: volume of data, variety of data, and the velocity of data? With the barrage of data from such domains as cybersecurity, emergency management, healthcare, finance, transportation, and other domains, it becomes vitally important for organizations to make sense of this data and information on a timely and effective basis to improve the decisionmaking process.
Studies have shown that by , there will be a shortage of , to , business data analysts in the United States alone.
These analysts should know machine learning, advanced statistical techniques, and other predictive analytics to make sense of the various types of data—structured, unstructured, text, numbers, images, and others. This book is geared for filling this niche in terms of better understanding the organizational case studies, trends, issues, challenges, and techniques associated with big data and business analytics.

Понятия не имею. - Парень хмыкнул. - Меган все пыталась его кому-нибудь сплавить. - Она хотела его продать. - Не волнуйся, приятель, ей это не удалось. У тебя скверный вкус на ювелирные побрякушки.
Многие пункты даны не в числовой форме, - подбодрила людей Сьюзан. - Их мы можем проигнорировать. Уран природный элемент, плутоний - искусственный. Для урана используется ружейный детонатор, для плутония нужен взрыв. Это не числа, такие различия нас не касаются. - Работайте, - поторопил Фонтейн. На ВР последняя стена стала уже тоньше яичной скорлупы.
Беккер прищурился от внезапной вспышки яркого света. Это был тот самый парень, за которым он гнался от автобусной остановки. Беккер мрачно оглядел море красно-бело-синих причесок. - Что у них с волосами? - превозмогая боль, спросил он, показывая рукой на остальных пассажиров. - Они все… - Красно-бело-синие? - подсказал парень. Беккер кивнул, стараясь не смотреть на серебряную дужку в верхней губе парня.
Что вы имеете в виду.
Мотоцикл и такси с грохотом въехали в пустой ангар. Беккер лихорадочно осмотрел его в поисках укрытия, но задняя стена ангара, громадный щит из гофрированного металла, не имела ни дверей, ни окон. Такси было уже совсем рядом, и, бросив взгляд влево, Беккер увидел, что Халохот снова поднимает револьвер.
Решив, что никакой опасности нет, Стратмор запустил файл, минуя фильтры программы Сквозь строй. Сьюзан едва могла говорить. - Никакой Цифровой крепости не существует, - еле слышно пробормотала она под завывание сирены и, обессилев, склонилась над своим компьютером. Танкадо использовал наживку для дурачков… и АНБ ее проглотило.
Пустое пространство зала аэропорта открылось перед Беккером подобно бескрайней пустыне. Ноги несли его с такой быстротой, на какую, казалось ему, он не был способен. Когда он влетел во вращающуюся дверь, прозвучал еще один выстрел.
