Portfolio Management : Delivering on Strategy
Portfolio management is becoming the ‘must have’ for organizations to prosper and survive in this decade and beyond.No longer can the organizational focus be one of following best and repeatable practices as resource limitations mean only those programs, projects, and operational work that add business value can and should be pursued.Executives are focusing on strategic ability and managing complexity, which can only be done through a disciplined portfolio process in ensuring the best mix of programs, projects, and operational work is under way.In turn, the portfolio is constantly in flux as difficult decisions are made if a project, for example, is no longer contributing to business value and providing benefits and should be terminated to reallocate resources to one of higher priority.Commitment to this difficult approach is necessary at all levels, and communication is required so everyone knows how their work contributes to the organization’s strategic goals and objectives. Portfolio Management: Delivering on Strategy, Second Edition focuses on the benefits of portfolio management to the organization.Its goal is to provide senior executives a view on how portfolio management can deliver organizational strategy.The emphasis is on the specific aspects within the portfolio management discipline and how each aspect should be managed from a business perspective and not necessarily from a portfolio management perspective.Highlights of the book include:Agile portfolio management Delivering organizational value Portfolio management and uncertainty Portfolio governance Marketing a portfolio Portfolio management success Starting with a review of the project portfolio concept and its development, this book is a reference for executives and practitioners in the field, as well as a students and researchers studying portfolio management.

How do you calculate variability?
Variability can be calculated using measures such as range, variance, and standard deviation. The range is the difference between the highest and lowest values in a dataset. Variance is the average of the squared differences from the mean, while the standard deviation is the square root of the variance. These measures help to quantify the spread or dispersion of data points in a dataset, providing insight into the variability of the data.

What is genetic variability/diversity?
Genetic variability/diversity refers to the differences in genetic makeup among individuals within a population or species. It is essential for the survival and adaptation of a species to changing environments. Genetic diversity allows for the evolution of new traits and adaptations, increasing the chances of a population's survival in the face of environmental challenges and diseases. Maintaining genetic diversity is crucial for the long-term health and sustainability of a population or species.
-
How does infinite variability work?
Infinite variability refers to the concept that there are an infinite number of possible variations or combinations within a given system or set of elements. This means that there is no limit to the potential diversity or range of outcomes that can arise. In practical terms, this means that within any given system or process, there is an endless array of potential configurations, choices, and results. This concept is important in fields such as biology, genetics, and technology, where the potential for variation and diversity is crucial to understanding and harnessing the complexity of natural and artificial systems.

What is genetic variability and diversity?
Genetic variability refers to the differences in genetic makeup among individuals within a population or species. It is essential for adaptation and evolution as it allows for a range of traits and characteristics to be present within a population. Genetic diversity, on the other hand, refers to the total number of different genetic characteristics in a population. It is important for the long-term survival of a species as it increases the chances of individuals being able to adapt to changing environments and resist diseases.

Variability and Consistency in Early Language Learning : The Wordbank Project
The Wordbank Project examines variability and consistency in children's language learning across different languages and cultures, drawing on Wordbank, an open database with data from more than 75,000 children and twenty-nine languages or dialects.This big data approach makes the book the most comprehensive cross-linguistic analysis to date of early language learning.Moreover, its data-driven picture of which aspects of language learning are consistent across languages suggests constraints on the nature of children's language learning mechanisms.The book provides both a theoretical framework for scholars of language learning, language, and human cognition, and a resource for future research.

What is recombination and genetic variability?
Recombination is the process by which genetic material is exchanged between two similar molecules of DNA, resulting in new combinations of genes. This process occurs during meiosis, the cell division that produces gametes (sperm and egg cells). Genetic variability refers to the diversity of genetic material within a population, which is influenced by factors such as recombination, mutations, and gene flow. Recombination plays a key role in generating genetic variability by creating new combinations of genes, which can lead to increased diversity and adaptation within a population.

What is the genetic variability in cheetahs?
Cheetahs have very low genetic variability compared to other big cats, with estimates suggesting that they have lost around 90% of their genetic diversity. This is due to a population bottleneck that occurred around 10,000 years ago, reducing their numbers to a small population with limited genetic variation. Low genetic variability can make cheetahs more susceptible to diseases and environmental changes, posing a threat to their long-term survival as a species. Conservation efforts are being made to address this issue and increase genetic diversity in cheetah populations.

How can I improve my heart rate variability (HRV)?
To improve your heart rate variability (HRV), you can focus on reducing stress and improving your overall health. Engaging in regular physical activity, practicing relaxation techniques such as deep breathing, meditation, and yoga, getting enough sleep, and maintaining a healthy diet can all contribute to improving HRV. Additionally, managing stress through activities like mindfulness and spending time in nature can also help improve HRV. It's important to consult with a healthcare professional before making any significant changes to your lifestyle or starting a new exercise regimen.

What does variability in evolution mean in simple terms?
Variability in evolution refers to the differences that exist among individuals within a population. This variation can be caused by genetic mutations, genetic recombination, and environmental factors. It is essential for the process of natural selection, as it allows for some individuals to be better suited to their environment and more likely to survive and reproduce, passing on their advantageous traits to future generations. Overall, variability in evolution is a key component that drives the diversity of life on Earth.
