An essay written around 160 AD, attributed to Lucian, a mock legal prosecution called The Consonants at Law - Sigma vs.The symbolism of the cross was connected not only to the letter chi but also to tau, the equivalent of the last letter in the Phoenician and Old Hebrew alphabets, and which was originally cruciform in shape see Cross of Tau.Its original sound value is a voiceless alveolar plosive, IPA /t/ In Biblical times, the taw was put on men to distinguish those who lamented sin, although newer versions of the Bible have replaced the ancient term taw with mark (Ezekiel 9:4) or signature (Job 31:35).In ancient times, tau was used as a symbol for life or resurrection, whereas the eighth letter of the Greek alphabet, theta, was considered the symbol of death.The symbol for tortuosity in hydrogeology.Torque, the rotational force in mechanics.Time constant (also relaxation time) of any system, such as an RC circuit.
In the physical sciences, tau is sometimes used as time variable, to avoid confusing t as temperature.Tau in astronomy is a measure of optical depth, or how much sunlight cannot penetrate the atmosphere.Tau, an elementary particle in particle physics.The lifetime of a spontaneous emission process.Translation in Euclidean geometry (although the Latin letter T is used more often).Torsion of a curve in differential geometry.Tau, the ratio of the circumference to the radius of a circle, which is equal to 2 π (6.28318.).Stopping time in stochastic processes.Kendall tau rank correlation coefficient in statistics.Golden ratio (1.618.), although φ ( phi) is more common.Divisor function in number theory, also denoted d or σ 0.Tau in biochemistry, a protein associated with microtubules and implicated in neurodegenerative diseases such as Alzheimer's disease, some forms of frontotemporal lobar degeneration, and chronic traumatic encephalopathy.The core variable in general tau theory.The dose interval in pharmacokinetics.The expressed period of the freerunning rhythm of an animal, i.e., the length of the daily cycle of an animal when kept in constant light or constant darkness.The lower-case letter τ is used as a symbol for: OCM activities aligned with project stagesBusiness environment & current state analysisBenefits planning.See also: Greek letters used in mathematics, science, and engineering § Ττ (tau) IT teamClient skillsUnderstand the business and how people will use the product/systemOvercome a determinist mindsetUnderstand basic OCM conceptsCommunicate IT concepts in plain languageUnderstand true nature of change impacts across complex systems People’s needs/interests are different from IT system needs/interestsOCM team Must observe scopeA balance of ‘hard’ (analysis, planning, risk assessment) skills as well as the ‘soft’ change skills (communication, engagement, empathy) Collaborators, doers & finishers Understand the business, the product/system and how people will use itBenefits focus Integrated approach A remarkable Project Manager who ‘gets it’Ĭlearly defined scope framed with change inputĬommonsense planning, thoughtful sequencing & scheduling of OCM & project activitiesīalance task focus & fluidity of momentum
