Project charter definition

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
“Part of project planning is to create a project charter, which defines the project. The project charter is the agreement between the business and IT for [developing the BI application]. If any component of the project charter changes, the entire project has to be reevaluated and the entire project charter has to be renegotiated. — Shaku Atre” –

Today’s WhatIs.com Word of the Day is project charter.  It’s one of those project management terms that can be used to describe documents with very different structures depending on the business culture, but two things remains consistent whether it’s a one page sign-off from the CEO or a twenty-page document put together by the project management office (PMO) — (1) the charter is the written agreement that authorizes a project and (2) it’s not a living document.

Registry key definition

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
“When analyzing a compromised Windows system, investigators and system administrators can glean enormously useful information about attackers’ actions by looking through the Windows registry, a hierarchical database storing tens of thousands of settings on a Windows box.”Ed Skoudis

Today’s WhatIs.com Word of the Day is registry key. In the Windows 98, CE, NT, and 2000 operating systems, a registry key is an organizational unit in the Windows registry. Registry keys are the HKEY folders you see when you run the line command “regedit.”  Treat them with respect.

Tumblr definition

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
“A common critique of Tumblr is its resistance to monetization.” – Delaney Rebernik

Today’s Word of the Day is Tumblr, a microblogging site that claims it retains members better than Twitter. It’s hip, it’s young and it’s something marketers haven’t quite figured out how to use.

Five whys definition

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
” In ‘five whys,’ you focus on getting to the root cause of an issue by repeatedly asking ‘why’ to drill deeper toward the underlying cause. It’s important to note that this is ‘five whys,’ NOT ‘five whos.’Zach Nies

Today’s WhatIs.com Word of the Day is 5 Whys, a team exercise for identifying the root cause of a problem. 5 Whys was originally used in manufacturing to help management identify why equipment failed. It’s used in Six Sigma during DMAIC exercises and in Agile retrospectives.

VMware’s Horizon Mobile Manager definition

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
“VMware said running two separate environments on a mobile phone doesn’t require excess resources and uses up to no more than 1% extra phone battery life.”Bridget Botelho

Today’s WhatIs.com Word of the Day is VMware Horizon Mobile Manager, an extension of VMWare App Manager. VMware says it will come in two flavors, one for iOS (with app wrapping) and one for Android (that essentially adds a second ‘desktop’ to the phone). Critics are already complaining that two flavors are impractical.

Interrupt Latency

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
“Latency is reported in two different ways: interrupt and scheduling…Interrupt latency is the measurement of system’s response-time to an interrupt…Scheduling latency is usually a measure of performance for the RTOS thread scheduler.”Faheem Sheikh and Dan Driscoll

Today’s WhatIs.com Word of the Day is interrupt latency.  It’s a term you might have heard vendors quoting when they brag about “zero latency.” Zero latency is more accurately defined as the time added by a realt-time operating system (RTOS) to the regular processing of an interrupt.

DMAIC (define, measure, analyze, improve control) definition

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
“Along the way, I fear we’ve lost sight of the powerful principle that underlies Six Sigma: To improve any process, start by defining a simple standard or benchmark. Then measure variation from the standard and investigate the reason for variation. Apply what we learn to improve the process.” — Niel Nickolaisen

Today’s WhatIs.com Word of the Day is DMAIC, the Six Sigma tool for improving a process. DMAIC (pronounced de-may-ick) is often associated with a big problem or a process that —  like a runaway train — has gone off the rails, but it can also be useful for fine-tuning a process that already works reasonably well. The letters in DMAIC stand for define, measure, analyze, improve, control.

Reverse electrovibration (virtual touch) definition

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
Disney researchers have discovered an approach to fool our sense of touch into believing that an object has a texture far different than what it actually is. It relies on reverse electrovibration, a new technique that creates the illusion of a range of textures as the user’s fingers sweep across a surface, without the need for actuators.” — Brian Dodson

Today’s WhatIs.com Word of the Day is reverse electrovibration. The most highly anticipated application of reverse electrovibration is one allowing a person to sense the texture of a distant object on the touch screen of a computer or tablet device.

Goobuntu definition

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
“Just go get Ubuntu and run it and you’ve got Goobuntu. The only thing we’re adding are special tools to access Google specific resources that our engineers need.” – Thomas Bushnell

Today’s WhatIs.com Word of the Day is Goobuntu, the default workstation OS that Google employees use.

reference architecture definition

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
“…Building an enterprise cloud based on a reference architecture without considerable work defining business objectives and system requirements would only be an exercise in frustration. ” – Beth Cohen

Today’s WhatIs.com Word of the Day is reference architecture.  In project management, it’s a resource comprised of documentation from past projects. The idea is that you can “go shopping” for ideas of how something was built in the past and either copy it, avoid it or adopt it.

Vendors are using the term today to sell their converged infrastructure products, providing potential customers with a “reference architecture” for possible ways to buy/use their products. In a worst-case scenario,  you can simply substitute the words “hypothetical implementation” for the much more real “reference architecture.”
