Follow-the-sun
Follow-the-sun (FTS), a sub-field of globally distributed software engineering (GDSE), is a type of global knowledge workflow designed in order to reduce the time to market, in which the knowledge product is owned and advanced by a production site in one time zone and handed off at the end of their work day to the next production site that is several time zones west to continue that work.Carmel, E., Dubinsky, Y., & Espinosa, A. (2009, January). Follow the sun software development: New perspectives, conceptual foundation, and exploratory field study. In System Sciences, 2009. HICSS'09. 42nd Hawaii International Conference on (pp. 1-9). IEEE.Carmel, E., Espinosa, J. A., & Dubinsky, Y. (2010). " Follow the Sun" Workflow in Global Software Development. Journal of Management Information Systems, 27(1), 17-38. Ideally, the work days in these time zones overlap such that when one site ends their day, the next one starts. FTS has the potential to significantly increase the total develop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agile Software Development
Agile software development is an umbrella term for approaches to software development, developing software that reflect the values and principles agreed upon by ''The Agile Alliance'', a group of 17 software practitioners, in 2001. As documented in their ''Manifesto for Agile Software Development'' the practitioners value: * Individuals and interactions over processes and tools * Working software over comprehensive documentation * Customer collaboration over contract negotiation * Responding to change over following a plan The practitioners cite inspiration from new practices at the time including extreme programming, Scrum (software development), scrum, dynamic systems development method, adaptive software development and being sympathetic to the need for an alternative to documentation driven, heavyweight software development processes. Many software development practices emerged from the agile mindset. These agile-based practices, sometimes called ''Agile'' (with a capital ...

Distributed Development
A distributed development project is a research and development (R&D) project that is done across multiple business worksites or locations. It is a form of R&D where the project members may not see each other face to face, but they are all working collaboratively toward the outcome of the project. Often this is done through email, the Internet and other forms of quick long-distance communication.Mitch Kapor, How to Build a Successful Company', lecture to Stanford University entrepreneurship students, 2008-01-16. Distributed development was largely pioneered by the open-source software community. It is different from outsourcing because all of the organizations are working together on an equal level, instead of one organization subcontracting the work to another. It is similar to a virtual team but with a research element. Characteristics of distributed development Developers are distributed across multiple locations and work on the same project or product. The reasons for the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Time To Market
In commerce, time to market (TTM) is the length of time it takes from a product being conceived until its being available for sale. The reason that time to market is so important is that being late erodes the addressable market into which producers have to sell their product. A common assumption is that TTM matters most for first-of-a-kind products, but actually a late product launch in any industry can negatively impact revenues—from reducing the window of opportunity to generate revenues to causing the product to become obsolete faster. Measuring TTM There are no standards for measuring TTM, and measured values can vary greatly. First, there is great variation in how different organizations define the start of the period. For example, in the automotive industry the development period starts when the product concept is approved. Other organizations realize that little will happen until the project is staffed, which can take a long time after approval if developers are tied u ...

24/7 Service
In commerce and industry, 24/7 or 24-7 service (usually pronounced "twenty-four seven") is Service (economics), service that is available at any time and usually, every day. An alternate orthography for the numerical part includes 24×7 (usually pronounced "twenty-four by seven"). The numerals stand for "24 hours a day, 7 days a week". Less commonly used, 24/7/52 (adding "52 weeks") and 24/7/365 service (adding "365 days") make it clear that service is available every day of the year. Synonyms include around-the-clock service (with/without hyphens) and all day every day, especially in British English, and nonstop service, but the latter can also refer to other things, such as public transport services which go between two stations without stopping. The ''Oxford English Dictionary'' (OED) defines the term as "twenty-four hours a day, seven days a week; constantly". It lists its first reference to 24/7 to be from a 1983 story in the US magazine ''Sports Illustrated'' in which Lou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waterfall Model
The waterfall model is a breakdown of developmental activities into linear sequential phases, meaning that each phase is passed down onto each other, where each phase depends on the deliverables of the previous one and corresponds to a specialization of tasks. This approach is typical for certain areas of engineering design. In software development, it tends to be among the less iterative and flexible approaches, as progress flows in largely one direction (downwards like a waterfall) through the phases of conception, initiation, analysis, design, construction, testing, deployment, and maintenance. The waterfall model is the earliest systems development life cycle ( SDLC) approach used in software development. When it was first adopted, there were no recognized alternatives for knowledge-based creative work. History The first known presentation describing the use of such phases in software engineering was held by Herbert D. Benington at the Symposium on Advanced Programming ...

Datacenter
A data center is a building, a dedicated space within a building, or a group of buildings used to house computer systems and associated components, such as telecommunications and storage systems. Since IT operations are crucial for business continuity, it generally includes redundant or backup components and infrastructure for power supply, data communication connections, environmental controls (e.g., air conditioning, fire suppression), and various security devices. A large data center is an industrial-scale operation using as much electricity as a medium town. Estimated global data center electricity consumption in 2022 was 240–340 TWh, or roughly 1–1.3% of global electricity demand. This excludes energy used for cryptocurrency mining, which was estimated to be around 110 TWh in 2022, or another 0.4% of global electricity demand. The IEA projects that data center electric use could double between 2022 and 2026. High demand for electricity from data centers, includ ...

Peak Demand
Peak demand on an electrical grid is the highest electrical power demand that has occurred over a specified time period (Gönen 2008). Peak demand is typically characterized as annual, daily or seasonal and has the unit of power. Peak demand, peak load or on-peak are terms used in energy demand management describing a period in which electrical power is expected to be provided for a sustained period at a significantly higher than average supply level. Peak demand fluctuations may occur on daily, monthly, seasonal and yearly cycles. For an electric utility company, the actual point of peak demand is a single half-hour or hourly period which represents the highest point of customer consumption of electricity. At this time there is a combination of office, domestic demand and at some times of the year, the fall of darkness. Some utilities will charge customers based on their individual peak demand. The highest demand during each month or even a single 15 to 30 minute period of high ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Change-of-shift Report
In healthcare, a change-of-shift report is a meeting between healthcare providers at the change of shift in which vital information about and responsibility for the patient is provided from the off-going provider to the on-coming provider (Groves, Manges, Scott-Cawiezell, 2016). Other names for change-of-shift report include handoff, shift report, handover, or sign-out. Change-of-shift report is key to inpatient care because healthcare providers (nurses, physicians, nursing assistants etc.) are essential to providing around the clock care. Nursing change-of-shift report During report, the outgoing nurses discuss with the oncoming nurses the condition of each patient and any changes that have occurred to the patient during the shift. The purpose is not to cover all details recorded in the patient's medical record, but to summarize individual patient progress. The content of the report often depends on the local organization. Issues with report While report is necessary in order t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
