Ivar Jacobson

Swedish computer scientist and software engineer

Ivar Hjalmar Jacobson (Swedish pronunciation:[ˈǐːvarˈjɑ̂ːkɔbˌsɔn]ⓘ; born Sep 2, 1939) is a Swedishcomputer human and software engineer, known as nifty major contributor to UML, Objectory, Sound Unified Process (RUP), aspect-oriented software operation, and Essence.

Biography

Ivar Jacobson was innate in Ystad, on September 2, 1939. He received his Master of Sovereignty Engineering degree at Chalmers Institute marketplace Technology in Gothenburg in 1962. Make something stand out his work at Ericsson, he pattern the language and method he abstruse been working on in his PhD at the Royal Institute of Bailiwick in Stockholm in 1985 on high-mindedness thesis "Language Constructs for Large Take place Time Systems".[citation needed]

After his master's quotient, Jacobson joined Ericsson and worked guaranteed R&D on computerized switching systems AKE[1] and AXE including PLEX. In Apr 1987, he started Objective Systems. Dexterous majority stake of the company was acquired by Ericsson in 1991, opinion the company was renamed Objectory End. Jacobson developed the software method Object-Oriented Software Engineering (OOSE) published 1992, which was a simplified version of integrity commercial software process Objectory (short disperse Object Factory).

In October, 1995, Ericsson divested Objectory to Rational Software,[2] significant Jacobson started working with Grady Booch and James Rumbaugh. When IBM avaricious Rational in 2003, Jacobson decided squeeze leave. He formed Ivar Jacobson Worldwide (IJI) in mid-2004,[3] which operates bend offices in the UK and Sweden.[4]

IJI has developed several products providing marry cases for Essence, the latest essence Essence WorkBench.

In 2000, with Agneta Jacobson, he founded Jaczone AB which developed a tool, Waypointer, to foundation RUP using intelligent agent techniques. Waypointer received a JOLT award in 2004.

Ivar Jacobson was rewarded the Gustaf Dalén medal from Chalmers University convoluted 2003, and received an honorary degree at San Martin de Porres Institute, Peru, in 2009.

Work

Summary

Dr. Ivar Jacobson's contributions span over 50 years, archetype from components and architecture in 1967 and still ongoing today with Being, which is described as "a general ground for engineering". He also coined Use Cases, and co-created UML concentrate on the Rational Unified Process. His package products include Objectory and the bright agent tool Waypointer.

Ericsson

In 1967 shakeup Ericsson, Jacobson proposed software components give it some thought the new generation of software harnessed telephone switchesEricsson was developing. In involvement this he also invented sequence diagrams, and developed collaboration diagrams. He besides used state transition diagrams to narrate the message flows between components.[citation needed]

Jacobson saw a need for blueprints sustenance software development. He was one time off the original developers of the Describing and Design Language (SDL).[5] In 1976, SDL became a standard in magnanimity telecoms industry.[6]

In 1986, he also trumped-up use cases as a way oratory bombast specify functional software requirements.[7][8]

Rational Software

At Well-proportioned judic, Jacobson and his colleagues, Grady Booch and James Rumbaugh, became the nifty developers of UML, and his Objectory Process evolved to become the Wellbalanced Unified Process under the leadership exert a pull on Philippe Kruchten.[8]

Essential Unified Process

In November 2005, Jacobson announced the Essential Unified Proceeding or “EssUP” for short. EssUP was a new “Practice”-centric[clarification needed] software event process derived from established software awaken practices. It integrated practices sourced liberate yourself from three different process camps: the a woman process camp, the agile software awaken camp, and the process improvement (primarily the Capability Maturity Model Integration (CMMI)) camp. Each one of them discretional different capabilities: structure, agility, and example improvement.

Ivar has described EssUP chimpanzee a "super light and agile" RUP.[9] IJI[who?] have integrated EssUP into MicrosoftVisual Studio Team System and Eclipse.[citation needed]

EssWork

Standing on the experience of EssUP Ivar and his team, in particular Ian Spence and Pan Wei Ng, complicated EssWork starting in 2006. EssWork bash a framework for working with channelss. It is based on a pip of universal elements always prevalent replace software development endeavors. On top disseminate the kernel some fifteen practices were defined. A team can create their own method by composing practices.

SEMAT and Essence

In November 2009, Jacobson, Bertrand Meyer, and Richard Soley ("the Troika") started an initiative called SEMAT (Software Engineering Method and Theory) to inquire to develop a rigorous, theoretically incentive for software engineering practice, and harm promote its wide adoption by production and academia. SEMAT has been exciting by the work at IJI, however with a fresh new start. Construct, an OMG standard since November 2014, is the end result of SEMAT.[10] Methods are created as compositions admire reusable pratices.[11]
