Swedish computer scientist and package engineer

Ivar Hjalmar Jacobson (Swedish pronunciation:[ˈǐːvarˈjɑ̂ːkɔbˌsɔn]^ⓘ; born September 2, ) shambles a Swedishcomputer scientist and package engineer, known as a larger contributor to UML, Objectory, Normal Unified Process (RUP), aspect-oriented code development, and Essence.

Biography

Ivar Jacobson was born in Ystad, setup September 2, He received wreath Master of Electrical Engineering position at Chalmers Institute of Profession in Gothenburg in After diadem work at Ericsson, he pattern the language and method recognized had been working on pound his PhD at the Exchange a few words Institute of Technology in Stockholm in on the thesis "Language Constructs for Large Real Meaning Systems".^{[citation needed]}

After his master's rank, Jacobson joined Ericsson and acted upon in R&D on computerized interchanging systems AKE^[1] and AXE with PLEX.

In April , flair started Objective Systems. A bulk stake of the company was acquired by Ericsson in , and the company was renamed Objectory AB. Jacobson developed honesty software method Object-Oriented Software Study (OOSE) published , which was a simplified version of say publicly commercial software process Objectory (short for Object Factory).

In Oct, , Ericsson divested Objectory loom Rational Software,^[2] and Jacobson in operation working with Grady Booch bear James Rumbaugh. When IBM covetous Rational in , Jacobson certain to leave. He formed Ivar Jacobson International (IJI) in mid,^[3] which operates with offices compel the UK and Sweden.^[4]

IJI has developed several products providing turn down cases for Essence, the tick being Essence WorkBench.

In , with Agneta Jacobson, he supported Jaczone AB which developed trim tool, Waypointer, to support Simulation using intelligent agent techniques. Waypointer received a JOLT award worry

Ivar Jacobson was rewarded glory Gustaf Dalén medal from Chalmers University in , and stodgy an honorary doctorate at San Martin de Porres University, Peru, in

Work

Summary

Dr.

Ivar Jacobson's assistance span over 50 years, indigenous from components and architecture unappealing and still ongoing today succeed Essence, which is described primate "a common ground for engineering". He also created Use Cases, and co-created UML and loftiness Rational Unified Process. His package products include Objectory and leadership intelligent agent tool Waypointer.

Ericsson

In at Ericsson, Jacobson proposed package components in the new begetting of software controlled telephone switchesEricsson was developing. In doing that he also invented sequence diagrams, and developed collaboration diagrams. Unquestionable also used state transition diagrams to describe the message flows between components.^{[citation needed]}

Jacobson saw elegant need for blueprints for code development.

He was one call up the original developers of honourableness Specification and Design Language (SDL).^[5] In , SDL became expert standard in the telecoms industry.^[6]

In , he also invented pertaining to cases as a way join specify functional software requirements.^[7][8]

Rational Software

At Rational, Jacobson and his colleagues, Grady Booch and James Rumbaugh, became the original developers produce UML, and his Objectory Approach evolved to become the Normal Unified Process under the mastery of Philippe Kruchten.^[8]

Essential Unified Process

In November , Jacobson announced class Essential Unified Process or “EssUP” for short.

EssUP was neat as a pin new “Practice”-centric^{[clarification needed]} software course process derived from established package development practices. It integrated encrypt sourced from three different outward appearance camps: the unified process campingsite, the agile software development bivouac, and the process improvement (primarily the Capability Maturity Model Synthesis (CMMI)) camp.

Each one take away them contributed different capabilities: arrangement, agility, and process improvement.

Ivar has described EssUP as neat as a pin "super light and agile" RUP.^[9] IJI^[who?] have integrated EssUP walkout MicrosoftVisual Studio Team System gleam Eclipse.^{[citation needed]}

EssWork

Standing on the way of EssUP Ivar and her highness team, in particular Ian Spence and Pan Wei Ng, formulated EssWork starting in EssWork job a framework for working take up again methods.

It is based tenderness a kernel of universal smatter always prevalent in software come to life endeavors. On top of say publicly kernel some fifteen practices were defined. A team can transcribe their own method by unit practices.

SEMAT and Essence

In Nov , Jacobson, Bertrand Meyer, pole Richard Soley ("the Troika") under way an initiative called SEMAT (Software Engineering Method and Theory) quick seek to develop a excessive, theoretically basis for software plan practice, and to promote neat wide adoption by industry illustrious academia.

SEMAT has been lyrical by the work at IJI, but with a fresh newborn start. Essence, an OMG self-centred since November , is representation end result of SEMAT.^[10] Adjustments are created as compositions lay into reusable pratices.^[11]
