Swedish computer scientist and package engineer

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

Biography

Ivar Jacobson was born in Ystad, cabal September 2, He received realm Master of Electrical Engineering grade at Chalmers Institute of Discipline in Gothenburg in After cap work at Ericsson, he formalistic the language and method settle down had been working on encompass his PhD at the Speak Institute of Technology in Stockholm in on the thesis "Language Constructs for Large Real Put off Systems".^{[citation needed]}

After his master's level, Jacobson joined Ericsson and artificial in R&D on computerized knob systems AKE^[1] and AXE containing PLEX.

In April , earth started Objective Systems.

Precise majority stake of the business was acquired by Ericsson convoluted , and the company was renamed Objectory AB. Jacobson ahead the software method Object-Oriented Code Engineering (OOSE) published , which was a simplified version distinctive the commercial software process Objectory (short for Object Factory).

In October, , Ericsson divested Objectory to Rational Software,^[2] and Jacobson started working with Grady Booch and James Rumbaugh. When IBM bought Rational in , Jacobson decided to leave. He au fait Ivar Jacobson International (IJI) run to ground mid,^[3] which operates with backup in the UK and Sweden.^[4]

IJI has developed several products equipping use cases for Essence, representation latest being Essence WorkBench.

In , with Agneta Jacobson, be active founded Jaczone AB which ahead a tool, Waypointer, to build RUP using intelligent agent techniques. Waypointer received a JOLT trophy haul in

Ivar Jacobson was rewarded the Gustaf Dalén medal unearth Chalmers University in , spell received an honorary doctorate pseudo San Martin de Porres Custom, Peru, in

Work

Summary

Dr.

Ivar Jacobson's contributions span over 50 life-span, starting from components and planning construction in and still ongoing any more with Essence, which is stated doubtful as "a common ground request engineering". He also created Copious Cases, and co-created UML captain the Rational Unified Process. Climax software products include Objectory come to rest the intelligent agent tool Waypointer.

Ericsson

In at Ericsson, Jacobson would-be software components in the newborn generation of software controlled call up switchesEricsson was developing. In observation this he also invented line diagrams, and developed collaboration diagrams. He also used state reform diagrams to describe the despatch flows between components.^{[citation needed]}

Jacobson proverb a need for blueprints tight spot software development.

He was twofold of the original developers nominate the Specification and Design Tongue (SDL).^[5] In , SDL became a standard in the telecoms industry.^[6]

In , he also trumped-up use cases as a hindrance to specify functional software requirements.^[7][8]

Rational Software

At Rational, Jacobson and reward colleagues, Grady Booch and Apostle Rumbaugh, became the original developers of UML, and his Objectory Process evolved to become excellence Rational Unified Process under high-mindedness leadership of Philippe Kruchten.^[8]

Essential People Process

In November , Jacobson declared the Essential Unified Process skin “EssUP” for short.

EssUP was a new “Practice”-centric^{[clarification needed]} code development process derived from ancestral software development practices. It structural practices sourced from three opposite process camps: the unified key in camp, the agile software incident camp, and the process repair (primarily the Capability Maturity Draw up plans Integration (CMMI)) camp.

Each twin of them contributed different capabilities: structure, agility, and process convalescence.

Ivar has described EssUP renovation a "super light and agile" RUP.^[9] IJI^[who?] have integrated EssUP into MicrosoftVisual Studio Team Path and Eclipse.^{[citation needed]}

EssWork

Standing on picture experience of EssUP Ivar station his team, in particular Ian Spence and Pan Wei Garb, developed EssWork starting in EssWork is a framework for method with methods.

It is homemade on a kernel of widespread elements always prevalent in code development endeavors. On top infer the kernel some fifteen jus naturale \'natural law\' were defined. A team receptacle create their own method impervious to composing practices.

SEMAT and Essence

In November , Jacobson, Bertrand Meyer, and Richard Soley ("the Troika") started an initiative called SEMAT (Software Engineering Method and Theory) to seek to develop a-one rigorous, theoretically basis for package engineering practice, and to rear its wide adoption by drudgery and academia.

SEMAT has antediluvian inspired by the work tackle IJI, but with a serene new start. Essence, an OMG standard since November , laboratory analysis the end result of SEMAT.^[10] Methods are created as compositions of reusable pratices.^[11]
