Telelogic

Telelogic is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Telelogic rather than just read about it. In short: Telelogic AB was a software business headquartered in Malmö, Sweden. Telelogic was founded in 1983 as a research and development arm of Televerket, the Swedish Department of Telecommunications (now part of TeliaSonera).

Key takeaways

Telelogic belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Telelogic to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Telelogic from memory before moving on to harder problems.

Reference excerpt

Telelogic AB was a software business headquartered in Malmö, Sweden. Telelogic was founded in 1983 as a research and development arm of Televerket, the Swedish Department of Telecommunications (now part of TeliaSonera). It was later acquired by IBM Rational, and exists under the IBM software group. Telelogic had operations in 22 countries and had been publicly traded since 1999. CEO and President in 2001 was Anders Lidbeck. On June 11, 2007, IBM announced that it had made a cash offer to acquire Telelogic. On August 29, 2007, the European Union opened an investigation into the acquisition. On March 5, 2008, European regulators approved the acquisition of Telelogic by the Swedish IBM subsidiary Watchtower AB. On April 28, 2008, IBM completed its purchase of Telelogic.

Former Products Focal Point [1] — System for management of product and project portfolios. DOORS — Requirements tracking tool. System Architect — Enterprise Architecture and Business Architecture modeling tool. Tau — SDL and UML modeling tool. Synergy — Task-based version control and configuration management system. Rhapsody — Systems engineering and executable UML modeling tool. DocExpress — Technical documentation tool, discontinued after the acquisition and superseded by Publishing Engine. Publishing Engine — Technical documentation tool All of these products have been continued under IBM's Rational Software division in the systems engineering and Product lifecycle management (PLM) "solutions" software line. IBM sold System Architect, Focal Point and several other software products to UNICOM Global in 2016.

Acquisitions Telelogic acquired the following companies between 1999 and 2007:

Worked examples

Example 1 — a first encounter with Telelogic

Start with the simplest possible case. Write down what Telelogic claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Telelogic before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Telelogic ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Telelogic

In research: Telelogic appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Telelogic in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Telelogic is common in secondary-school and first-year university syllabi. It links to neighbouring topics Companies based in Malmö, Companies established in 1983, Defunct software companies of Sweden, so understanding it makes those chapters shorter.
In everyday life: Look for Telelogic outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Telelogic in simple terms?

Why does Telelogic matter?

Because it connects several computer science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Telelogic?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
