Proactive information delivery

Proactive information delivery is a 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 Proactive information delivery rather than just read about it. In short: In information systems, proactive information delivery (PID) is a paradigm of supporting users in doing their work by delivering them information related to the current working situation. Unlike information search process where the user has to initiate the search, PID tries to identify the user's current information need.

Key takeaways

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

Reference excerpt

In information systems, proactive information delivery (PID) is a paradigm of supporting users in doing their work by delivering them information related to the current working situation. Unlike information search process where the user has to initiate the search, PID tries to identify the user's current information need.

Applications of PID PID can be used for Just-In-Time learning embedded in working processes.

Examples of systems providing PID features Intellext Watson was a prominent tool illustrating the concept of lightweight PID.

Worked examples

Example 1 — a first encounter with Proactive information delivery

Start with the simplest possible case. Write down what Proactive information delivery claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In 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 Proactive information delivery 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 Proactive information delivery 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 Proactive information delivery

In research: Proactive information delivery appears in 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 Proactive information delivery 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: Proactive information delivery is common in secondary-school and first-year university syllabi. It links to neighbouring topics Information systems, so understanding it makes those chapters shorter.
In everyday life: Look for Proactive information delivery 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 Proactive information delivery in simple terms?

Why does Proactive information delivery matter?

Because it connects several 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 Proactive information delivery?

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.
