COMU1130 Chap.1 Data, Platforms and Stakeholders
Data, Platforms and Stakeholders
Data become socially consequential when institutions collect, classify and use them to make decisions. This chapter introduces platforms as programmable intermediaries that connect users, service providers, advertisers and public bodies while setting the rules of interaction.
It develops a layered method that links technical design, business models, public stories and stakeholder outcomes, giving students a reliable starting point for short applications and critical arguments. Begin by separating a service from its governance.
A marketplace may help two groups find each other, a feed may make culture discoverable and a civic app may coordinate participation, but the operator still chooses categories, defaults, verification rules and visibility. Those choices affect who can enter, what conduct becomes legible and whose contribution receives attention. The stakeholder map therefore records more than names.
For each group, identify its contribution, promised benefit, dependency, exposure to risk, voice in rule-setting and route of appeal. Next read the platform across four connected layers. The technical layer covers data fields, algorithms and interfaces. The economic layer covers ownership, pricing and value capture. The discursive layer covers the story told about freedom, efficiency or participation.
The institutional layer covers obligations such as access, fairness and accountability. A convincing explanation links at least two layers rather than treating code as an independent cause. Comparison strengthens the analysis: ask how the same activity was coordinated before the platform, what new benefit appears and which protection or informal practice may disappear.
Finish with a conditional judgement that names the mechanism and the affected public value. This method avoids both promotional description and automatic condemnation because it makes the allocation of opportunity, knowledge and decision power visible.

Data, Platforms and Stakeholders FAQ
Why is a platform more than a neutral tool?
A platform not only enables action. It selects categories, defines defaults, controls access to data and ranks visibility. Those choices organise opportunity and behaviour, so technical mediation also performs a governing role.
How should stakeholder interests be compared?
List what each group contributes, what benefit it expects, what dependency it acquires and what risk it carries. Keep users, complementors, advertisers, institutions and the operator separate before judging whose interest the rules prioritise.
What makes an application answer critical?
A critical answer names a mechanism, explains how it changes a stakeholder outcome and evaluates the public value at stake. Approval or concern without a causal link remains an opinion rather than analysis.
How can I move from a stakeholder list to an argument?
Treat the list as a map of unequal relationships rather than a cast of characters. For each actor, record what enters the platform, what returns, which rule the operator controls, whether the actor can influence that rule and what remedy exists when the outcome is disputed. Select one connection and express it as a causal chain.
For example, identity verification may improve trust while excluding people who cannot supply an accepted credential. Add the economic or institutional condition that makes this result possible, then compare it with the platform's public promise. The conclusion should state whose opportunity expands, whose dependency increases and which public value makes that distribution important.
This process turns the broad claim that stakeholders have different interests into a specific, evidence-ready judgement about governance.
Assessment move
Draw the stakeholder map from memory and add one platform-controlled rule to each connection. Practise writing one sentence for the benefit and one for the constraint. The chapter becomes useful across the course when you can move from a service description to the actors, rules, value flows and public consequences that produce it. Use three passes on a fresh case.
On the first pass, circle every actor and write what that actor contributes and receives. On the second, underline mechanism verbs such as verifies, classifies, ranks, prices, recommends and excludes. On the third, mark the technical, economic, discursive and institutional layer of each piece of evidence.
Convert the notes into a five-sentence paragraph: identify the platform claim, name the controlled rule, trace two stakeholder outcomes, state the public value and qualify the judgement. Test the paragraph by replacing vague nouns such as power or impact with a specific operation. Then write a counterfactual sentence explaining how the interaction would occur without the platform.
For quiz practice, give yourself six minutes and insist on one benefit as well as one constraint. For essay planning, expand the same map by adding evidence sources and an appeal or accountability question. Review mistakes by asking whether you collapsed different stakeholders, described an interface without its incentive, or reached a verdict before showing causation.
A sound answer should let another reader point to the exact rule that produces the consequence.
