SIEN6004 Chap.6 Value Chains, Platforms and Collaboration
Value Chains, Platforms and Collaboration
This chapter distinguishes sequential value-chain analysis from platform-ecosystem analysis. A value chain locates activities, hand-offs, added value and control. A platform core sets interfaces and governance that connect complementors with users. Switching costs, co-specialisation, data and participation rules determine whether collaboration remains productive.
A final section shows how interdisciplinary teams build translation structures around a shared problem.

Value Chains, Platforms and Collaboration FAQ
How does a platform differ from a value chain?
A chain follows sequential activities and hand-offs, while a platform mediates repeated interaction between complements and user groups through a shared core with participation rules. Use both maps only when both decisions genuinely matter.
Why do switching costs matter?
They can support durable participation but may also lock users or partners into unfavourable relationships, reduce resilience and weaken bargaining when alternatives become costly. Governance should distinguish commitment from harmful lock-in.
What makes interdisciplinary collaboration work?
A shared outcome, explicit contribution interfaces, common evidence, translation structures and clear ownership of specialist and collective decisions are all needed for productive interdisciplinary work. Integration is visible when one discipline changes another assumption.
How can platform governance be stress-tested?
Run a failure drill in which a quality incident, complementor exit or data dispute occurs. For each event, identify the rule, interface and decision owner that should respond, plus the effect on users and partners. Ask whether the design detects the problem early enough and whether portability or an alternative supplier reduces harm.
Conclude by naming one rule that should remain stable and one that should adapt as participation, evidence or risk changes.
Assessment move
Choose the map that matches the decision. Use a value chain for sequential activities, hand-offs, added value and control; use a platform map for repeated interaction among complements and user groups through a governed core. Practise redrawing one case both ways and explain what each view reveals or hides.
In chain analysis, mark where knowledge enters, where failures can occur, who controls customer access and which activities are difficult to replace. In platform analysis, specify entry rules, interfaces, pricing, data rights, quality controls, dispute processes and portability. Study switching costs and co-specialisation as double-edged: they can support committed investment while creating dependence and fragility.
Test resilience by removing one major complementor and asking whether modular interfaces or alternative suppliers allow the system to continue. For interdisciplinary collaboration, define the shared problem, contributions and decision criteria before arranging meetings. Use prototypes, canvases or evidence tables as boundary objects that let specialists change one another's assumptions.
Record those changes as evidence of integration. Before the theory quiz, state why the selected map fits the question. Before the group report, connect governance and chain position to the Business Model Canvas, especially partner incentives, activities, customer relationships, cost and revenue sharing.
Develop map selection by taking one digital venture and drawing its value chain, platform ecosystem and interdisciplinary project interface separately. The chain should show activities, hand-offs, contribution, failure risk and control from research through service. The platform map should show the core, complementors, user groups, interfaces and governance rules.
The collaboration map should show specialist contributions, shared evidence and decision ownership. Compare the three and write which management question each answers. Analyse switching costs from both sides: they can support commitment and co-specialised investment, but they can also weaken bargaining and resilience. Test the platform by removing a major complementor, changing an entry rule and making user records portable.
Observe how each change affects trust, participation and capture. For the value chain, identify where knowledge and customer contact concentrate and whether the project occupies a replaceable activity. Before the quiz, require every platform answer to name the core and at least two governance choices. Before the group report, link interface rules and chain position to partners, activities, relationships, costs and revenue.
During team collaboration, record which specialist insight changes another assumption; attendance alone is not integration. Use an early prototype or shared decision table to expose dependencies while changes remain possible. End revision by explaining when tight control improves quality and when it starves the system of complementary innovation.
