Dependencies refer to the relationships between activities, deliverables, projects, or external factors where one element relies on another to progress or complete. In a programme context, dependencies are more complex than in individual projects because they span multiple projects and business-as-usual operations. MSP identifies several types: intra-programme dependencies (between projects within the programme), inter-programme dependencies (between different programmes), and external dependencies (reliance on factors outside the programme's control, such as suppliers, regulations, or other organisational initiatives). Managing dependencies effectively is essential to maintaining the programme's schedule and realising benefits, as unmanaged dependencies can cause delays and undermine the Justification through eroded value.
Interfaces represent the points of interaction or connection between the programme and its projects, other programmes, business operations, and stakeholders. Interfaces require careful coordination to ensure smooth handovers, consistent communication, and alignment of expectations. They are particularly important where programme outputs transition into operational use, linking to benefits realisation.
Within the Structure Theme, defining governance and delivery arrangements helps map and control these dependencies and interfaces, ensuring roles, responsibilities, and coordination mechanisms are clear. The Justification Theme is supported because well-managed dependencies protect the business case and expected value by preventing disruptions. The Knowledge Theme contributes by ensuring information about dependencies and interfaces is captured, shared, and used for informed decision-making, supporting lessons learned and effective communication.
Ultimately, understanding and actively managing dependencies and interfaces enables the programme to maintain alignment, mitigate risks, coordinate delivery across complex environments, and sustain the strategic justification, ensuring the programme achieves its intended outcomes and benefits in a controlled and integrated manner throughout its lifecycle.
Dependencies and Interfaces in MSP
Introduction In the context of the MSP (Managing Successful Programmes) framework, understanding Dependencies and Interfaces is essential for anyone preparing for the Foundation examination. This guide explains why these concepts matter, what they are, how they work, and how to answer exam questions about them effectively.
Why Dependencies and Interfaces Are Important A programme is not a single, isolated piece of work. It is made up of multiple projects, business-as-usual activities, and external influences that must all come together to deliver the desired outcomes and benefits. Dependencies and interfaces are the connective tissue that holds these elements together.
If dependencies are not identified and managed, one project's delay can ripple across the entire programme, delaying benefits realisation and undermining the business case. Managing these relationships ensures coordination, reduces risk, and keeps the programme aligned with its strategic objectives.
What Are Dependencies? A dependency is a relationship where the progress or completion of one element relies on another. In MSP, dependencies typically fall into these categories:
1. Internal dependencies – relationships between projects within the programme, for example, Project B cannot start until Project A delivers a specific output. 2. Intra-project dependencies – dependencies that exist inside a single project (usually managed at project level). 3. Inter-programme dependencies – dependencies between separate programmes. 4. External dependencies – reliance on things outside the programme's control, such as legislation, suppliers, or other organisational initiatives.
Dependencies can also be described by their direction: whether the programme depends on something (an inbound dependency) or whether something depends on the programme (an outbound dependency).
What Are Interfaces? An interface is the point of interaction or connection between the programme and other entities, such as other programmes, projects, business operations, or external organisations. Interfaces define how information, deliverables, and resources are exchanged. Managing interfaces effectively ensures smooth handovers and clear communication across boundaries.
How They Work Within MSP Dependencies and interfaces are managed as part of the programme's planning and control activities. Key mechanisms include:
Dependency logs/registers: A record of all identified dependencies, their nature, owner, and status. The Programme Plan: Consolidates project timelines and highlights where dependencies must be coordinated. Governance and control: The Programme Manager monitors dependencies, while the Business Change Manager focuses on interfaces with business operations. Risk management: Dependencies are a common source of risk, so they are closely linked with the risk management approach.
By continuously tracking these relationships, the programme can respond to changes, re-plan where necessary, and protect the delivery of outcomes and benefits.
How to Answer Exam Questions Foundation-level questions on Dependencies and Interfaces are usually multiple choice and test your ability to recall definitions and recognise examples. Focus on:
- Distinguishing between the types of dependencies (internal, external, inter-programme). - Recognising the difference between a dependency and an interface. - Understanding who is responsible for managing them within programme governance. - Identifying how dependencies relate to planning, control, and risk.
Exam Tips: Answering Questions on Dependencies and Interfaces
1. Read each question carefully and identify whether it is asking about a type, a definition, or a responsibility. 2. Watch for keywords like external, internal, and inter-programme – these often signal which category of dependency is being tested. 3. Remember that dependencies are about reliance, while interfaces are about points of connection or interaction. 4. Eliminate obviously wrong options first, then choose the answer most aligned with MSP terminology. 5. Do not overthink Foundation questions – they test recall and understanding, not application or judgement. 6. Link dependencies to risk and planning when a question asks about their significance to the programme.
Summary Dependencies and Interfaces ensure that the many moving parts of a programme work together to deliver its intended benefits. For the exam, master the definitions, recognise the types, and understand how they connect to planning, control, and risk. With clear knowledge of these fundamentals, you will confidently handle any related question.
