Demystifying Project Assumptions: A Comprehensive Overview and 30 Examples
Assumptions are a critical part of any project plan. But what exactly are project assumptions and what are some examples? In this comprehensive guide I’ll explain what project assumptions are provide 30 examples, and discuss strategies for managing them effectively.
What Are Project Assumptions?
Project assumptions refer to factors that are considered true, real, or certain for planning purposes, despite lacking proof Assumptions are made based on past experience, precedent, and general knowledge about how projects operate.
Some key characteristics
- Assumptions address uncertainties and risks in projects
- They are deemed true even without concrete evidence
- Used for planning when details are unknown
- Impacted if proven to be incorrect
Project managers make reasonable assumptions to fill in gaps in information. But recognizing the risk of invalid assumptions is crucial. When incorrect, they can lead to issues like:
- Unrealistic budgets or timelines
- Inadequate resources
- Poor alignment with objectives
- Requirement changes
Proactively identifying and documenting assumptions allows risks to be handled appropriately. Now let’s look at some examples.
30 Examples of Common Project Assumptions
Project assumptions generally fall into a few key categories:
Resource Assumptions
These relate to the personnel, equipment, materials, and other elements needed to execute the project.
- Required personnel skills and experience will be available
- Resources will be obtained within budget constraints
- Team members will be fully allocated to the project
- Resources will perform adequately
- Equipment reliability and uptime
Schedule Assumptions
These assumptions relate to the timing, sequence, and completion of project activities.
- Task durations will align with estimates
- Delivery dates from vendors will be met
- Stakeholders will provide approvals on time
- Testing and reviews will not cause delays
- Dependent activities can be sequenced as planned
Cost Assumptions
These assumptions deal with project budgeting and expenditure expectations.
- Costs of goods and services will not exceed estimates
- Market factors like inflation will not impact costs
- No unforeseen expenses will be incurred
- Contingency reserves will be adequate
Quality Assumptions
These assumptions pertain to the specifications, requirements, and performance outcomes of project deliverables.
- Requirements will be fully documented
- Designs/prototypes will meet needs and expectations
- Testing criteria will ensure quality standards
- End users will find solutions usable and effective
Organizational Assumptions
These assumptions relate to the support and involvement of the parent organization.
- Access to personnel will be granted
- Cooperation between departments will be sufficient
- Leadership support will continue
- Policy changes will not conflict
Technology Assumptions
These assumptions deal with technical systems, infrastructure, and tools needed for the project.
- Existing systems have capacity to support solutions
- New software can be integrated as expected
- Required bandwidth/internet will be available
- End user devices are compatible
- Vendors will provide technical support
External Assumptions
These assumptions relate to outside factors like weather, regulations, geopolitics or markets.
- No force majeure events will occur
- Government approvals/permits will be secured
- No new regulations will be imposed
- No major technology shifts or innovations
- No significant economic changes or events
Why Manage Project Assumptions?
While assumptions are necessary in project planning, relying on invalid assumptions is extremely risky. Proactively managing assumptions is critical for several reasons:
-
Minimizes surprises – Identifying assumptions allows contingency plans to be created.
-
Improves estimates – Questioning assumptions helps improve accuracy.
-
Refines objectives – Analyzing assumptions leads to development of realistic goals.
-
Allocates resources – Recognizing uncertain assumptions allows better budgeting.
-
Focuses team – Reviewing assumptions keeps stakeholders aligned.
Ignoring assumptions can lead to wasted resources, missed deadlines, cost overruns and products that miss the mark. Let’s look at strategies for assumption management.
How to Manage Project Assumptions
Here are effective ways to manage project assumptions:
-
Document all assumptions – Compile a master list and update regularly.
-
Perform assumption analysis – Assess validity and risks of each assumption.
-
Track with logs – Monitor assumption status throughout the project.
-
Assign ownership – Individuals should oversee specific assumptions.
-
Apply mitigations – Develop contingency plans if assumptions become invalid.
-
Update stakeholders – Keep everyone informed on assumption changes.
-
Incorporate into plans – Integrate assumption management into project plans.
-
Review frequently – Reassess assumptions as more information is known.
Managing assumptions is an iterative, ongoing process. Assumptions made early on may require revision later as more details emerge.
Key Takeaways
- Project assumptions address uncertain elements needed for planning.
- Examples include resource, schedule, cost, quality and technical assumptions.
- Assumptions carry risk if proven incorrect.
- Proactively identifying and tracking assumptions minimizes surprises.
- Documenting, validating and monitoring assumptions improves project success.
Incorporating assumption management into your project plans can help reduce risks and improve overall outcomes. Being purposeful about questioning and validating assumptions keeps projects grounded in reality.
What are Project Assumptions?
How do I create a project assumptions list?
1. Identify and Document Identifying your project assumptions is not something to do all by yourself while sitting at your desk alone. You need to include the team. They’ll be able to provide insight and help create a more comprehensive project assumptions list.
What are Project assumptions?
Project assumptions are project elements that project management teams usually consider true without specific evidence. If you’re working on a team, you might make these assumptions based on the current information and predictions you have about the life cycle of your project.
How do you manage assumptions in a project?
In order to identify, track and manage assumptions, you have to create a project assumptions log. This is a key piece of data for creating your project plan and reviewing it throughout the course of the project. It’s during the initiation phase of a project that a project manager will make the assumption log.
How do I identify assumptions that impact a project’s success?
Their unique perspective and expertise can contribute to identifying assumptions that might impact the project’s success. Create an Assumptions Log: Use an assumption log template to organize and compile your assumptions, or add them to a RAID template to track them alongside risks, issues, and dependencies.
