The problem definition stage involves identifying and understanding the problem's context, objectives, and
constraints
What is an example of a constraint in problem-solving?
Budget limitations
Objectives in
problem definition
describe what you aim to achieve by solving the problem.
Defining the scope involves identifying the boundaries of a project, including objectives, deliverables, and
limitations
Steps in defining the scope of a project
1️⃣ State objectives
2️⃣ List deliverables
3️⃣ Identify limitations
What does SMART stand for when establishing objectives?
Specific, Measurable, Achievable, Relevant, Time-bound
Gathering relevant information involves collecting and analyzing data from sources such as surveys, databases, literature reviews, and
interviews
Statistical analysis is a technique used to uncover
insights
from collected data.
Match the key aspect of problem definition with its description:
Context ↔️ Background or situation surrounding the problem
Objectives ↔️ What you aim to achieve by solving the problem
Constraints ↔️ Limitations affecting the solution
SMART objectives are specific, measurable, achievable, relevant, and
time-bound
What are constraints in project feasibility and practicality?
Financial, time, technical limitations
Documenting problem definition ensures a shared understanding among
team members
.
Key stakeholders in problem definition are individuals or groups affected by or involved in the
problem
