Analyze the Problem

objectives
Define “problem analysis” and its goal.

Describe activities for problem analysis.

Identify the stakeholders.

Gain agreement on the problem.

Find actors and define system boundaries.

Start development of the project Vision.

Define a problem statement.

Identify constraints on the project.

Establish common vocabulary.

Objectives
problem analysis
Is the process of understanding real-world problems, how they relate to stakeholder needs, and proposing solutions to meet those needs.

What is the goal of problem analysis?

Gain a better understanding before development begins.

Identify root causes.

Help find the right solution.

Avoid the “Yes, but…”

Minimize extra work.

Problem Analysis

What is the real problem?

a problem can be defined as the difference between things as perceived and things as desired

problem analysis steps
Identify stakeholders.

Understand the root causes.

Gain agreement on the problem definition.

Identify constraints on the system or project.

Identify and validate the solution against the root causes.

Define the solution system boundary.

Problem Analysis Steps

Problem

Identify stakeholders for problem.

Root cause analysis.

Business problem defined

Actual problem identified

and defined

Understand the problem in the context of the business goals.

Problem validated/adjusted

Choose the best solution(s) to meet the goals.

Reassess that the solution idea is the best solution.

Elicit Requirements

Best solution identified

Expand stakeholder list for solution.

stakeholders definitions
Stakeholder

An individual who is materially affected by the outcome of the system or the project(s) producing the system.

Stakeholder Representative

A stakeholder representative represents one or more stakeholders. They are directly involved in the steering, shaping, and scoping of the project.

Stakeholders: Definitions
identify the stakeholders
Each group of stakeholders needs a representative.

Not all stakeholder groups need to be consulted.

Some will provide requirements.

Customers, users, system administrators

Some may not provide requirements.

Shareholders

Identify the Stakeholders

Who are some of the stakeholders for your projects?

Rank in order. Use the 80-20 Rule to focus on the top contributing causes to address the greatest portion of the problem.

understand the broader context of the problem
A lack of understanding the business and its goals increases risk.

Does the problem have an organization/process component?

Does the team understand the domain in which the problem exists?

Does solving the problem present the opportunity to make process improvements?

Understand the Broader Context of the Problem
