Why maintenance consumes most software cost in Software Engineering - See It in Action

Why Maintenance Consumes Most Software Cost

📖 Scenario: You are part of a software team that wants to understand why maintaining software takes more money and effort than building it initially.

🎯 Goal: Build a simple explanation using key points about software maintenance costs.

📋 What You'll Learn

Create a list called maintenance_factors with 3 main reasons why maintenance costs are high

Create a variable called initial_cost with the value 100000 representing initial development cost

Create a variable called maintenance_cost with the value 250000 representing maintenance cost

Create a summary string called cost_summary that explains maintenance cost is higher than initial cost

💡 Why This Matters

🌍 Real World

Software teams need to understand maintenance costs to manage budgets and timelines effectively.

💼 Career

Project managers, developers, and business analysts benefit from knowing why maintenance is costly to plan and communicate with stakeholders.

1

Create the list of maintenance cost factors

Create a list called maintenance_factors with these exact strings: 'Bug fixes', 'Updating for new requirements', and 'Adapting to new environments'.

Software Engineering

# Create the list maintenance_factors with the 3 reasons
# Your code here

Need a hint?

Use square brackets to create a list and separate items with commas.

2

Set initial and maintenance cost variables

Create a variable called initial_cost and set it to 100000. Then create a variable called maintenance_cost and set it to 250000.

Software Engineering

maintenance_factors = ['Bug fixes', 'Updating for new requirements', 'Adapting to new environments']
# Create initial_cost and maintenance_cost variables
# Your code here

Need a hint?

Use simple assignment with = to set the variables.

3

Write the summary explaining maintenance cost

Create a string variable called cost_summary that says:
'Maintenance costs more than initial development because it includes fixing bugs, updating features, and adapting to changes.'

Software Engineering

maintenance_factors = ['Bug fixes', 'Updating for new requirements', 'Adapting to new environments']
initial_cost = 100000
maintenance_cost = 250000
# Create cost_summary string explaining why maintenance costs more
# Your code here

Need a hint?

Use quotes to create a string and assign it to cost_summary.

4

Add a final note about ongoing effort

Add a comment line at the end of the code that says: # Maintenance is an ongoing effort that lasts longer than initial development

Software Engineering

maintenance_factors = ['Bug fixes', 'Updating for new requirements', 'Adapting to new environments']
initial_cost = 100000
maintenance_cost = 250000
cost_summary = 'Maintenance costs more than initial development because it includes fixing bugs, updating features, and adapting to changes.'
# Add a comment about ongoing maintenance effort
# Your code here
