So, what grade is appropriate for "no errors" work?

Grading (3)• What's a professor to do?
• Conflicting messages from MSOE
• Which is closer to employee evaluation?
• Is this the choice?
• Make students happier now
• Make graduates happier later
• Duty: preparation for lifelong career

How to Get an "A"• Be "outstanding"
and "exceptional"?
• What does that mean?
• Go a little beyond the requirements
• Demonstrate learning and thinking
• Talk to the prof

Process?
• How should we plan and execute a project of moderate size (small team)?
• How would you do it?
• What was the process you used in SE 1011/SE 1021/CS 2852?
• What was good or bad about it?

Practice vs Process• Practice = “what we do”
• Analyze requirements, create architectural/detailed designs, implement, verify
• Process = “how & when we do it”
• Plan, organize, measure, make/meet commitments, ensure quality, control, improve, adapt
Copyright © 2012-2014 by Mark J. Sebern
Activities• Planning & tracking
• Requirements analysis & specification
• Architecture & high-level design (HLD)
• HLD review
• Detailed design
There are many different ways to break down software development activities; this is just one
way of doing it.
• Detailed design review
• Implementation (coding)
• Code review/inspection
• Unit testing
• Integration testing
• System testing

Traditional Model• Requirements: talking to
customer• Design: How to impl. Reqs• Implementation: coding• Verfication: testing• Maintenance
• Covers all necessary products
• Similar process to other engineering disciplines

Known as waterfall model:• Water gently flowing down
hill towards a goal…• But what happens if
discover a problem?• Is this really more like
Niagara Falls?

Process Models• Process models provide
frameworks for organizing software development activities
• One pass, sequential (“waterfall”)
• Iterative/incremental
• “Agile”: XP, Scrum
• SEI: PSP/TSP
In SE-2800, we will use a
process model based on Scrum

Process GoalsOverwhelmingly, software development managers and stakeholders ask us for
two things:
Copyright © 2012-2014 by Mark J. Sebern
Comparing Iterative Models
Waterfall model/ Predictive Process Scrum
Planning model
Heavy focus on process data,
tracking
Team experience, integrated customer
Quality manageme
nt
Tests written byexternal agent
Short cycles to provide
monitoringFinal
product definition
Schedule target, defined
Flexible, adaptive

Course Goal
• Experience with one approach to software process
• Why Scrum?
• Gaining acceptance in industry
• Easier introduction: fewer process artifacts, learn as you go
Copyright © 2012-2014 by Mark J. Sebern
Textbook• Essential Scrum
• A Practical Guide to the Most Popular Agile Process, Kenneth S. Rubin
• Good reference on process framework – not a real textbook
• Needs supplement on practices
Copyright © 2012-2014 by Mark J. Sebern
Tools• Atlassian
• JIRA/Agile (plan/track)
• Confluence (wiki)
• Bitbucket
• Git repository
• JUnit
• Test automation
• Jenkins
• Continuous build
