Personal Design and Development Software ProcessPD2SP

“The unexamined life is not worth living.”


cynics guide to personnel management
Cynics’ Guide to Personnel Management
  • Those who work get to keep their jobs.
  • Raises become effective when you do.
  • It’s better for you to tell them than for them to find out.
what it means to be effective
What It Means to be Effective
  • As software professionals you must know your own performance.
  • You should measure, track, and analyze your work.
  • You should learn from your performance variations.
  • You should incorporate these lessons in your personal practices.
  • Measure and analyze your personal design and development software process (PD2SP).
  • Use process data to improve your personal performance.
  • Understand variation in your work patterns.
  • Plan and estimate software development tasks.
what metrics do you need
What Metrics Do You Need?
  • Time:
    • Class, Prep for class, Recording time, Design time, Planning Time, Programming, Debugging.
    • Provide both planned and actual times.
  • Code: Quality and Quantity.
  • Results: Demonstrated Correct, Complete Code.
cost of pd 2 dp
Cost of PD2DP
  • The time required to learn and use it.
  • The emotional cost of maintaining the needed discipline.
  • The potential risk to your ego.
benefits of pd 2 dp
Benefits of PD2DP
  • The insight you gain into your talents and abilities.
  • The stimulation of an almost unlimited stream of ideas.
  • The framework provides for personal improvement.
  • The degree of control you gain over your time and work.
  • The feeling of pride and accomplishment.
  • An improved basis for effective teamwork.
  • The conviction to do the job the way you know you should.
by the end of the semester
By the end of the semester:
  • You will understand some methods are effective for you.
  • You will do better work.
  • You will have long-term improvement goals.
pd 2 sp principles
PD2SP Principles
  • The quality of a software system is governed by the quality of its worst components.
  • The quality of a software component is governed by the individual who developed it.
  • You are governed by your
    • knowledge
    • discipline
    • commitment
what do you know about your software development skills
What do you know about your software development skills?
  • Can you
    • Design, estimate, and plan your work?
    • Meet your commitments?
    • Resist unreasonable commitment pressures?
  • Do you
    • Understand your ability?
    • Have an improvement plan?
a pd 2 sp also provides
A PD2SP Also Provides
  • A basis for developing and practicing industrial-strength personal disciplines.
  • A discipline that shows you how to improve your personal process.
  • The data to continually improve the productivity, quality, and predictability of your work.
what is a pd 2 sp
What is a PD2SP?
  • A personal process for developing software
  • defined steps
  • forms
  • standards
  • A measurement and analyses framework to help you characterize your process
  • A defined procedure to help you to improve your performance
sei capability maturity matrix
SEI Capability Maturity Matrix
  • Broadly agreed-upon definition of how a software organization matures and improves.
  • Based on manufacturing process improvement and “best practices” from software engineering
  • Some dramatic successes.
each key process area has five common features
Each key process area has five common features:
  • Goals to be achieved;
  • Ability to perform;
  • Activities performed;
  • Measurement and analysis;
  • Verification
pd 2 sp overview1
PD2SP Overview
  • Since this is so late in your education, can’t do it all in one course.
  • Focus on how to make your more efficient in time
  • We’ll just do the first step.
pd 2 sp0

Identify your current software development process including:

  • Planning - Produce a plan to do the work.
  • Development - The actual software development.
  • Postmortem - Comparison of actual performance with your plan.
the measurements will be
The measurements will be
  • Based on your current process.
  • Measure where you spend the bulk of your time. We will use minutes as the base granularity for data to be meaningful.
  • Defect Recording. A defect recording log is used to hold data on each defect found and corrected.
don t panic

Don’t Panic

You will NOT be graded on how long it takes or how many defects you find

thepd 2 sp0 summary
ThePD2SP0 Summary
  • Your original estimate of the LOC you expect to develop.
  • The actual LOC you developed.
  • Your original estimate of the time required for each phase.
  • The actual time required for each phase.
  • The total number and the percent of defects injected in each phase.
  • The total number and the percent of defects removed in each phase
task planning
Task Planning
  • Task planning involves estimating the development time and completion data for each project task.
  • It also provides a basis for tracking schedule progress.
  • Time and Schedule Management
  • Requirements Management
  • Design and Work Breakdown Structure
  • Development
  • Reporting
  • Earned Value Estimation
time and schedule management
Time and Schedule Management
  • Enter initial project data in the project plan summary (PDSP0).
  • Complete Initial Time Schedule Template (SPT).
  • Begin Time Recording (TRT).
requirements planning
Requirements Planning
  • Complete the Requirements Work Template (RWT) in the Excel workbook.
    • Constraints are logical statements
    • Criteria are performance statements
design and work breakdown
Design and Work Breakdown
  • Use developed requirements document.
  • Complete a Work Breakdown Structure
  • Estimate the required development time.
  • Complete the task plan (WBS).
  • Complete the project plan summary with actual time, defect, and size data.
  • Complete the PIP (PD2SP0).
  • Coding Standard
  • Size measurement
  • Process improvement Proposal
rules of the game
Rules of the Game
  • Please keep accurate track of time.
  • YOU WILL NOT BE GRADED ON YOUR TIME OR QUALITY from this report!! Quality measurement comes from testing
  • Keep your programs simple. You will learn as much from small programs as from large ones.
  • Keep your reports and standards simple and short.
  • Do not hesitate to copy or build on the PD2SP materials.
rules of the game ii
Rules of the Game II
  • Do it right the first time. If you are not sure, find out.
  • Software is not a solo business so you do not have to work alone.
  • You must, however, produce your own estimates, designs, and code.
  • You may have others review your work and you may change it as a result. You should note this help in your process report, include the review time you and your associates spend, and log the defects found.
  • Your process report must be:
    • complete
    • legible
    • in the specified order
  • Your process data must be:
    • accurate
    • precise
    • self-consistent
the pd 2 sp0 process
The PD2SP0 Process
  • A simple defined personal process
  • Use your current design and development methods.
  • Gather data on your work:
  • time spent by phase
  • defects found in compile and test
prepare a summary report
Prepare a summary report.
  • A project plan summary form
  • A process script
  • A time recording log
  • A defect reporting log
  • A defect type standard
more process
More Process
  • Planning - estimate development time
  • Development - develop the product using your current methods
  • Postmortem - complete the project plan summary, with the time spent and defects found and injected in each phase.
  • Design - design the program, using your current design methods
defect type standard
Defect type standard
  • Date defect was found.
  • Defect number.
  • Defect type (documentation, syntax, assignment, interface, etc.).
  • Phase where defect was injected.
  • Phase where defect was removed.
  • Time it took to fix the defect.
  • If injected while fixing another defect, that defect’s number.
  • A succinct description of the defect. The project plan summary holds the estimated and actual project data.
