Background
Project Overview Achievements Architecture
Risks Reflections Project Metrics Summer
Semester Plan Quality Assurance

• Service Migration and Reuse Technique (SMART)
• Technique to analyze the effort, risk and cost of
  migration of legacy components to a target
  Service-Oriented Architecture (SOA) environment
• Three Elements
• Interview Process
• Analysis Process
• Evolution Process

5
The Problem
Project Overview Achievements Architecture
Risks Reflections Project Metrics Summer
Semester Plan Quality Assurance

• Entire SMART process is manual
• Interview process
• Dynamic interview environment makes it difficult
  to record data in an organized way
• Manual consolidation post-interview
• Risk analysis reports
• Overload of data
• History tracking and trend application difficult

6
The Project
Project Overview Achievements Architecture
Risks Reflections Project Metrics Summer
Semester Plan Quality Assurance

• Goal To improve the efficiency of the SMART
  process
• Streamline SMART engagements
• Efficient data collection
• Automated interview guide (SMIG) navigation
• Automated data consolidation and report
  generation
• Develop a centralized server and
  interviewer-operated client software

• Business Goals
• Reduce length of SMART engagement
• Reduce cost of SMART engagement
• Support transition of SMART
• Main Quality Attributes
• Usability of Interview tool
• Security (IP concerns)
• Modifiability

Constraints
Project Overview Achievements Architecture
Risks Reflections Project Metrics
Summer Semester Plan Quality Assurance

• Business constraints
• SMART Engagements involve SEI personnel
  travelling to client locations and performing
  interviews. Data taken in these engagements must
  be consolidated into a central repository.
• The SMART team has no budget for commercial
  software any third-party software must be free.
• Technical constraints
• Java will be the language used.
• The ZEN Tool will need to work on a Windows XP
  machine.
• Connection to SEI requires using virtual private
  network (VPN). This is as per SEI rules.

Reflections and Lessons Learned
Project Overview Achievements Architecture
Risks Reflections Project Metrics
Summer Semester Plan Quality Assurance

• Communication breakdown
• Included mentors in email threads
• Instituted common working hours
• Distributed development
• Use emails, skype, wiki, phones
• Dont depend on emails for timeliness
• Wiki worked very well for our team
• (for transclusion and as a repository)
• Use experts
• Architectural improvement (Felix and Tony)
• Security concerns (Paulo)
• Licensing (Ed)
• Depth vs Breadth in Experiments
• Refocus on the architecture
• Pros and Cons of a technical client
• Donut points is a good motivator!!!

Estimation for Summer
Project Overview Achievements Architecture
Risks Reflections Project Metrics
Summer Semester Plan Quality Assurance

• Initial Estimation Approach
• Component-based Estimation
• Two-person Wide-band Delphi
• In cases of large differences, addition of third
  estimator
• Correction of estimates based on experiment data
• Ongoing Estimation Approach
• Productivity and size tracking
• Correction of spring estimates

Team Goals

• The ZEN tool shall provide the functionality
  specified by the must-needed requirements in the
  SRS document within the given time frame.
• The ZEN tool will provide for all the quality
  attributes which the client ranks must-have
  within the given time frame.
• We will share the workload evenly and follow the
  ZDM process throughout the project.
• We will reflect on all our activities as
  documented in the proposals in each iteration at
  the first meeting of every new iteration and
  compare it with our processes, to identify
  actions which need to be taken for the next
  iteration.
