Web Based Agile Software Development

1
Web Based Agile Software Development

• Mikio Aoyama, Niigata Institute of Technology
• Area Agile Software Development
• Presented by Tong Santee

2
Problem

• geographically distributed software development
  environment increase development cycle.
• How geographically distributed development
  environment meet the business market today that
  demands even more quickly deliver software
  product and also quick accommodate the
  requirement during development .

3
Answer for problem

• Agile software process ( ASP ) develop
• software quickly while maintaining the
• flexibility needed to respond to
• changing requirements in
• geographically distributed nature.

4
Brief history

• Since 1993, the ASP (agile software process )
  has been used in a large-scale communications
  software project at Fujitsu.
• The author form Japan and did large research in
  the concurrent development process model .

5
Agile software process( software process is
segmented so that team can work on different
release concurrently)
6
What is enhancement

• Enhancement
• - requirements are divided or integrated
  into a unit . a unit that comprise multiple
  functions or modules.
• enchantment have fixed time to development.
• - Multiple enhancements can be developed
  concurrently and integrate as a system , and then
  delivered to custom as a release.
• - An enhancement must be completed within a
  single release.
• major enhancement part of software tightly
  coupled
• minor enhancement part can divide between
  teams.

7
ASP Alter traditional management principle

• 1) The process architecture shifts from
  massive to modular.
• from the architecture view point , ASP
  consists two parts.
• upper stream process
• Lower stream process
• several concurrent software process assigned to
  upper stream and lower stream across multiple
  teams.
• each team iterates the 2 part, upper and lower
  stream release cycle.

8
ASP Alter traditional management principle

• The ASP changes the underlying process model from
  a staged model to concurrent asynchronous.

9
ASP is iterative with fixed cycle time. So large
volume development can be divided into multiple
release then they can be development
incrementally and concurrently .

• 1 group of functions incrementally developed in
  a series of release.
• 2 design and implementation is iterated until
  the sub-system come to an acceptable level of
  functionality.

10
Current development process two concurrent
multiple enhancements, multiple releases

11
Managing in Real Time (to manage concurrent
development successfully )

• Fixed cycle time is the Key to the ASP.
• Mandate projects processes have fixed cycle time
  development
• Set of concurrent process is regularly enacted
  over multiple release with a fixed time cycle.
• Mandate right information to right people at a
  short time cycle.

12
ASP management hierarchy ,distributed flat across
the organization , and vertically down through
the project, team, and personal levels.
13
The methods ASP use

• time based process en-action model
• Just in time process management
• These methods are play central role in managing
  ASP, and embedded into
• 1) Prime (Process Information Manager )
• 2) Web-based information sharing environment
• 3) WAIN (Wide-Area information Network )

14
ASP environment each layer of the framework
related directly to one of three major issues(
collaboration, information sharing, and
distributed computing)
15
ASP environment vertically integrated a wide
variety of components at three level, support
process and product management.
16
for operation layer ( use Client-Server
platform)

• client Individual developer and team leader
  access it .
• Team server Team leader and project leader
  access it.
• Project server Project leader and upper-level
  management access it.
• every clients and servers database is build
  use the schema structure. Use SQL operation and
  Unix machines for server, Microsoft Window for
  client.

17
the information layer ( use Wide Area Information
Network )

• WAIN is designed to manage the structured,
  semi-structured , and unstructured design
  documents.
• use web and e-mail system.
• Encapsulate the structure of various design
  documents and provide uniform access methods to
  the documents.
• Enable developers to navigate across the
  distributed environment.

18
the collaboration layer ( use Prime --Process
Information Manager)

• Support planning and execution of whole software
  process
• in time guidance of individual developers
  software process.
• Prime collects test results through the extranet
  from the distributed team server. Then generates
  the daily progress and bug charts at the team and
  project level.

19
An example use PRIME
20
Experience and Lesson Learned

• use distributed continuous integration to avoid
  integration headaches
• Have each site send ambassadors to the other
  sites
• Use test scripts to help understand the
  requirements
• Use short iterations
• Separate team by function not activity

21
Comparison of the Water-fall Process and the ASP
22
Scope of research

• Major reason why organization have problem with
  adopting agile methods -------- dont
  underestimate culture change.
• The benefit of the agile from the client.
• The future of offshore and agile.
