| The Saggezza Application Lifecycle Management
offerings help clients with management, support, extension and transformation
of their applications. Saggezza combines extensive experience in architecting
& designing complex solutions with expertise in maintaining and re-engineering
systems, thus enabling it to draw a solid roadmap for applications. This
proposition is based on the Saggezza Global Resource Model, which optimizes
teams from a skills and cost perspective.
Application Assessment
The objective of this phase is to identify the critical gaps and develop
a roadmap for application evolution. The gaps could be in the development
process, the documentation or interfaces. Thus, several of the following
analyses may be conducted:
- Code analysis (supported by tools)
- Run-time system analysis
- Interface analysis
- Business processes & rules analysis
- Financial analysis (cost of ownership)
Application Management Process Establishment
This phase is aimed at establishing the process for plugging
the gaps identified. At the end of this phase a detailed Release Plan
with well-defined milestones and feature-function lists are laid out for
the next phases.
The following activities are involved:
- Establish Development Process for new functions
- Define Service Level Agreements for support and maintenance
- Chalk out the medium term release cycle
Saggezza will also set up an offshore development environment and constitute
its team for addressing the identified gaps.
Application Upgrade
When necessary, Saggezza undertakes upgrades of the application to fix
key issues and to ensure that the application runs on top of supported
platforms (HW, OS, System SW, Tools). This phase also covers maintenance
activities identified earlier. The services will be administered under
the defined Service Level Agreement.
Transform
Application Extension
The objective of this stage is to extend the reach, flexibility and integration
capabilities of the application. Legacy Extension methodologies can range
from simple (screen scraping) to complex (OO decomposition and wrapping),
based on the needs of the business, cost and time-to-market considerations
as well as projected life of the extended application. Legacy extension
tools and techniques are used to provide system inventory, program flow
understanding, code understanding and code modification capabilities for
a wide variety of languages, databases and transaction environments. The
techniques used could be screen scraping, database gateways, XML integration,
or database replication.
Application Transformation / Replacement
Based on the application experience built up in the previous phases, Saggezza
will be in an excellent position to assist with the transformation of
the application “under architecture”.
Saggezza assists in mapping process flows, user experience and business
rules for the current application and performing a gap analysis vis-à-vis
the desired state. Next, we ensure that the required functionality is
positioned in the context of enterprise or domain architecture. The options
for Buy/ Build/ Re-Engineer are reviewed and the New Application’s
ROI is determined.
Saggezza then develops and integrates the new application under the guidelines
of the architecture, taking into account the requirements for reliability,
availability, manageability, performance and security. In the case of
a rebuild strategy, Saggezza utilizes tools that provide business rules
identification, code slicing, code modification or transformation from
one language to another.
