Just as an
organization uses a
business plan to provide a framework for the conduct of
business, systems have architectures with goals, objectives,
policies and strategies. A system architecture provides a
framework for components which connect and work together
seamlessly, yet it is dynamic enough to allow for change and
expansion for future growth. System components include the
basic constituents (hardware, software, facilities,
personnel, data, materials, services, and techniques) that
make up a system and satisfy one or more requirements in the
functional architecture.
Customer requirements form the starting point for
business architectures and information architectures. A
business architecture describes the functions, processes,
applications and activities that you perform in running your
business. An information architecture defines categories of
information needs - for information users and for diverse
locations.
As an architecture evolves, it is evaluated to ensure
that requirements continue to be met. The details of the
architecture grow as the final architecture is designed.
Even after the system is implemented, the architecture must
adapt to incorporate technology changes and product
improvements. Evaluations take the form of reviews - focused
on requirements and risk management-tests, and analyses such
as modeling, simulations and prototyping of work flow,
usability, reliability, sizing, and performance. CSC
can design an architecture responsive to your current
business needs yet adaptable to your future requirements.

What We Offer ||
Success Stories
Requirements Analysis and System Design
Customer requirements form the basis of any system
architecture. CSC collects, analyzes and verifies
that these requirements are adequate, complete and
achievable, and that they meet the mission of the
organization. We then model, simulate, and prototype the
requirements to make sure we can design a best-value system
for our customers. Next, we transform customer requirements
into system product and process designs, generating
information for our customers' decision makers.
Specifications, Reuse, Trade-Offs, and Alternatives
Specifications are a critical part of system design.
System and component specifications describe inputs,
outputs, and processing algorithms. They also identify reuse
options, based on commercial-off-the-shelf (COTS)
evaluations, and reuse library inquiries. Trade-offs are
made continually through the design process, facilitating
selection among available alternatives. Our evaluations can
reduce program risk, cost and time.
Security Mechanisms and Procedures
CSC security experts are skilled in data and
access security, areas that are most important to systems
that require data privacy. Record or field locking
mechanisms are evaluated with requirements that specify
which records or fields must be locked at the same time.
User groups are assigned access privileges based on the
roles they may play when using system functionality.
Mechanisms and procedures to allow administrators to change
access privileges are developed; all security mechanisms and
procedures are verified and validated through reviews and
audits.
System Integration and Testing
Integration is the process of combining and testing
system components to form a unified product. CSC will
confirm that hardware and software are properly configured
and functioning correctly, and that installation needs are
identified. Our integration testing validates that
requirements are met and verifies that the design is built
right; regression testing ensures that design changes do not
have adverse impacts on previous test results.
Risk, Schedule, and Cost Management
As requirements are defined, we identify risks which may
impact budget, schedule, performance, and quality. The
probability of occurrence is identified for each risk, and
risks are monitored accordingly. Detailed prevention and
mitigation plans are developed for medium and high risks.
Audits and
technical/management reviews ensure system
effectiveness; balance cost, schedule, performance, and
risk, and control system configuration.
Several systems developed by CSC (e.g., AUTODIN,
AUTOVON) have been in continuous use for more than 30 years.
These operational systems have been periodically enhanced
without disruption of service. We have inserted new
technology and deployed additional components using cost -
effective, low-risk procedures to minimize the impact on our
customers' mission. We also performed safety and quality
control audits and analyses, and performed corrective
maintenance on the end-to-end systems with 99.9%
availability. |
