TITLE IBM REDISCOVERY/2
ABSTRACT ReDiscovery/2 helps the user identify usable and reusable
parts and retrieve them for analysis or future use.
ReDiscovery/2 allows a user to create catalogs from
workstation or local area network (LAN) files and selected libraries,
add additional information about the part, search for the part based
on its content or descriptive information, and retrieve the part from
the library. ReDiscovery/2 uses ReDiscovery/MVS to provide an
interface to parts in MVS data sets and selected MVS libraries. To
use ReDiscovery/2 on the MVS platform, see IBM Software Announcement
293-606, dated October 12, 1993.
Studies indicate that being able to find and reuse design and
code has a major positive impact on development productivity,
quality, and time required to deliver new applications. The benefits
vary with the maturity of the organization's reuse program, and can
be expected to increase as the organization's reusable parts
increase.
The first customer shipment of ReDiscovery/2 and
ReDiscovery/MVS will be by November 22, 1993 to an already selected
set of customers. These customers will participate in a program that
is designed to validate that IBM has achieved the quality objectives
for ReDiscovery/2 and ReDiscovery/MVS in a variety of production
environments. When these customers confirm that IBM has achieved its
quality objectives, IBM will announce general availability and
ordering information in a general availability announcement letter.
Planned Availability Date: To be announced at a later date.

IN BRIEF . . .
IBM ReDiscovery/2 and IBM ReDiscovery/MVS Promote Reuse!
IBM ReDiscovery/2 and IBM ReDiscovery/MVS allow the
application developer to:
o Quickly locate reusable components based on flexible search
criteria.
o Automatically catalog component descriptions from existing
libraries.
o Organize component descriptions using a tailorable classification
scheme.
o Manage, enforce standards upon, and tailor reuse catalog
information.
o Retrieve components and launch an editor of choice or other tool
to complete the application build process.
o Access parts on both the workstation and in a local area network
(LAN) environment (OS/2 (R) files and popular library management
systems).
o Access parts in MVS/XA (TM) and MVS/ESA (TM) environments (PDS
data sets and popular library management systems).
o Register interest in a part to be notified when the part is
changed.
ReDiscovery/2 has an easy to use, CUA (TM) conforming,
object-oriented, graphical user interface.

OVERVIEW DESCRIPTION
The features available in ReDiscovery/2 can save application
programmers significant time by automating what would otherwise be a
manual process. Reuse becomes attractive to programmers when search
and selection of items such as code components, test cases, design
models, and documentation are fast, easy, and complete. Reusing code
is a faster way to create new applications than writing new code.
This savings can help improve programmer productivity, application
quality, and reduce the time it takes for a programmer to complete
the task, which can help to reduce the total backlog for the
customer.
Customers should achieve value by reusing code which can
increase productivity and quality, and reduce elapsed time to
delivery of programs. When customers choose to reuse larger
elements, such as business models or even functional models, even
greater percentages of improvement may be possible.
SYSTEMS MANAGEMENT -- APPLICATION DEVELOPER PRODUCTIVITY
ReDiscovery/2 helps application developers be more productive by
supporting a reuse environment. ReDiscovery/2 allows users to
automatically build descriptions of reusable parts from multiple
disparate sources, add additional classification information, then
search these catalogs to locate needed parts for maintenance of
current applications or development of new applications. Organizing
parts by classifying them into structures or by grouping them into
components, and then providing summary information about the
structure or component, allows a user to:
o Search applications for needed parts
o Determine what the component functions are
o Research where and when the parts have been used or referenced
ReDiscovery/2 provides the application developer with a tool
that will reduce, if not eliminate, manual searches for code that can
be used in new application generation. The easy availability of
reusable code encourages application generation from available parts,
rather than writing all new code. Coding time, testing time and
future maintenance time can be significantly reduced by using
existing, tested code. A tool which automates the search process for
reusable parts makes a corporate reuse strategy feasible.
GROWTH ENABLEMENT -- CONSTRAINT RELIEF
ReDiscovery/2 provides a means to create new applications faster than
writing new code, thereby potentially reducing application backlogs.
Both programmer constraints and company constraints caused by lack of
needed new applications can be eased.
PRODUCT POSITIONING
ReDiscovery/2 and ReDiscovery/MVS are positioned to provide
key reuse capabilities to our customers. Reuse can be applied at
several entry points across the application development life cycle:
o Business modeling requirements definition and design
o Application development
- Requirements specification
- Design
- Code
- Test
- Maintenance
ADDITIONAL PRODUCT INFORMATION
The following illustrates some of the ways that customers can derive
value by using ReDiscovery/2 and ReDiscovery/MVS. Potential values
can include productivity gains, quality improvements, and reduction
of elapsed development time.
o Reuse -- where an application development professional
(programmer, system analyst, AD manager) identifies usable or
reusable parts.
The following are necessary to allow customers to reuse
parts:
- A part is useful -- it does something its user needs
- The user knows it exists (can find it)
- The user can acquire it
- The user knows how to use it
- The user can combine it with other parts -- usually without
having to modify it internally
- Somebody will supply maintenance (unless the part is
inexpensive)
- There is a measurable net benefit to the user to use it.
ReDiscovery/2 and ReDiscovery/MVS can help a user perform
reuse by answering basic premises in the above list, questions
such as "Is there a place to look for something?", "Does it
exist?", and "How do I get it"?. ReDiscovery/2 provides a set of
metrics and reports to help quantify the value of the part. To
effectively implement reuse, the customer must support an
organized approach to supply parts and to reuse parts.
- Supply -- Cataloging reusable parts
ReDiscovery/2 and ReDiscovery/MVS automatically
capture information from existing parts sources and begin the
organization process. The user may use the default
classification scheme (standards) or tailor a new one to
complete the organization and description of the parts.
- Reuse -- searching for and selecting parts
The reusable parts catalog can be browsed in a variety
of ways, including keyword search, structured search, and
wild card search. These methods, working on the
classification scheme and the raw data, will identify
reusable parts for the ReDiscovery/2 user.
Once function and matching code have been located, an
analysis can be performed to determine which is more cost
effective:
-- Using the located part as is
-- Modifying a copy of the located part to enhance function
(that is, redevelop)
-- Code a new part using the identified function as a base.
The Reuse Support Strategy is part of the overall goal
to improve application developer productivity. Reuse can
affect a wide spectrum of application development activities
and a wide variety of reusable components.
MAINTENANCE
By comparing (benchmarking) how long researching the affected modules
takes manually versus with using ReDiscovery/2, costs for reducing
the understanding or migration time can be calculated. This cost
reduction may be substantial.
SUMMARY
Users will discover that ReDiscovery/2 and ReDiscovery/MVS can help
them catalog their host files and libraries, organize their private
workstations, and manage their servers.
ReDiscovery/2 provides access to workstation or LAN files and
selected libraries. ReDiscovery/2, in conjunction with
ReDiscovery/MVS, provides access to popular MVS library systems.
