Software is very special. I is grand, spectacular, regenerative and perpetual source of value---like nothing else we know. Perhaps for this very reason it is misused and wasted. By cooperatively REUSING ALL ARTIFACTS of software, we can reap unheard of benefits repeatedly. Here is an outline of how we can do it. That is ReSAR. Let's start.

1. ReSAR: Reusable

2. Reuse and Engineering
In engineering, systems are
designed by composing
existing components that
have been used in other
systems.
---Ian Sommerville
 So, Engineering is
REUSING
 In addition to it being
 Systematic application
of methods and Tools ..

4. Computer Software—Very Special
 Every cost-less copy
 Delivers VALUE
 EVERY time it is executed
 It is active and generative
 No material defects
 No manufacturing defects

5. REUSE of Software
Much talked of but NOT used enough

6. (Low Cost + High Value) X # Copies
 With a catch
 The first working
software costs a lot
 But it can be
contained by reusing
some available parts
of other systems
 See the advantage of
 REUSE of Software
 This is closest to
inexhaustible source of
value or worth

7. Software Artifact
What a software
artisan creates or
produces
 Any software item or document /
diagram for development, testing or
operation of software
 Definitions, standards, methodology
templates, checklists, BRD, SRS of
system or sub-system, component,
Software Architecture, design
documents, source & object codes, test
spex, test data, reports …..

8. Artifacts are of immense value
 And if they can be
copied at NO cost and
reused,
 Their value multiplies
several folds
 But does it really work?
 No, not ordinarily
 Software engineering has
been more focused on
original development
 BUT IT NEED NOT BE

9. Grow
So here is a proposal
 To have REUSE policy
 Learn techniques of
REUSE….
 Set up ReSAR
 Manage
 Grow within & across

10. Set up & Operate ReSAR

11. Create ReSAR
 ReSAR is (to be) created &
 Incorporated as
 A Professional Organization
For Profit
 By founder members
who are:
 Software scholars,
 Professors or
 Professionals
 Business
professionals
 Any one helpful

12. Registered Members & Management
 Then members can
register as individuals
 Corporate members?
 For the Mission of
ReSAR…to be crafted
 Chief Editor,
 Editors,
 Referees and
 Business Manager
 Elected by the
members of ReSAR

13. Generating WORTH & Delivering Value
Let’s benefit & Share

14. Artifact Worth Assessment & Pricing
 Editors & Business Managers
 Assess the worth W of artifact
 Fix Sale Price SP
 SP = W/n,
 n = 10 to 1000 or more

Worth W of Artifact
Sale Price SP

15. Owning Artifact & Adding Worth
 True inventor member
is the owner of artifact
 Who non-exclusively
assigns rights to ReSAR
 ReSAR or members DO
NOT pay for using the
artifact
 Members improve the
worth of artifact
 By testing, using &
refining it
 Its initial quality is not
crucial but using it is

That is
the
benefit
of ReSAR

16. Ownership, Sale & Sharing
 Sale: To external entities
 Sales proceeds are shared
7:3 till Worth is realized
 Thereafter it is 3:7

17. Potential Artifact is nurtured
 Artifact has to be sound, usable & must work
 It is accepted into ReSAR based on
 Referee recommendations & evaluation reports
 Artifact is a PACKAGE with relevant attachments,
instructions, cautions, certification & disclaimers
 The whole community works to increase its worth
