APPENDIX A: attn/ Reidar Conradi, IDI at NTNU, 12 Feb. 2008 some relevant OSS material in the sw.eng. group.

1.1 Why engage more in OSS activities?

Do solid empirical research on OTS technologies and their industrial application.
Try to jointly start some new R&D projects, in order to hire PhD students and postdocs to do such research:

New STREP-project in EU (proposal submitted in 2009):
OTS-Lib, a federated web portal with Web Intelligence and surrounding Communities-of-Practice to more effectively retrieve and integrate suitable OTS components when building own software.
New nat'l OSS project, user-driven BiA/BIP:
e.g. for public services, integrator focus (not proposed, open sttaus).
New nat'l OSS-project, researcher-driven VERDIKT project:
action research of OSS development (proposed as MAIN-SOFT in Nov. 2009).

2. Main research results in COTS/OSS/reuse so far

Generally on reuse: or rather called systematic reuse.

2.1 Reuse advantages, general
- lower cost,
- shorter lead-time or time-to-market,
- higher quality,
- higher standards compliance,
- more modern architecture, and
- possible inclusion in a supportive net-community of matching reusers.

2.2 Two main reuse tasks: development FOR reuse (making an investment in reusable assets) vs. development WITH reuse (reusing previously made assets):

FOR reuse: Hinders in making reusable assets: delayed and unknown payback, although usually after 1.5 reuse occurrences.
Similar "delays" in all QA and SPI work, though.
So "development-for-reuse" must be integrated into existing processes and company policies.
But hard to design reusable assets in first attempt in unfamiliar domains Johnson and Foote write that useful abstractions are usually designed from the bottom up; i.e. they are "discovered not invented", see [Johnson98] Ralph E. Johnson and B. Foote: "Designing Reusable Classes", Journal of Object-Oriented Programming, 1(3):26-49, 1998.
So often reengineering in retrospect to make high-quality reusable assets.
>WITH reuse: Hinders in "development-with-reuse": unclear and even unknown properties of relevant candidates, and "not-invented-here-syndrome". Also licensing/price issues.
Modern infrastructure, middleware and interfacing standards - such as Java-SOAP, components models like CORBA and .Net, Service Oriented Architectures (SOA) and Web Services - have reduced the need of extra "glueware". This has facilitated the recent flood of available assets of COTS/OSS or even internal origin.
Now ca. 30 special reuse repositories and portals, containing millions of publicly available software assets, mostly documented in partial, unsystematic or non-standard ways. So component selection is not easy from such sources.
Also "glueware" to interface with and "addware" to supplement component functionality, cf. Morisio04.

2.3 Meta-information

Need meta-info to classify and later retrieve and evaluate the stored software assets/components. Four axes of classification attributes:

Functional/domain - mostly static; by component provider?
Non-functional (= "quality") - mostly experience-based and thus dynamic, w/ sensitive info!, done jointly by provider/user?
Platform properties: hardware and software platform, API structure, technical organization.
Non-technical properties (price and licensing terms, trust, reputation, available support, market share, customer policy, delays of announced upgrades etc. etc.) - again mostly dynamic, sometimes sensitive, and done jointly by provider/user? The most important issues are often such non-technical ones. Must also consider impact of previous policy or business decisions, e.g. that my company has already chosen the xxx DBMS and the yyy groupware tool, or that my company either buys Microsoft software or OSS.

There is a generic problem with insufficient and unreliable documentation of especially the non-functional and non-technical aspects. But even for functional attributes, a formal API of a component does not normally document hidden or internal components dependencies: E.g. that a new ComponentA will require Version.2 of a DBMS named xxx, while existing ComponentB already uses Version.1 of this DBMS - and your technical support refuses to maintain more than one such version.

2.1 Possible user roles for handling OTS components:

End-user of OTS binaries as "freeware", e.g. Linux, Open Office, emacs, Apache, MySQL, Adobe Acrobat etc.
Integrator of OTS in own software, hereunder:
- Reporting defects back to provider + may also do minor code changes.
- Reporting desired changes/upgrades back to provider + similarly.
OSS co-developer or COTS subcontractor.
Main OTS developer or provider.

3. Empirical studies of COTS and OSS mainly by NTNU in 2002-2008

3.1 (paper by Basili and Boehm on COTS usage)

See IEEE Computer 1999.

3.2 Initial study on COTS vs. OSS by Morisio and Torchiano in 2002:

3 Norwgian and 4 Italian SMEs. See IEEE Software 2004.

3.3 Attitudes to software reuse in three Norwegian companies in 2002-2003

See PROFES 2003.

3.4 Prestudy from 2003 on COTS usage, autumn 2003:

Forstudie i 2003 som strukturert intervju. 16 utviklere i 13 bedrifter, convenience sample.

Was meant to follow-up a pre-version of the IEEE Software paper from 2004 by Morisio/Torchiano.
This COTS prestudy in 2003 with 16 respondents showed that the COTS integration process involved:

First ask a colleague whether she knows (of) some suitable and well-proven components in use locally.
Otherwise:
First apply plain web-search engines,
then download the most promising candidates,
followed by local trials of these, and
finally decide upon one of these.
Formal evaluation methods are hardly used.
COTS can be applied in almost any lifecycle method, but preferably in an incremental setting including Agile methods.
There is a need to manage and share evolving knowledge about certain components (by a component "uncle").

Innsikter: meget få bruker formell eval.metode, alle bruker initielt nettsøk, kan kombineres med (enhver) forhåndsbestemt utviklingsmodell, trenger komponent-"onkel" for å følge opp en komponent, tradisjonelle kvalitetsegenskaper (pålitelighet osv.) ikkke noe problem i praksis.

Missing: interview guide, transcriptions, ...

3.5 Main survey from 2004 on COTS/OSS usage:

Hovedsurvey i 2004 med spørreskjema-utfylling på webtjener.

Ca. 150 utviklere i Norge, Tyskland og Italia, stratified-random sample. Ekstra innsikter: vanskelig å estimere feilfinnings (f.eks. ligger feil i egen eller importert kode?) og integrasjonsarbeid.
Starter med "vanlig" nettsøk, kan kombineres med enhver forhåndsbestemt utviklingsmodell, trenger komponent-"onkel" for å følge opp en komponent.

Our main OTS study in 2004 (ca. 150 respondents in Norway, Germany and Italy) showed that:

The hardest problems in COTS integration are effort estimation and debugging.
Quality concerns are not serious in practice.
