What is ERP? The dream ...
  • Evolved from MRP (Material Resource Planning) in
    1960s
  • A term coined by Gartner, Inc. in 1990s
  • ERP attempts to integrate all departments and
    functions across a company onto a single computer
    system that can serve all those different
    departments' particular needs
  • If installed correctly, it can have a tremendous
    payback!

Current Trends
  • Consolidation in progress at the top end of the
    market due to saturation
  • The SMEs market and developing countries are the
    next battleground.
  • Small to medium-sized vendors are felling
    squeezed.
  • Deploying the next batch of enterprise
    applications, e.g., CRM, SCM, and SEM to generate
    new revenues

Small to Medium-Sized Enterprises (SMEs)
an entity that has less than 250 full time
equivalent employees, and has an annual turnover
not exceeding 50 million, or an annual balance
sheet total not exceeding 43 million, and is not
owned by 25 or more by a non-SME

Why Open Source ERP?
  • Mad science or a big dotcom business opportunity?
  • There is much more to open source software than
    Linux.
  • The availability of open source components, e.g.,
    OS, DBMS, Servers
  • ERP is ubiquitous!
  • Pitfalls of COTS-based systems

First we made games, and they said, "Of course
people will make games for free. But they won't
make anything serious and give it away." Then we
made compilers and developer tools, and they
said, "Of course they will make developer tools.
They're developers. But they won't make anything
serious, like an operating system." So, we made
an operating system, and they said, "Of course
they made an operating system. They studied Unix
in school. But they'll never make applications."
Guess what we're making now? Applications. The
next wave of open source is here.

Survey of Open Source ERP Market
  • SourceForge.net, the largest open source software
    repository
  • Had expected a small number of industrial-strength
    packages
  • But found many low-quality packages 129 in
    total, majority of these inappropriate for an
    industrial use

  • Highly positively skewed (kurtosis 39.05,
    skewness 5.70)
  • Given enough eyeballs, all bugs are shallow.

  • Pearson correlation coefficient rxy 0.20
  • What it must not fail to do is (a) run, and (b)
    convince potential co-developers that it can be
    evolved into something really neat in the
    foreseeable future. Eric S. Raymond

  • It's fairly clear that one cannot code from the
    ground up in bazaar style. Eric S. Raymond
  • rxy 0.26

t-Tests
  • Divided projects into corporate-sponsored ones
    and independent ones
  • Conducted t-Tests w.r.t. no. of developers,
    lifespan, CVS activities, and downloads
  • Not significant statistical differences between
    the means of these two groups
  • Being small, these companies' influences might
    have been minimal.

Chi-Square Test
  • Checked whether each project has released files
  • Qualitative data (Yes/No)
  • df 1, X2 18.46, alpha 0.05, critical value
    3.84
  • Statistically significant

Conclusions and Further Work
  • EISs as the next wave of open source
    applications
  • Fierce competition expected in the ERP market
    geared for SMEs
  • Originating an OSS ERP project in the bazaar
    style is not recommended!
  • New business model for software software as
    service, e.g., consulting, customising and
    maintenance
  • Some SMEs ERP vendors will open their source to
    increase market share.

Conclusions and Further Work(2)
  • Investigating the developers' various
    characteristics, e.g., why do developers want to
    start their own projects rather than joining
    existing ones?
  • Surveying customers' needs Know your
    customers' needs
  • Looking into the evolutionary pattern of OSS ERP
    packages
