How to be Effective?

Any sufficiently advanced technology is indistinguishable from magic
Arthur C. Clarke

Everything what can be digitalized, can be handled for almost  free

So, don't move boxes, move bits

Software Technology Shift


Free (Libre) Software

Free Software movement was introduced by Richard Stallman

Free software guarantees following freedoms to users:

  1. The freedom to run the program, for any purpose.
  2. The freedom to study how the program works, and change it to make it do what you wish.
  3. The freedom to redistribute copies so you can help your neighbor.
  4. The freedom to distribute copies of your modified versions to others. By doing this you can give the whole community a chance to benefit from your changes.

Free Software versus Open Source

Eric Raymond "rebranded" free software as "open source" and proved that:

  • Open source is not only "morally right"
  • It is also more effective software development approach
    To adjust free software principles for business needs, he introduced more "weak" principles:
  • Author can redistribute using different licenses
  • Limited usage of trademarks for derived works

What Open Source Software Provides

  • Low cost
    "Good programmers write code, excellent programmers reuse and rewrite"
  • High quality
    "Given enough eyeballs, all bugs are shallow!"
  • No vendor lock-in
    All software users and vendors are equal
  • Multiple choices
    No tough question about "Buy or build?"
  • Software as a commodity
    Time when software was scarce resource has gone

How Open Source Does It?

  • Resources on demand
    Virtualization allows to prepare resources in minutes
  • No hardware shipment, no tedious planning
    No accountants for tracking license fees
  • Open standards
    Open source is "working standard". Anyone is free to analyze it and check for conformity. That makes integration easier and lowers integration costs.
  • Thin clients
    All that needed is Web browser (in computer, laptop, netbook, phone, etc.). No installation, no upgrades on the client side
  • Low initial investments
    "Fail early, fail often!" Using open source you can easily test/check if software fits your needs and move on

New Business Models

Open source is effective and agile production and distribution approach
Open Source is not technology or business model, but it allows to use advanced business models

  • Freemium
    So called "Open core" as a new shareware. Main functionality is free, but premium services are for money
     Mainstream for Web 2.0 applications
  • Dual licensing
    Open source version is for all, but closed version for those who can't/won't use open source
     Popular for infrastructure applications and tools
  • Maintenance, system integration and consultations
    So called "Pure open source". Popular for new age software vendors

"Software industry is largely a service industry operating under the persistent but unfounded delusion that it is a manufacturing industry."
Eric S. Raymond, "The Magic Cauldron"

Open Source Software for Business

  • Internet clients
    Firefox, Thunderbird
  • Content management
    Drupal, Joomla

Do It Yourself

Barack Obama won elections using slogan "Yes, we can!".
This is true also for you.

You can't be competitive if most of answers from your software vendor are "No, you can't!"

Start using Open Source software. You are not forced to do all yourselves, but if you can, you are not deadly dependent on your  provider.
99% of open source of clients, who start use paid support, are using this software already!

Who Use Open Source?

Open source are using:

  • Your suppliers even though they don't say that
  • Your clients even though they don't know that
  • Your competitors even though you don't now that

Question is not "What does it cost?

Question is "How can we use it?"
