ERP/Release Life Cycle

Contents

Introduction

This article describes the Openbravo releases in terms of their life cycle and support plan: initial release, maintenance mode and end-of-life.

Release strategy

Generally speaking there are two main release strategies:

  1. Time based cycles: release software with a fixed periodicity. Ubuntu is an example of this strategy, they release a new major version every 6 months.
  2. Feature driven cycles: release software following the "It's ready when it's ready" strategy. Debian is an example of this strategy, they have a quality based criteria for considering a release as stable.

Openbravo uses a mixture between the time based and feature driven release strategies, following a criteria as follows:

Releases

So far Openbravo ERP has released 4 major releases:


Version Maturity status Current release stage Current release frequency Release Date End of life date
3.0 Production ready Preventive Support Quarterly 15/06/2011 undefined (*)
2.50 Production ready Preventive Support on demand 16/04/2009 undefined (*)
2.40 Production ready Discontinued Discontinued 08/10/2008 31/12/2014
2.3x Production ready Discontinued Discontinued 5/11/2007 10/12/2009


Bulbgraph.png   (*): the end-of-life date calculation depends on the second to next major version. For 2.50 this will be calculated once 3.1 is released, and in the same manner 3.0's end-of-life date depends on the future 3.2 release.


Some of the columns require additional explanations of their possible values and meanings:

Stages

ERPs are mission critical software and this is why Openbravo has designed a support plan according to this necessity. This is the root idea from which some additional key requirements flourish with the goal of creating the best possible Openbravo support plan:

Regular Maintenance Packs (MPs) look to increase the stability of the product and fix the customer's issues according to the SLAs. In terms of timings, we have defined 3 stages, explained in detail as follows.

Preventive Support

Preventive Support lasts till the first ship date of the second to next release plus six months with a minimum duration of 30 months (2.5 years) from first ship date:

Minimum duration: 2.5 years.

Reactive Support - Phase 1

Duration: 1 year.
