Replacement of legacy app with off-the-shelf software

Why Do I Need to Modernize My Software?

Top 8 indicators of when it’s time for modernization

  1. Complicated interface

    The software does the job, but users complain about the interface, spend too much time doing trivial things, or cannot locate features.

  2. Performance is unacceptably slow

    The software is functional, but as the number of users grew, or the database became bigger, it started to work unacceptably slowly.

  3. Bugs

    The software is mostly working, but there are bugs the previous team cannot fix.

  4. Self-made prototype

    The software is a self-made prototype. Now you need a “professional” version.

  5. Not finalized project

    The software is partially functional. The team who started on it is unable to continue, or you have decided to replace them.

  6. Old version of CMS

    The software is built on the older version of the CMS. A user wants to benefit from the new features, but custom modules are written in such a way that they cannot be upgraded easily.

  7. New features are needed

    The software is working fine, but needs new features added and the previous team is not available.

  8. Legacy Software

    The software is outdated and needs drastic improvement in a situation where you can’t simply replace it with new software.

Important Facts About Software Modernizaton

What you need to know before you start re-engineering

Analysis comes first

There is specific risk that must be accepted by all parties: we cannot make any estimates or implement anything before we investigate the existing solution and analyze the code. Even after that, there’s still a risk of identifying bugs or unexpected solutions created by previous developers. Addressing them is our job, but this risk exists.

T&M engagement model

Because of the described risk, we offer only the Time and Material engagement model for software modernization projects:

  • payment is based on hourly rates
  • all additional expenses are negotiated before the project start
  • timely project reports
  • control over deliverables

Qualified team

Reengineering can be done only by highly qualified developers with solid expertise in software modernization and knowledge of various technologies. The procedure doesn’t make sense otherwise.

Milestones in Modernizing Legacy Software

Important steps we take:

Analysis

The first and most distinct part of the job is analysis. It is common for the customer to be unaware of the true state of the project, in the belief that only a couple of things need fixing. Therefore, we can test the system against stated requirements and offer a Business Analysis. The deliverables are:

  • functional specification
  • test plan
  • technical specification
  • test report

Project Proposal

On completion of the analysis phase, we are ready to come up with a project proposal and estimate the work that has to be done. The project proposal includes:

  • project assumptions
  • hourly rates of specialists
  • project team
  • timeline
  • detailed project estimate

Software Modernization

In most cases we will offer the Agile development approach based on SCRUM methodology. Development typically runs 30% over the time estimated due to code issues. Depending on the project, typical changes include:

  • User interface transformation
  • Code refactoring
  • Extension of capabilities.

Quality Assurance and Support

Besides standard quality assurance procedures, our team works at integrating modernized applications into your IT infrastructure, and documents everything in sufficient detail and in an easily accessible form for developers and other stakeholders.

  • project Quality Assurance
  • project documentation
  • solution testing
