At Delta Insights, we use a two-pronged approach offering high-quality, cost-effective solutions, and fast implementations.

Methodology

Agile or Waterfall? Why not both?!

Project Management experts have been divided between following the Agile or the Waterfall methodology. Advocates from each generally praise their chosen methodology’s PROs and all too often neglect to mention the CONs.

 

At Delta Insights, we acknowledge that both methodologies have their strengths and weaknesses. As a result, we adopted a hybrid model to provide clients with the very best of both worlds. Also, we work with clients to ensure that they are confident in taking ownership. We do this by encouraging collaboration from the start and throughout the entire implementation.

 

Combined with thorough testing and continual data migration cycles, we provide clients with the best possible solution for their business using the quickest and most cost-effective methods.

DELIVERY METHODOLOGY

Agile vs Waterfall: Client involvement and visibility

Agile

Created for product / software development.


Breaks up the work into smaller and more manageable parts (Sprints):

  • All work (analysis, design, development, testing, bug-fixing, release) happens within a Sprint.
  • Fixed duration: 2-4 weeks.

Faster visible results.


Not suitable for large complex system implementations with multiple process and system dependencies.




 

Delta Insights

Shorter analysis stage:

  • Focuses on the critical business processes.
  • Design is done in the system: Client users are involved hands-on using the product.

Breaks up the tasks into smaller and more manageable parts

  • Iterations.
  • Multiple Sprints:
    • Sprints are Process-driven.
    • Data Migration Sprints.
    • Reporting.
    • Test Cases.

More manageable deliverables


Integrated Design and Development

  • Less customisation decisions up front.
  • Customisation decisions are made after testing and with use of the customer data (Development only where necessary).

Waterfall

Originally created for large system implementations.


Longer analysis stage:

  • More in-depth analysis.
  • Identifies all the gaps and customisations needed.
  • Design is done “on paper”, without hands-on experience by the client.

Design decisions are made on subset of data and not an end-to-end business process list and exercise.


Delay of user hands-on involvement, until Design and Development is completed.


Potential for requirements to be missed until after design begins.


Reduced flexibility as project enters development phase.
