Agile and Lean transformations depend to a great extent on cultivating a good sourcing ecosystem. The decisions you make around the partners and providers supporting your transformation and projects will be at the core of a successful strategy. But sourcing strategy needs to go beyond just resource or services providers (read outsourcing) and address a larger ecosystem made of Agile SW development and delivery choices, collaboration and communication capabilities for distributed teams, and teams' physical work spaces, standard equipment, and office layout.
In September, I published a report on how to source your Agile strategy, that describes what the ecosystem looks like and how to navigate it effectively, the document is part of our larger research container on Agile - The Agile and Lean Playbook. The report gives an overview on how large vendors, SIs, and medium to small consulting organizations can (not) help you with your Agile journey but also what you need to do to be successful. Here are some of the takeaways from the research:
What you think about Agile and Lean might not be what your SI thinks. You need to take control of your own destiny with Agile and Lean. Change your application development and delivery sourcing strategy to embed the best talents around the world to help you make it happen. But be careful with the traditional SIs, because Agile is as disruptive to them as it is you, and if they have not been seriously transforming themselves, it will be hard for them to deliver Agile services to you. Some good alternative new fully Agile players exist, including highly specialized external consulting firms. You might want to start testing the ground with these options.
