Decision tree "Agile or Waterfall" using project metrics

Agile Estimating Information Technology PMO

JOSEE DUFOUR IT Programme Manager| Worldline Savigny Sur Orge, ., France

Hi,
As an IT software development organisation, we have various clients for which we deliver many projects, sometimes using Agile (Scrum, XP, Kanban...) sometimes using a waterfall methodology, sometimes using hybrid of both models.

When deciding the method to use it often involve gut feeling, client phantasm of what would be best, team’s desire to perform a project in such way or another… not always based on facts indeed.

We sometimes find ourselves having to switch from one model to another or adapt during the course of the project due to (not exhaustive at all!)
1) Initial project assumptions on scope were not quite right
2) Teams not correctly trained
3) Lack of customer involvement
4) Third party suppliers following their own methodology
5) …

I’d like to create (or use an existing) "tool" that would guide teams (project teams but also pre-sales/bid teams) to select the initial project methodology or to provide arguments to pre-sales teams to convince a client adopting “the best” methodology.

I would like to have kind of a decision tree based on project metrics (project duration, team size, number of stakeholders, co-location/multi-site, customer business type, etc.) known at the time of decision.

Does someone know if that exist?
And I would really appreciate any comments or guidance you might provide!

Thanks in advance

Thanks Gopinath

Your advice is indeed valid, but once the project has started I feel (maybe to adapt the model?). My aim is to help PM select a methodology at project start based on previous projects' metrics, by analogy.
A simplistic example: a previous 3000 man/day successful project was managed in Agile; my project is estimated 3000 m/d, so using Agile will lead to success...
Then adding all known project metrics to the decision tree...

I second This

Hi Josee,

I have not seen a tool but it would be great to have one based on some metrics such as those in this article: https://www.coursera.org/articles/project-...gies-your-guide

In my experience I have seen organizations go with the latest and greatest out there; namely SAFe as of late. I would say it depends on the project... I have seen smaller ones adapt PMP and larger ones adapt SAFe, and those in between hybrid.

Hope that helps and all the best!

Hi Josee,

I am very curious to know if you could come up with a decision tree here. I am in the process of building one myself and any feedback/learning points are welcome!

PMI's Disciplined Agile toolkit is largely focused on Choosing Your WoW (Way of Working) and includes selection guides and decision trees for selecting a project lifecycle model. DA itself is more focused on selecting the right approach such as Scrum, Kanban, traditional waterfall, etc. rather than the details of how to execute specific lifecycles.
