The difference between Complex and Complicated Projects

The world if full difference when we talk about complex projects. Is complexity the same as complicated? By complex do we just mean a large project, one which is geographical distributed or using complex technology? Or are these mega project just more complicated.

What is meant by a complex project?

Within business complexity is defined as
“Complexity describes the variances in approach and their consequences on the business”



I think complexity is closely related to ambiguity of project goal and method of delivery, because complexity is caused by the challenges of planning the project in the first place and likely level of anticipated change. This complexity makes it impossible to sit down and plan the project in a clear way from start to end; we need a slightly more flexible approach to the traditional “plan the work” “work the plan”. This can be represented by an adaptation of Rodney Turners classic goal method matrix

The higher the levels of ambiguity about the project goal and uncertainty about the delivery method make it more difficult to manage in a traditional way. This seems more important than the pure size of the project. Some large complicated projects have clear goals and known methods and these can be managed in a very traditional way. This definition differs from the normal multi organisation; multi-phase definition defined by the APM, but is nevertheless more relevant to help think about the complexity of the projects we manage.

  1. Complexity is not about the structure of the project (or at least complexity theory is not) complexity is about the unpredictability of the effect of any conversation or stimulus within the relationships that crate the project team and their surrounding community of stakeholders. From the perspective of complexity theory and CRPR every project is complex. All that changes is the degree of complexity.
    Complicated is a solvable engineering problem.

  2. Dear PNaybour
    I LOVE IT!!!
    I’m reminded that it’s no coincidence that Howard Schultz and Jim Donald are smart, proactive, visionary leaders. Starbucks is such a great company because its collective IQ and knowledge are off the charts!
    But in the midst of the tough economy, there’s a lot of bashing and cynicism towards change, performance recognition and, inspirational efforts in the workplace. Just check any bar in lower Manhattan! It’s a shame.
    As a VP leading over 100 salespeople, I’ve found that the hard fact is that QUALITY performance recognition works. Not just for morale, but in dollars. I have been using a
    couple of different tools to help me retain good people and to inspire excellence in them,
    which = larger sales figures. A#1 tool is a personal, elegant recognition concept called Design Your Inspiration (www.dyi.successories.com ) .
    Intelligent, customizable with any words and/or great quotes you want to use (such as those on this very site!) All on framed, art photography prints.
    Again, the quality of these, and the MEANING emparted, makes them highly effective for me.
    It has made an amazing difference! So while the cynics shed tears in their beers, we’re laughing all the way to the bank! Thanks again. Jim
