The impact of planning on project success

February 22, 2016 Pavel Aramyan

“The project was a success!”

This is the dream quote for every PM.

So much time, effort, energy and resources invested into zillions of projects every year, and yet the “dream quote” is rarely uttered. In fact, the statistics are  rather disturbing. 2015 reports show that:

  • 70% companies had at least 1 failed project during the year

  • On average, companies lose $109M for every $1B invested in projects. That’s a monstrous 11% of a truckload of cash poured into nothingness

  • Average project success rate was 39% (defined: delivered on time and with required features)

This doesn’t look very inspiring. And there is this other thing: what exactly is the definition of project success? Is it like we are happy with our job? Does it mean the client is happy? Or both? What about shareholders? Are they happy as well?

In the above report, success is measured by providing the deliverables on time and having the required features. That seems incomplete though. There should be more to it. Each PM has an example where project goals were not even near to getting met, yet the client was highly satisfied. The exact opposite example is also true: All the project goals were met, but the client was rather unhappy to say the least.

So before we go on, let’s first answer the question:

What the hell is project success anyway?

To define project success we will need to take into account a few things:

  • Project efficiency (the goals are met)

  • End user benefit (the client is happy)

  • Business growth (we are happy)

  • Business vision (future seems a little brighter)

Dr. Terry Cooke-Davies, a recognized thought leader on project success, says that there is a direct correlation between all factors and a big difference between the terms “project success” and “project management success”.

Therefore we need to have two definitions: Project management success, which is basically delivering quality stuff in due time with all the requirements (in other words, project efficiency) and project success, which is a much wider thing.

“Project management success is the art of meeting goals and objectives, delivering the promised quality in a timely manner, without creating additional costs.”

“Project success is the positive outcome of different, interrelated actions and events that contribute to the satisfaction of all involved parties.”

This should be a more accurate interpretation. Now let’s proceed and see how planning can contribute to project efficiency and project success.

Be careful with details

Although planning is an essential step in project management, too much detailed planning might not be the best idea.

For example, how can you plan ahead for something in detail, when there is stuff that depends on some other stuff or the results of an action are unclear? Well in theory, you could make use of astrological clairvoyance or crystal balls, but both of these methods have proved to be a little ineffective.

There is another problem too. Sometimes a project can evolve in a way that no one ever thought it would (for instance, client gives you a call and asks to make a tiny adjustment to the product, which appears to be enough to mess everything up) and suddenly you find yourself in a situation where you spent a ton of resources on creating a detailed plan for every phase of the project, which is a little shy of useless now. Something tells me that this isn’t how you want to spend your budget.

Detailed plans also limit your creativity and the ability to respond to change well, especially when you’re using an agile methodology. But starting a project without a plan is like going on an adventure to the Amazon jungle without a map or preparations. Chances that you will survive get slimmer every day.

This is why it’s a good idea not to get into micro details all the way down. Think of your plan more as a guide than a step by step Lego instruction of how to build a gigantic truck. Because if you accidentally lose a single Lego brick, your whole truck might instantly turn into a much less attractive truck.

Okay, so what?

If that’s the question you were thinking, then we are on the same page. Planning is by all means the cornerstone of any project: it’s the king, the master, the god. Don’t get me wrong.

The point is that too much detail might seem to be a good thing, but you will need to have extraordinary luck, a ridiculously efficient team and a perfect client that never has objections or changes his mind.

Since you’re never ever getting this combination in this life (like…ever), it’s better to leave some room to improvise.

I bet now you’re thinking “how much exactly should I spend on planning then?” and here comes the bad part (come on, you should be used to this by now).

There is no right answer here. There are way too many variables that need to be taken into account, including industry, project, client, team, budget, experience, available tech and a whole bunch of other stuff.

The best advice would be to plan based on facts and experience: If you know what works and what doesn’t for a particular case or industry, you should trust your instincts. If you find yourself in a completely new environment, it’s best to keep your expectations low and proceed cautiously, leaving lots of room for improvisation and emergencies.

We are almost there

planning in PM

While it’s close to impossible to clearly define how much effort and time you should dedicate to planning, there is an average number, kinda. This study has complied different researches and facts provided by world class PMs and deciphered a range when resources spent on planning positively affect project efficiency and success.

Just in case you aren’t willing to spend about 2 hours (like I did) trying to figure out how they found the average, here it is:

Putting together all the data assembled from 10 different sources regarding project success and efficiency defined by the factors mentioned above, the average R square (which is the correlation, btw) was calculated for each case.

The overall average R square resulted in 33%, which correlates with efficiency by 33% and 34% with project success.

This means that on a slightly larger average, 30-35% of overall project efforts (including time and budget) should be spent on planning to maximize both project efficiency and project success.

There you have it. Only thing I’d like to add is that while this is a statistic that can be trusted, you shouldn’t always assume it’s true. What works in one case, might not work in another. You know this better than anybody.

The major takeaway from all of this should be the following:

  • Planning is the cornerstone of any project

  • Too much detail will often do more harm than good

  • On average, 30-35% effort should be invested into planning for an average project

  • Everything concerning planning is potentially subject to change

  • Witch balls are unreliable means for future forecasts

  • You should finish your coffee, it’s getting cold

  • Enjoy your day -)Project management methodologies best practices
