Why Things Don’t Add Up

6 years 5 weeks ago

Last time we learned about Continuous Distributions and how they are described by the Frequency Function.  I also promised to save us from the infinitesimal probabilities represented in the Frequency Function. 

The answer is the Cumulative Distribution Function (CDF), which is merely the area under the frequency function curve to the left of a

Distributed -v- Consolidated Contingencies

6 years 5 weeks ago

Distributed contingencies are normal in most aspects of project management but often result in sub-optimal use of resources. Typical examples include allowing some safety margin in each CPM duration estimate (eg, setting the durations at an 80% probability), allowing contingencies on a project by project basis for risk, setting budgets with a 90% confidence limit, etc.

Scheduling For Effect

6 years 9 weeks ago

As the end of 2012 approches, and assuming the world won't end of the 12/12/12 I have a few thoughts for every scheduler’s New Year resolutions.

  1. You can’t change the past, the present is being managed by the project workforce, the only thing you can influence with your schedules is the future. To achieve this, the schedule needs to be an

My Project Is Making No Progress!

6 years 10 weeks ago

I had a situation recently where a client stated that despite his people working as fast and seemingly efficiently as they could, he was seeing next to no progress reflected in his performance reporting, his end date was pushing out, his efficiency was down, people were asking questions.

Now, it's not uncommon to see under staffed or under resourced projects falling

The CPI Stability Myth

6 years 11 weeks ago

Undoubtedly the longest running ‘urban myth’ in circulation within the general project management community, arising from US Defence based research from the early 1990s, that the Cost Performance Index (CPI) always stabilizes at the 20% completion and the final outcome will be within 10% of this value and usually worse. This myth has been extended by some authors to all projects in all

"The Project Must Be Finished On This Date - Or Else!"

6 years 12 weeks ago

These are words of desperation, a client or senior manager who's got his back to the wall.

I was faced with this exact situation on a consulting job a few weeks back, the business owner, facing heavy penalties for late delivery was desperate for answers and didn't know a better way to react.

Unfortunately, what he hoped were a matter of weeks to completion, in

A though on PMOs and Project Controls

6 years 13 weeks ago

The quality guru W. Edwards Deming said ‘In God we trust, all other bring data’. However, developments in the Victorian Government health system (Australia) offer a salient reminder to any PMO manager on the value of data.

Victorian hospitals are rewarded for good performance and fined for poor performance. One measure being the length of waiting lists

Good Planner - The foundation

6 years 13 weeks ago

It is failry common to come across lots of people in planning who are actively engaged in planning but have never visited or worked on the site. This is deeply disturbing. It also applies to other industries as well as you must have noticed. Well, in any case, I belong to the Construction industry and have come across a number of people, at all levels, who may have walked into the construction

Let Us start Planning

6 years 15 weeks ago

A long time back, late Seventies to early Eighties, it was quite a fun to prepare Plans and programmes for Projects. It used to be challenging, creative effort involving lots of hard work but quite satisfying and enjoyable. This went on for quite sometime and this area generally there was no intrusion. Gradually I have seen intrusion in this space by others to the extent that there is no more

One Contractor + One Employer + One site + Two Contracts = Disaster

6 years 15 weeks ago

The situation where a contractor has been awarded two or more different contracts for different phases on the same site must be failry common because I have encountered it three times so far in my career.

It is a recipe for disaster for the Employer because if the contractor causes a delay on Contract 1 which then delays acces to Contract 2 then the same
