(1) Never Never “Top-down” estimate your Project. Please see Timeboxing IT Projects Parts 1, 2, 3 for definition of “Top-down” & “Bottom-up” planning /estimation and why it is always preferential to develop estimate on the basis of the later.
(2) Never Bully your project team to provide estimates. Do this and you will end up with a CRAP estimate and an unfeasible project to run. Furthermore, you now have a bunch of de-motivated staff who, if things do not work out, will say “I told you so”. Like a Bomber Pilot flying over enemy territory, there’s not much future in doing that.
Encourage project team members to explain their reticence in give estimates through additions to the risk/issue and assumptions logs.

Board 2 – Headed Prerequisite Constraints

Make sure that everyone involved in the product deliverable is present.

• What is Timeboxing?
For those newbie’s to IT Project Management, Time boxing is where a group of tasks are given a fixed period of time to be completed. Time Boxing is often used in project management, not just to set the delivery goals for small groups of tasks, but rightly or wrongly to set the delivery date for entire projects /programmes of work.
• Different Timeboxing techniques
“Top-Down” Timeboxing
The “Top Down” setting of a Timebox is where management dictates what product is produced - where, how, when and with what resource.
“Top Down” is often used at project level by sponsors /clients wanting to set a delivery date for a project of specified scope /quality /cost.
Usually no attempt is made to discover whether such a project is feasible other than a “gestimate” by the senior management and sponsor. At project level I have never seen a top down timebox plan work to time without significant stripping out of scope and quality. Often the descoping has been so aggressive that very often the IT system delivered has failed to remotely achieve its original business case objectives.

My IT Management Philosophy has always been based on four key principals
which I have always considered to be independent of the current ‘flavour of the month’ in terms of IT development /project management methods:-
