Media tower Tethered gas balloon Poor person’s CN Tower

Media Tower: By Architect Brian Saumure

Downtown Disney

Flies at night In moderate winds Naming rights

Los Vegas World’s largest helium TGB

Original French design

Docking is hard

Birds nest John Davidson

Mooring facility for tethered gas balloon United States Patent 7093790 http://www.freepatentsonline.com/7093790.html

Goes up to 500 feet in five minutes,/hovers there for five more /descends in five minutes…

Takes up to 30 people at a time… Costs ~ $1 million for basic infrastructure… People pay about $30 for round trip…

Does it make any money?

Revenues might look like this:

Helium Airships

CPM or Critical Path Methodology was developed in 1950’s to organize and track numerous activities associated with Polaris missile defense program

Using CPM helps identify and coordinate various tasks associated with completion of project

Allows various information about a specific project to be found including—

--total time to complete to project--scheduled start and finish dates for each task pertaining to

project’s completion--tasks that are ‘critical’ to project and must be completed

exactly as scheduled--slack time available in non-critical tasks, as well as how

long they can be delayed before affecting project’s finish date

Reminders after Lecture 3! Read chapter 10 in Entrepreneurs Handbook II, Advanced

--Develop list of tasks required to complete the project --Make task so purpose is clear/usually best to use two words—verb followed by noun; e.g., build walls, install windows--Define tasks so that they are right size/if task too large in scope, may hide smaller tasks that need to be completed--Turning on cement mixer too finely detailed to be valuable to CPM/this level of detail quickly leads to cluttered and confusing schedule--Tasks should be well defined, precise and detailed but they should also be significant to furthering project

--Order tasks and determine immediate predecessors for each--Identify what tasks need to be completed before next task can be carried out; i.e. the foundation must be completed before walls built

Determine completion time for each task/how long individual tasks take to complete?

Sources for determining these times are: - your own judgment and experience - draw on the experience of others - obtain estimates from professionals

- if you know what something costs in terms of its labor content and you have an hourly wage, you can divide former by latter to arrive at preliminary estimate of task time

CPM–forward pass

Before you begin backward pass to complete flow chart, you need to know that Latest Finish Time (LF) for last task is exactly equal to the Earliest Finish Time (EF) for the last task

This is an identity

Gantt chart = bar chart developed by Henry Gantt in 1910s illustrates project schedule illustrate start and finish dates of terminal elements and

summary elements of project
