AGENDA Critical Chain Project CRITICAL CHAIN Chapter 1 Main characters Plot summary Chapter 2 Main characters Plot summary PROJECT A series of connected homework projects Application of most of the concepts covered in class Groups Size 5 PROJECT BACKGROUND Conduct all the necessary project activities to build a one-off custom designed mid-sized cruising sailboat Determine What type of sailboat project to undertake Identify what components are needed Identify what resources are needed Determine the project plan including sequencing Perform budget and cost estimation Identify a means of monitoring the project progress Etc. Will need to use the Internet to perform project research HOMEWORK #1 PROJECT SELECTION Select type of sailboat project to undertake… By evaluating on project selection factors… Using one project selection model… SELECT TYPE OF SAILBOAT PROJECT Required features… Project design decisions… REQUIRED FEATURES Must be off-shore cruising capable Can make extended voyages over oceans Category A Required systems Fresh water system Sanitation system – Toilet and shower Cooking facilities – stove Electrical system – lights, instruments etc. Air conditioning and heating REQUIRED FEATURES PROJECT DESIGN DECISIONS Size… Rig design… Hull material… Hull design… Propulsion… Many other design decisions, but we have to draw the line somewhere SIZE Sailboats are measured by overall hull length and width (beam) The longer the boat, the wider the beam Every five feet, the effective volume doubles Forty foot boats are actually twice as large as 35 foot boats Popular sizes of these types of boats 36, 38, 42, 44 Bigger is more expensive to buy and cost more to maintain RIG DESIGN The rig consists of The masts The sails Supporting wire stays Designs in order of complexity Sloop – 1 mast with one headsail and one mainsail Cutter – 1 mast with two headsails and one mainsail Ketch – 1st mast with one headsail and one mainsail, 2nd mast with mizzen sail Flexibility under adverse conditions Sloop < Cutter < ketch Cost Sloop < Cutter < Ketch RIG DESIGN HULL MATERIAL Fiberglass Cheapest material and easiest to make Blisters, but does not corrode Easy to repair Aluminum Most costly material and most difficult to make Does not blister, but can corrode Difficult to repair Steel More costly material and more difficult to make Heavy – can only build larger boats Does not blister, but corrodes Easy to repair HULL DESIGN Fin Lighter weight Lesser stability More maneuverability Poor protection against grounding Modified Fin Full Keel Heavier weight Greater stability Less maneuverability More protection against grounding HULL DESIGN PROPULSION Most sailboats have diesel engines Yanmar, Volvo, Perkins, Westerbeke, Vetus HP Appropriate for the boat size Drive method Shaft – more expensive to install cheaper to maintain Sail drive – cheaper to install more expensive to maintain Fuel tank size Bigger diesel engines costs more and uses up more fuel PROPULSION DRIVE METHOD BY EVALUATIONG ON PROJECT SELECTION FACTORS TABLE 2-1 Production Backyard Marketing Both price and quality conscious Must meet offshore requirements Finance Self-investing Personnel Unskilled Administrative OSHA USING ONE PROJECT SELECTION MODEL Non-numeric - not recommended Numeric - recommended
