This table contains the performance criteria and scores (larger numbers are better) for four potential suppliers to Satriale's Pork Store. Evaluate the data and identify the BEST source for Satriale's

Answer: Company P has the highest score, 3.8, and would be the supplier of choice
ScoreX =
ScoreT = 0.4 × 4 + 0.3 × 4 + 0.2 × 2 + 0.1 × 3 = 3.5
ScoreC = 0.4 × 4 + 0.3 × 3 + 0.2 × 1 + 0.1 × 5 = 3.2
ScoreS = 0.4 × 2 + 0.3 × 5 + 0.2 × 4 + 0.1 × 5 = 3.6
ScoreP = 0.4 × 5 + 0.3 × 2 + 0.2 × 5 + 0.1 × 2 = 3.8

Company S is two-tenths behind Company P, and has an abysmal innovation score to thank for this position. If the innovation factor is based on new product or service lines, then Satriale's might request that Company S consider exploring new products more aggressively. Company T is only three-tenths behind Company P, and is slightly behind in the Innovation factor but far behind on the Stability factor. An increase of 1 point in the stability score raises the overall score of Company T by two tenths, so whatever Company T can do to become more stable should be considered. Satriale's might take a partnership stance, perhaps increase the frequency of meetings in order to help Company T in the stability arena. A single digit increase in Innovation raises a score by four tenths of a point, but Company T has a high score already in this area. It might be easier to raise an extremely low score (Stability) than squeeze another point higher in an area where they are already performing well.

How do you determine the number of communications channels? How does the number of people involved in a project affect this value? How can project managers control this value?

An important aspect of information distribution is the number of people involved in a project. As the number of people involved increases, the complexity of communications increases because there are more communications channels or pathways through which people can communicate. There is a simple formula for determining the number of communications channels as the number of people involved in a project increases. You can calculate the number of communications channels as follows:

number of communications channels = n(n-1)/2

where n is the number of people involved.

For example, two people have one communications channel: (2(2–1))/2 = 1 . Three people have three channels: (3(3–1))/2 = 3 . Four people have six channels, five people have ten, and so on. As the number of people communicating increases above three, the number of communications channels increases rapidly. Project managers should try to limit the size of teams or sub teams to avoid making communications too complex.

Discuss the primary objective and operational parameters of aggregate planning

Answer: The goal of aggregate planning is to satisfy demand in a way that maximizes profit. Aggregate planning is a process by which a company determines levels of capacity, production, subcontracting, inventory, stockouts, and even pricing over a specified time horizon. The aggregate planner's main objective is to identify the following operational parameters over the specified time horizon:
• Production rate: the number of units completed per unit time (such as per week or per month).
• Workforce: the number of workers/units of capacity needed for production.
• Overtime: the amount of overtime production planned.
• Machine capacity level: the number of units of machine capacity needed for production.
• Subcontracting: the subcontracted capacity required over the planning horizon.
• Backlog: demand not satisfied in the period in which it arises but carried over to future periods.
• Inventory on hand: the planned inventory carried over the various periods in the planning horizon.

The aggregate plan serves as a broad blueprint for operations and establishes the parameters within which short-term production and distribution decisions are made. The aggregate plan allows the supply chain to alter capacity allocations and change supply contracts.
