Parameters
Subcontract
• Add extra 20% to cost of labor
• Not need pay set-up fee or commit to minimum order
Design Change
• Cost $15,000 one time charge & take 1 month to implement
• Only applicable to CloudChair Product
Part 2 | Problems Identification
Considerations
Overtime
• Overtime wages were 1.5 time s the normal fully loaded rates
• Introduced fatigue, leading declines in quality
Constant Worker Vary Inventory
High inventory or Shortage of product
Hiring & Layoff
Doesn’t Compatible with Company’s Goals
3PART 3The Theories
Sales and Operations Planning
Process should help firms to provide:• Better customer service• Lower inventory • Shorten customers lead times • Stabilize production rates • Give top management a handle on the business.
Part 3 | The Theories
Aggregate Operation PlanThe main purpose of the aggregate plan is to specify the optimal combination of: • Production rate• Work forces level• Inventory on hand
PURE STRATEGIESChase Strategy:
Hiring and laying off employees as the order rate varies
Stable workforce-variable work hours:Vary the output by varying the number of work hours worked through flexible work schedules or overtime
Level Strategy:Maintain a stable workforce working at a constant output rate
MIXED STRATEGYIf two or more strategies used in combination

PRO CONS
1. Cost. It is profitable
2. Sustainability; can meet demand if the demand continuous to increase
3. No need to train; the workers can perform well from the start
1. Demoralization; future lay off of superfluous labors may demoralize other workers
1. Sustainability; can meet the demand if demand continous to increase
1. Cost; management and supervisor resources
2. Subsequent result; layoff these new workface and cost the company in added unemployment insurance
3. Time; training unskliled workers to skliled position takes four weeks

Demand forcast per month:
Ending inventories
Safety stock
Excess (shortage) of inventory
Cost of excess of inventory
Problem Analysis Constant Level of Production
1. producing above the demand may result in high inventory level
2. There are cost of carrying inventory
3. When demand was very high but production constant may result in shortage of product
PROS1. Labour work in a constant time,
produce the same amount per day makes labour on high productivity and avoid fatigue
2. Utility of machine easily measure3. Furniture design likely to change in
long period4. Keeping inventory in some level help
Foldrite for fast delivery
Recomendation :By calculating existing labour based on December 2009 data, Foldrite must add labour to produce constant level of product without overtime to fulfill demand forecast for the year of 2010. Cost of additional labour and do constant level of production, although result in vary of inventory level still below the cost of do nothing (not add worker, no overtime, no training, no subcontracting and no change in design)

Production requirement
Unit subcontract per month:
Cost of excess subcontracting
Problem Analysis Subcontracting
1. Get the job done right and on time
2. Don’t need to spend money on recruitment and training
3. Can have relatively flexible change according to the demand
1. Inventory cost and extra to the cost of labor for the product.
2. Finding the right subcontractor can be difficult
3. Communication can be problematic
4. Difficult to maintain the quality of product

Demand forcast per month:
Unit available before overtime
Overtime unit
Beginning inventory
Production requirement
Problem Analysis Overtime
1. No need to lay off the superfluous labors and thus suffer from the demoralization and high unemployment insurance after the surge in demand
2. Flexibility: can make change according to the change of the demand
PROS
1. High cost: overtime wages were 1.5 times the normal fully loaded rates.
2. Decline in quality and yield: overtime may lead to labors’ fatigue
3. Potential risk: may not able to meet the demand if the demand continues to increase
4. Negative effect on potential labors: the long-lasting overtime may discourage other labor join in the company

Conclusions
• FoldRite goal to reduced turnover of work force aligned with stable workforce strategy. To be a lean manufacturer which has flexibility to response specific customer requirement, the company could adopt level strategy.
• Demand variations are high for CloudChair product, so the planning system must include sufficient flexibility to cope with, that can achieved by cross-training worker to handle a wide variety of orders, developing alternative source of supply, and engaging in more frequent replanning during high-demand periods.
• Chasing strategy at Plan 1 with target production to fullfilldemand requirement using flexible workforce by hiring, training, and layoff labors seems to be suffer with layoff cost and this also doesn’t compatible with FoldRite goals. Design change did not siginificant lowering cost (only 1 minutes improvement for CloudChair product). Other alternative planning are more suitablewith FoldRite strategy to achieve 4 goals.
• Relationship with among various functional unit, including marketing is a key of success to manage production planning.
Recommendations
• More production for CloudChair since it has greater contribution margin and lower cost of production and cheaper product line.
• Keep planning strategy aligned with company goals by choosing stable workforce and level strategy. For seasonal product, it’s more efficient to have constant of labor and subcontracting the rest of demand. This could affect to lower employee turnover also, managing quality of product and lowering inventory fluctuation.
• By calculating existing labour based on December 2009 data, FoldRitemust add labour to produce constant level of product without overtime to fulfill demand forecast for the year of 2010. Cost of additional labour and do constant level of production, although result in vary of inventory level still below the cost of do nothing (not add worker, no overtime, no training, no subcontracting and no change in design).
• The usage of MRP, ERP, SCM, and other IT related system to improve production planning quality.
Lessons Learned
• Cost reduction initiative for labor cost will not give significant effect if the labor portion only small amount of overall cost structure. Reduction of material cost has more impact on cost reduction since it’s has 6 time larger than labor cost.
• Seasonal effect of CloudChair should compensate with other product that has opposite seasonal effect to reduce risk of materialized demand.
