Question 1: (5 Marks)

Consider a garment manufacturing company is newly launched and wants to introduce IT infrastructure in the

organization. Suggest what IT infrastructure will be required for the company to fulfill its requirements.

Solution:-

Building a 'world-class' infrastructure ALWAYS starts with the organization structure. Below are recommended organization structures designed for small, medium, and large infrastructure development and support organizations. No one structure is correct; however, it is crucial that key functions be structured to address the people and process issues. These structures are designed to address the people and process issues first with technology being secondary. I'm not saying technology isn't important but let's be blunt here based on the 100 plus assessments For Infrastructure organizations to become successful and cost effective service providers the focus needs to be Organization, People, Process, and Technology in that order.

As I designed these organization structures I included first-, second-, and third-level support roles for each of the areas. I highlight this in the organization charts below because it's one of the most critical functions that was abandoned as IT organizations transitioned to client/server. It happens to be one of the biggest reasons RAS doesn't exist in 95% of the IT shops I have visited Organization structure #1 below is designed for IT infrastructure development and support organizations with fewer than 50 employees. The reasons I designed the structure in this manner are:

> Production Control is at the enterprise level for process design, ownership, and accountability. In every small (.com or emerging e-commerce) company I visited priority is always technology, technology, technology. Although this is a small shop it's never to early to start focusing on processes. I'm not trying to change that priority after all it's what IT is all about-providing Information Technology. We're asking you to think about process. Once the technology is implemented without the processes high availability for that technology is unrealistic.

> Mission critical (Data Center) functions are separated from non-mission critical functions (Desktop, Help

Desk).

> Level 1, 2, and 3, technical staff for the mission critical production environment is grouped under the same organization to effectively breed future technical resources. All IT organizations have a shortage of technical resources but more so in smaller IT shops. 

Organization Structure #1 (for smaller IT organizations)

Organization structure # 2 below is designed for IT departments with 50 to 75 employees. The significance of

this structure is:

> The Production Control function is structured at the enterprise level bringing visibility and accountability

> Service Center (Help Desk) is structured at the enterprise level.

> All mission-critical technical related services are grouped under the Technical Services organizaion.

Organization Structure #2 (for mid-size IT organizations)

Organization structure # 3 below is designed for larger IT departments with 75+ employees. The significance of this structure is:

To introduce an Infrastructure Technology Consulting group. This group's primary focus is designing and developing those special utilities/tools to improve the effectiveness of your infrastructure.

Organization Structure #3 (for a large size IT organization)

Question 2: (5 Marks)

Is Just-in-time (JIT) approach helpful in reducing the production cost in any manufacturing organization? Justify your answer with suitable reasons in either case.

Solution:-

JIT has been defined in several ways, including the following:

1. As a production strategy, JIT works to reduce manufacturing costs and to improve quality markedly by waste elimination and more effective use of existing company resources.

2. A philosophy based on the principle of getting the right materials to the right place at the right time.

3. A program that seeks to eliminate nonvalue-added activities from any operation with the objectives of producing high-quality products (i.e. "zero defects"), high productivity levels, and lower levels of inventory, and developing long term relationships with channel members.

At the heart of the JIT system is the notion that waste should be eliminated. This is in direct contrast to the traditional "just-in-case" philosophy in which large inventories or safely stocks are held just in case they are needed. In JIT, the ideal lot size or EOQ is one unit, safely stock is considered unnecessary, and any inventory should be eliminated.

Many firms have successfully adopted the JIT approach. Companies in industries such as metal products,

automobile manufacturing, electronics, and food and beverage have implemented JIT and realized a number of benefits, including:

1. Productivity improvements and greater control between various production stages.

2. Diminished raw materials, work in process, and finished goods inventory.

3. A reduction in manufacturing cycle times.

4. Dramatically improved inventory turnover rates.

In general, JIT produces benefits for firms in four major areas: improved inventory turns, better customer service, decreased warehouse space, and improved response time. In addition, reduced distribution costs, lower transportation costs, improved quality of supplier products, and a reduced number of transportation carriers and suppliers can result from the implementation of JIT.

Problems Associated with Implementation JIT

It has some inherent problems which fall into three categories: production scheduling (plant), supplier

production schedules, and supplier locations.

When leveling of the production schedule is necessary due to uneven demand, firms will require higher levels of inventory. Items can be produced during slack periods even though they may not be demanded until a later time, finished goods inventory has a higher value because of its form utility; thus, there is a greater financial risk resulting from product obsolescence, damage, or loss.

However, higher levels of inventory, coupled with a uniform production schedule, can be more advantageous

than a fluctuating schedule with less inventory. In addition, when stockout costs are great because of production slowdowns or shutdowns. JIT may not be the optimal system. JIT reduces inventory levels to the point where there is little if any safety stock, and parts shortages can adversely affect production operations.

Supplier production schedules are a second problem with JIT. Success of a JIT system depends on suppliers' ability to provide parts in accordance with the firm's production schedule. Smaller, more frequent orders can result in higher ordering costs and must be taken into account when calculating any cost savings due to reduced inventory levels. When a large number of small lot quantities are produced, suppliers incur higher production and setup costs. Generally, suppliers will incur higher costs, unless they are able to achieve the benefits associated with implementing similar systems with their suppliers.

Supplier locations can be a third problem. As distance between the firm and its suppliers increases, delivery times may become more erratic and less predictable. Shipping costs increase as less than truckload (LTL) movements are made. Transit tune variability can cause inventory stockouts that disrupt production scheduling; when this is combined with higher delivery costs on a per unit basis, total costs may be greater than the savings in inventory carrying costs.\

JIT II applies JIT concepts to the purchasing function by having a representative of the supplier locale at the buying organization's facility. Developed by Bose Corporation, this approach improves mutual understanding

between the buyer and supplier, reduces waste and redundancy of efforts, improves supplier responsiveness, and creates a positive working environment.
