1. What are functional silos and how did they evolve in organizations?
When the organization becomes larger and more complex the functional silos evolved. This happens when the company have different department with different responsibilities, if any department needs anything they work separately with no integrate with other department. 2. What is the relationship between organizational functional silos and IS functional silos?

The two types of functional silos serve the needs of a department but in two different ways. Organizational functional silos are independent unit and the changes that made in these silos not allowed to be shared between other departments. IS functional silo is different because there is no online sharing of data..

3. Compare and contrast centralized, decentralized, and distributed IT architectures. Which do you think is most appropriate for ERP and why?
Centralized systems are based on servers and mainframes, where all the data, software, and resources are stored on the server and are accessed via dumb terminal computers, that is nothing is really stored on the satellite computers. In Decentralized System we have multiple computers with the information and software they need, this gives them full control over what takes place, but may lead to less real time cooperation. Finally, distributed architecture is a combination of both centralized and decentralized architectures with their own applications and tools.I think the most appropriate system for ERP is the distributed architecture because it combine both centralized and decentralized, and boasts better data consistency and integrity.

4. List the horizontal and vertical levels of systems that exist in organizations.
-Vertical Levels of systems (going down)

...Project: Project Part 1: Executive Summary First World Savings and Loan is a financial institution that processes credit card transactions and loan applications online. We are currently considering implementing an open source infrastructure. This could potentially save us over $4,000,000 per year in licensing fees for the software we are currently using. However, due to our business needs; we must still comply with the Sarbanes-Oxley Act (SOX), Payment Card Industry - Data Security Standard (PCI-DSS), and the Gramm-Leach-Bliley Act (GLBA). We must comply with SOX, because we are a publicly-traded financial institution; PCI-DSS, because we process online credit card transactions; and GLBA, because we are a financial institution. All of the regulations of these three compliancy laws must be met, while still maintaining the Confidentiality, Integrity, and Availability (CIA) triad. All security requirements for SOX, PCI-DSS, and GLBA can be achieved using Linux and open source infrastructure. Some examples of open source software that we might use are: Web Server - Apache Web Filtering - DansGuardian Network Firewall - Turtle Firewall VPN - Endian Firewall Community IDS/IPS - Suricata Database - MySQL File Server - Samba SMTP Server - hMailServer I would recommend that we use a "Defense in Depth" strategy, having multiple layers of access protection.

Operations Management - Inventory

...1.1 INTRODUCTION Inventory Management An Inventory is a Stock or Store of goods kept to meet customers expected demand. Inventory can also be defined as the stored accumulation of transformed resources in a process, and it usually applies to material resources but may also be used for inventories of information. Almost all operations keep some kind of inventory, most usually of materials but also of information and customers (Customers inventories are normally called Queues). These inventories can take various forms, which includes raw materials purchased but not processed, work- in- process (WIP) incomplete products or components nor longer considered raw materials., maintenance, repair and operating materials which are supplies necessary to keep machines running and finished goods inventory which are ready to be sold.(Anonymous, 2007) Inventories are costly, as they sometimes tie up working capital. They are also risky because items held in stock may deteriorate, become obsolete, or indeed get lost. Stocks also take up valuable space. On the other hand they provide security in uncertain environments because the operation can deliver stocks should customers demand them. Inventory management in some operations is more than just a part of their responsibility; it is the very reason for being in business (Slack et al 2007). 1.1.2 DISCUSSION The five performance objectives are Quality, Speed, Dependability, Flexibility, and Cost. Quality Many...
