Overview
People today are attracted to information systems careers because information technology (IT) can have a dramatic impact on productivity and profits
It is the people who develop information system solutions that harness the power of the technology that makes these benefits possible
The key to successful system development is thorough systems analysis and design to understand what the business requires from the information system
Systems Analysis and Design in a Changing World, 7th Edition - Online Chapter A
Overview (continued)
Systems analysis – the process of understanding and specifying in detail what the information system should accomplish
Systems design – the process of specifying in detail how the many components of the information system should be physically implemented
Systems analyst –a business professional who uses analysis and design techniques to solve business problems by using information technology
This text is about the tools and techniques used by a systems analyst to develop information systems

Problems to be Solved
Need: customers want to order products any time of the day or night. Problem: how to process those orders around the clock without adding to the selling cost?
Need: production needs to plan very carefully the amount of each type of product to produce each week.
Problem: how to estimate the dozens of parameters that affect production and allow planners to explore different scenarios before committing to a specific plan?
Need: suppliers want to minimize their inventory holding costs by shipping parts used in the manufacturing process in smaller daily batches.
Problem: how to order in smaller lots and accept daily shipments to take advantage of supplier discounts?

Wound healing PPT
This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.
How to Fix the Import Error in the Odoo 17
