Study Notes

Introduction to the Department of ICT

The document is from Akaki Polytechnic College's Department of ICT.
The subject is Hardware and Network Servicing Level II.

Unit One: Prepare for Work - Preventing and Eliminating MUDA

Occupational Safety and Health (OSH), also known as Workplace Health and Safety (WHS), is an area that handles the safety, health, and well-being of workers.
OHS requirements, safety equipment, and tooling are covered.
Protective clothing, tooling, and workplace safety are included.
Handling of materials, fire-fighting equipment, and first aid are factors.
Hazard control and hazardous materials are included.

Types of Hazards

Biological hazards include bacteria, viruses, insects, plants, animals, and humans.
Chemical hazards depend on the chemical's properties.
Ergonomic hazards include repetitive movements, improper workstation setup, poor equipment design, and manual handling among others.
Physical hazards include slippery floors, unsafe machinery, excessive noise, poor lighting, fire, radiation, magnetic fields, and pressure extremes.
Psychological hazards include shift work, workload, dealing with the public, harassment, discrimination, threat of danger, constant low-level noise, and stress.

Safety Equipment and Tools

Safety is a state of controlling hazards and conditions leading to physical or psychological harm.
Safety involves creating a peaceful and equitable environment protecting human rights.
Prevention and control of accidents and harm are part of safety management.
Respect for individual physical, material, and psychological integrity is crucial.
Specific safety equipment like dust masks, safety goggles, gloves, workwear, first aid, and safety shoes are listed.

Work Instructions

Work instructions include crucial information needed by workers to perform their jobs.
These instructions outline the tasks and activities expected within an organization.
This includes different work functions, key tasks, and performance indicators.

Job Requirements

A job is a piece of work, especially a task, performed as part of one's occupation or for an agreed price.
A job can be full-time or part-time.
It refers to a responsibility or duty; an affair, matter, occurrence, or state of affairs.
The material, project, assignment, or process is also part of a job description.

Job Requirements (Continued)

Discipline is essential for completing any job.
Enthusiasm is crucial for work and job satisfaction, which is a positive feeling toward one's job.
Job qualifications can include degrees or certificates.
Soft skills, like communication and other skills, are also important job elements.

Procedures vs. Work Instructions

Procedures describe a process, while work instructions describe the actions for the procedure.
Key elements of procedures include: Where inputs come from, where outputs go, who performs what action when, how to determine if the procedure was done correctly, feedback to be captured regarding the procedure, how to communicate the results, and what laws or regulations apply to the procedure.

Working Manual and Job Specification

A job specification is a statement of an employee's characteristics and qualifications necessary for satisfactory job performance.

Best Practices for Choosing Materials

To choose the right materials, understand your design's critical components and mechanical integrity.
Familiarize yourself with the materials involved in your design.
Validate your mechanical design.

Unit Two: Muda and its Problem

Muda is a Japanese word for wasteful activity that uses resources, time, or cost without adding value.
Muda is anything unnecessary in operation that affects product/service quality, productivity, delivery time, and production cost.

Types of Muda

Overproduction is producing more than necessary in terms of type, time, and volume.
Inventory refers to raw materials, work in process, or finished goods that remain stagnant.
Motion involves non-value-added or unnecessary movements of workers, equipment, or machines.
Conveyance/Transportation includes unnecessary transportation of parts between processes.
Waiting/Idle time includes worker or part waiting for a machine to finish processing, for incoming parts or materials, or for processes with long wait times.
Defect making involves defects, inspections, rescheduling, and resource loss in process.
Processing involves unnecessary processing beyond what is required for the customer.

Concept of Planning

Planning is the most fundamental function in management
It is a pre-determined outline of activities conducted within an organization.
This involves the process of determining when, what, where, and how an activity should be performed.

Visual Management Board/Kaizen Board

Kaizen Visual Management Boards are visual communication tools crucial for teams and organizations
These tools support the management of continuous improvement efforts and accelerate improvements.
The boards ensure the progression of ideas from "to do" to "done".

Benefits of Implementing Visual Management

Improved workplace productivity and decreased downtime are among the benefits.
It helps impress customers by showing a company's commitment to continuous improvement.
It highlights waste reduction as a daily concern through visual management.
The use of visual management promotes company values as part of the workplace culture.

Relevant Procedures for Wastes/Muda Identification

Identifying Muda helps cut the hidden cost of production by 80%.
It eliminates non-value-added activities or waste which results in increased customer satisfaction.

Contributing to Improvement

Employees' ideas for job improvement are listened to and considered.
Employees participate in mitigating workplace frustrations.
Steps for identifying waste involve recognizing and measuring the waste.

Shop Layout Analysis and Process Flow Analysis

Tools for analyzing current conditions of shop layout and process flow to quickly and effectively identify waste are used.
Arrow diagrams focus on good flow to identify waste (can also be called value stream maps).

Steps for Creating Arrow Diagrams

Understand the purpose of the arrow diagram as a tool for identifying waste.
Select your process or product for analysis.
Prepare a factory layout diagram to help visualize the flow.
Create an arrow diagram with defined symbols (retention, conveyance, processing, and inspection).

Summary Chart of Flow Analysis

A summary chart can be used to document before and after improvements of a flow analysis.
Relevant data regarding the changes in flow analysis can be recorded in this summary chart.

Reading Assignment

Relevant documents like operations analysis tables, standard operation charts, and workshop checklists are useful references for studying major waste finding.

5S

5S is a workplace organization method that uses five Japanese words: sort (seiri), set in order (seiton), shine (seiso), standardize (seiketsu), and sustain (shitsuke).
This method aims to organize a workspace to boost efficiency and effectiveness, including identifying and storing items used and maintaining area order.

Layout Improvement

Layout improvements focus on resolving delivery time issues caused by a poor layout in an organization.
A cellularization plan can organize the work order in the same area.
Brainstorming techniques are beneficial for deriving solutions by gathering ideas spontaneously.

Additional Lean Manufacturing Techniques

Andon: A lean manufacturing system to notify workers, managers, and maintenance personnel of quality or process problems.
U-line: A layout arrangement where machinery is organized in a U-shape.
Cell production line: A form of mass production that divides work into teams called "cells."
Total Productive Maintenance (TPM): A method of physical asset management focused on improving manufacturing machinery.

TPM Pillars

The eight pillars of TPM are focused on proactive and preventative techniques to improve equipment reliability.

Other Lean Techniques

Early/equipment management: Focuses on eliminating losses and making defect-free production easier.
Safety, health, and environmental conditions: Improve workplace conditions through training initiatives and employee morale initiatives.
Administrative and office TPM: Uses TPM tools to improve support and increase employee moral.
