The Flowchart is one of the 7 basic quality control tools, as for everybody’s information the 7 basic quality tools are the tools for problem-solving situations, tracking, monitoring, and analyzing data.
According to CQE Hand book “95 percent of quality-related problems can be solved with seven fundamental qualitative tools.”
I have a deep interest in discussing here these quality tools because these might help address problems that might appear during the process of the work in construction or project site and eventually could be prevented.
Here is the first of seven (7) basic quality control tools.
1. Flowchart
A flowchart is a diagram that shows the step-by-step flow of operation to get a solution to a problem or to figure out the correct sequence of the process.
Flowchart is used in designing and documenting complex programs. It helps visualize what is going on and what will be processed, and people will better understand the process.
Here are the outputs of Flowchart.
A. Tracking the process flow
- Like the process flow of documents such as drawing, material submittal, and other related documents. The system of the project as well.
B. Helping with decision making
C. Highlighting the important steps
D. Depicting the structure of the process.
E. Understanding the system flow of the process.
Below is a sample Flowchart for the process of drawing distribution.
Flowchart
If you desire to make a flowchart, below are the symbols to consider.
Flowchart symbols
 | Rectangular Fillet | The general symbol used to indicate the beginning and end of the process. |
 | Parallelogram | The symbol Use to indicate the data. |
 | Diamond | The symbol that denotes a decision in the process. |
 | Rectangle | The general symbol use to depict the processing operation. |
 | Circle | Sometimes used to indicate the start and end of the process. |
 | Flow line | A line with an arrowhead is the symbol that shows the direction of the stages in a process. The flow line connects the elements of the process. |
In summary, a flowchart is useful in determining the workflow of processes such as material submittal, drawings for approval, communications, etc.

Hello Noel thanks for your valuable information, please I need to know the quality engineer stage is it after consultant approval for shop drawing fabrication?
Hi Bishoy,
This is the task of a Quality Engineer is to ensure that all the drawings are approved by the Consultant before starting works on site.
Please upload another six tools
I will make it soon, just wait for that.
Cause-and-effect diagram (also called Ishikawa or fishbone chart): Identifies many possible causes for an effect or problem and sorts ideas into useful categories.
Check sheet: A structured, prepared form for collecting and analyzing data; a generic tool that can be adapted for a wide variety of purposes.
Control charts: Graphs used to study how a process changes over time.
Histogram: The most commonly used graph for showing frequency distributions, or how often each different value in a set of data occurs.
Pareto chart: Shows on a bar graph which factors are more significant.
Scatter diagram: Graphs pairs of numerical data, one variable on each axis, to look for a relationship.
Stratification: A technique that separates data gathered from a variety of sources so that patterns can be seen (some lists replace “stratification” with “flowchart” or “run chart”).
Very Good Information.
Please create your blog and share your wonderful knowledge so that we can learn and understand the basics of PM and QA?/QC.
Still waiting
Where is another (6 ) tools? Here it’s just shown flowchart.
I will publish later, just wait for that I’m currently preparing article related to ISO.
Sir, ask ko lang po if meron ding software for QA/QC like Primavera P6 for scheduling and planning. Thanks po.
Wala pa akong nakitang software para sa QA/QC. Welcome John.
Sa mga trainings po at certifications ano po kinukuha ng mga QA/QC Engineer? Pwede din po ba sa atin maging PMP?
Kumuha ka ng, una Lead Auditor Training, tapos CQE. I suggest PMP kung Manager ka na or mataas na ang experience mo. Mahal ang mga trainings sa atin kaya advantage kung dito ka sa abroad.
Thank you Sir for a very informative blog site..
Welcome John. And thank you for coming across to my blog.
