the decrease in the quality of spreadsheets due to lack of spreadsheet designing. Which in turn affects the decision making and accuracy of the spreadsheet

1. IMPACT OF LACK OF
SPREADSHEET DESIGN SKILLS
ON SPREADSHEET ACCURACY
AND DECISION MAKING

2. INTRODUCTION
• Spreadsheets have become an
indispensable tool in today's data-
driven world
• They help in analyze and interpret data
of an individual or organization
• The design of these spreadsheets
plays an important role in various
industries and deciplines

3. SPREADSHEET DESIGN
• As spreadsheet is really important to a group or
organization, so is the design to it. It is as equally
important as the actual thing
• A good spreadsheet design allows an organization or
group to understand themselves of how good they are
doing
• A bad design is a serious problem as it affects and
impacts a lot of things.
• Here we focus mainly on design accuracy and decision
making

4. IMPACT ON ACCURACY
• The main factors affecting the accuracy are
Formula Errors :
• these are backbone of spreadsheet calculations.
• Incorrect or inconsistence use of formula usage lead to formula errors
• According to a study by Panko (2013), formula errors occur in approximately
88% of spreadsheets, with an average of 1 error for every 20 cells
containing formulas.

5. Data-entry Errors :
• Data entry is a critical step in spreadsheet design, and errors
in data entry can result in inaccurate calculations and analysis
• Lack of skills in data validation, data cleansing, and data
formatting can lead to data entry errors
• Lack of skills in data validation, data cleansing, and data
formatting can lead to data entry errors,

6. Lack of documentation and Formatting :
• Lack of documentation and formatting leads to accuracy
loss and confusion
• Inaccurate analysis and inconsistent formatting makes the
spread sheet to lose its credibility
• Lack of credibility leads to decrease in accuracy

7. IMPACT ON DECISION MAKING
• These factor could lead downfall of an organization. A single
wrong Decision can bring an successful org/company to
bankruptcy.
• The main factors affecting it are
• Incorrect Analysis
• The inaccuracy in spreadsheet data leads to incorrect
analysis on which decision makers rely to
make beneficial decisions.
• Wrong decisions lead to Financial losses, missed
opportunities and other negative consequences

8. Loss of Credibility:
• lack of spreadsheet design skills can result in inaccurate data,
formulas, or formatting, leading to incorrect analysis and
conclusions
• Frequent errors in accuracy and data makes the decision
makers to lose their confidence on the validity of the
spreadsheet
• This makes the very point of spreadsheet useless

9. Time and resource wastage:
• A very badly design of spreadsheet takes a lot of time and
resource to correct
• This leads to delay in decision making and follow
procedures

10. WAYS FOR
EFFECTIVE
DESIGN OF
SPREADSHEE
T
Spreadsheet design plays a critical
role in ensuring the accuracy and
reliability of spreadsheet-based tasks.
Hence a good design is necessary

11. BEST PRACTICES FOR SPREADSHEET
DESIGN
• Structured Data Entry is necessary to make calculations
and analysis easier
• It ensures a consistency in data types and entry
• Designing and providing formula references and
appropriate functions
• These helps to produce error-free and grasp on the,

12. • Uniform formatting provides and increases readability and
interpretation to data
• A Good documentation is necessary should include
justifications of any assumptions, data sources, and
calculations.
• Data validation techniques are required to ensure data
accuracy and checks and deletes or avoids false or invalid
data

13. RECOMMENDATION
FOR SPREADSHEET
DESIGN
This section deals with A Few
things are to be noted but not
really necessary

14. The following are recommended to include while designing a
spreadsheet
• It is advised to keep it simple as it increases usability and
reduces errors
• To make it easier, choosing of a good Template is
recommended or can design their own template based on
their requirements
• It is advised to test and verify the spreadsheet calculations
and formulas before hand
• To preserve accuracy and be up-to-date be sure to review
them every now and then whenever you update
