Understanding Presenting a technical proposal to an audience in QCE Digital Solutions Unit 3

What it does: Using diagrams and tables is a sub-theme of presenting a proposal: visuals make complex ideas clear for the audience. Answering questions is the final step of presenting a proposal, and good answers refer back to requirements and justified decisions. Adapting to the audience means using language they understand. A non-technical client needs plain language, not jargon. A logical order helps the audience follow your reasoning from the need through to the proposed solution. Justifying decisions means giving reasons linked to the problem, requirements or constraints, not personal preference. Diagrams such as hierarchy charts and IPO charts make structure easy to see. Dense text is hard to take in during a presentation.

Common mistakes: <- assigns a value, but this line needs to compare the audience to "client". It should use the comparison operator: if audience = "client" then. The justification is text, so it must be in quotes. Without quotes the computer reads it as variable names. It should be: reason <- "Less repeated data".

Quick Questions

1. You are presenting a proposed booking app to a client who runs a small business and has no IT background. Which approach is better?

A. Explain it in plain language and define any technical term you need to use ✓

B. Use as much technical jargon as possible to show your expertise

Adapting to the audience means using language they understand. A non-technical client needs plain language, not jargon.

2. Which order is better for presenting a technical proposal?

A. Problem, proposed solution, requirements and constraints, then next steps ✓

B. Random order, jumping between ideas as they come to mind

A logical order helps the audience follow your reasoning from the need through to the proposed solution.

3. You chose a relational database over a spreadsheet for your solution. What should you say to the audience?

A. We chose a relational database because it is the one we wanted to use

B. We chose a relational database because it avoids repeated data and keeps records consistent ✓

Justifying decisions means giving reasons linked to the problem, requirements or constraints, not personal preference.

4. Which visual best helps an audience see how a proposed system is divided into parts?

A. A hierarchy chart showing the sub-problems ✓

B. A slide packed with paragraphs of text describing every part

Diagrams such as hierarchy charts and IPO charts make structure easy to see. Dense text is hard to take in during a presentation.

5. Which is the better way to present the cost constraints and feature comparison of a proposal?

A. Read out every figure aloud without showing anything

B. Put them in a clear table so the audience can compare them quickly ✓

Tables organise comparisons and numbers so the audience can see them at a glance.

Match the Pairs

Adapting to the audience → Choosing plain language and the right level of detail so the people listening, such as a client or manager, can understand the proposal.

Justifying a decision → Giving reasons or evidence for a choice, such as why a database was chosen over a spreadsheet, so the audience can trust the proposal.

Diagrams and tables help the audience see how the proposed solution works and compare options quickly. → Show an IPO chart and a decision matrix on slides

After presenting, the presenter responds to the audience's questions with clear, honest answers linked back to the proposal. → Q&A: Answer 'Why this budget?' using the requirements

Slide text: 'Normalised relational schema with FK constraints' (for a client with no IT background) → Technical jargon is used without explanation, so the audience cannot follow. It should be in plain language for the audience.

Slide: 'We will use a mobile app.' (no reason given) → The decision is stated with no justification. The presenter should explain why, such as linking it to user needs or constraints.

Spot the Error

Question 1

A input audience

B print "Problem and need"

C print "Proposed solution"

D if audience <- "client" then

E print "Plain summary"

F end if

Line D — <- assigns a value, but this line needs to compare the audience to "client". It should use the comparison operator: if audience = "client" then.

Question 2

A decision <- "Use a database"

B reason <- Less repeated data

C print decision + reason

D print "Any questions?"

Line B — The justification is text, so it must be in quotes. Without quotes the computer reads it as variable names. It should be: reason <- "Less repeated data".

Question 3

A diagram <- "hierarchy chart"

B table <- "requirements table"

C print "Slide: " + diagrams

D print "Also: " + table

Line C — The variable is called diagram, not diagrams. The slide line must use the variable that was set up: print "Slide: " + diagram.

Question 4

A while questions < 0 do

B print "Answer clearly"

C questions <- questions - 1

D end while

Line A — The presenter should keep answering while questions remain, so the condition must be questions > 0. With < 0 the loop never runs and no questions are answered.

Question 5

A input level

B if level = "expert"

C print "Show technical detail"

D else

E print "Use plain language"

F end if

Line B — The if line is missing the keyword then. It should be: if level = "expert" then.
