Turn four stated requirements into an edition you can defend

short · 25 min · Objective 1.1

Task

Take four written requirement sets and decide which Windows edition each one needs, naming the specific feature that forces the answer. The skill being practised is the one the exam scores: not knowing the feature matrix, but being able to say which single requirement excluded the cheaper edition.

Steps

  1. Write lab/editions/features.csv with header feature,home,pro,enterprise,note covering at least six features that differ between editions, with yes/no in each column, cited from the vendor's own comparison rather than from memory.
  2. Write four requirement sets of your own in lab/editions/cases.md, each two or three sentences describing an organisation. At least one must be satisfied by Home.
  3. Write lab/editions/decisions.csv with header case,edition,forcing_requirement,feature giving your answer for each case and the single requirement that decided it.
  4. For any case you answered Enterprise, add a line to lab/editions/decisions.csv note field stating what Enterprise adds that Pro does not, or change the answer to Pro.
  5. Write lab/editions/licensing.csv with header type,transferable,tied_to,failure_mode covering retail, OEM, volume and subscription.

Verify

awk -F, 'NR>1 && NF>=5 {n++} END {print n" feature row(s)"}' lab/editions/features.csv
awk -F, 'NR>1 && NF>=4 {n++} END {print n" decision(s)"}' lab/editions/decisions.csv
awk -F, 'NR>1 {print $2}' lab/editions/decisions.csv | sort -u | wc -l
grep -Eic 'home' lab/editions/decisions.csv
awk -F, 'NR>1 && NF>=4 {n++} END {print n" licence type(s)"}' lab/editions/licensing.csv

Six or more features, four decisions, at least two distinct editions across them, and at least one Home answer. A set of four decisions that all say Pro is a set of four cases you wrote to have the same answer.

Notes

The Home answer is the one people avoid because it feels like under-selling. A sole trader with no domain, no central management and no inbound remote access does not need Pro, and recommending it anyway is spending someone else's money.
