Five consulting habits worth stealing, whatever your job

What is happening

Much of what makes consultants effective is not secret knowledge but working habits developed under time pressure and client scrutiny. They decide what they think early, plan the final document before doing the analysis, spend effort where it changes the answer, test every finding for its implication, and write down what they learn each week. None of these needs a consulting title.

The habits are especially valuable in Indonesian workplaces where junior staff are expected to execute rather than to propose. A junior analyst who brings a clear draft answer and a plan for testing it is easy for a senior manager to say yes to, and it builds the reputation for judgement that drives later promotion.

Why it matters

These habits make your work easier to direct and easier to trust, which is what most managers mean when they call someone “ready for more”.

The framework

Five habits to steal

  1. The day-one answerWrite your best guess at the answer on the first day of any task, then work to test it.
  2. The ghost deckWrite the slide titles or report headings of the final document before analysis. Each title is a hypothesis.
  3. Eighty-twenty effortAsk which 20% of the analysis would change the decision, and do that part first and best.
  4. The so-what testAfter every finding, ask “so what?” until the answer is an action someone could take.
  5. The Friday synthesisEach week, write three lines: what we now believe, what changed, what we test next.

What this means for you

Fresh graduateUse the ghost deck on your first big assignment and show it to your manager before you start. You will avoid a week of wasted work.
Early professionalThe Friday synthesis, sent to your manager, is the simplest way to make your thinking visible.
Experienced professionalAsk your team for the day-one answer and the ghost deck on every new piece of work. Review the titles, not the spreadsheets.

What to do

  1. Pick your current main task and write the day-one answer in one sentence.
  2. Draft five slide titles that would prove it, then do the drill below.
  3. Run the so-what test on the last three findings you shared at work.
  4. Start a Friday synthesis this week and keep it for a month.

Practice drill

Build a ghost deck in ten minutes10 min, timed

Your manager asks: “Should we move our customer-service team from email to WhatsApp Business?” Before any analysis, write the five slide titles of your final recommendation as complete sentences with blanks for numbers.

  1. Slide 1 is the recommendation.
  2. Each other slide proves one reason or addresses one risk.
Show a model answer

(1) “We recommend moving first-line service to WhatsApp Business within [X] months, keeping email for formal complaints.” (2) “Most customers already contact us by chat: [Y]% of enquiries last quarter.” (3) “Response time could fall from [A] hours to [B] minutes with the same team.”

(4) “The main risks are data protection and record-keeping, addressed by [controls].” (5) “A two-month pilot with one product line tests the case before full roll-out.” Every blank is now a specific analysis to run, and nothing else needs doing first.
