Advantage / Indigo / The Summary
Batteries, inverters and island grids on one violet-ruled sheet
Indigo / The Summary is an Advantage design that reads like the paper a risk and safety committee receives before a technical item is discussed. Its demonstration leader is Intan Teo, a fictional chief technology officer at Lautaneri Energy, a privately held Singapore company running thirty-eight solar-and-battery plants on small island grids in the Philippines and eastern Indonesia, plus fourteen factory battery installations. A briefing format suits her because her record is measured in temperatures, sites, repair hours and write-offs rather than in public profile.
The masthead and the sheet: her claim beside a small square portrait
A six-pixel violet rule runs along the top edge of the masthead, with Intan's name as the wordmark, Chief Technology Officer beside it and the seven page links held on one line to the right. Beneath sits a single near-white sheet with a fine lilac border, opened by the eyebrow Executive summary / Personal profile. Her large Lora headline reads Keeping small island grids steady after sunset, set beside a 120-pixel square crop of her portrait. Below a rule comes her one-line profile about the battery, the controller and the remote link, then her board availability and a Start a conversation link.
Two numbered columns, then the figures and the opening of each case
Under the claim the sheet divides into a wide column labelled 01 / Leadership approach, which carries her conviction that an island plant has no neighbour to lean on, and a narrower column labelled 02 / Areas of responsibility, listing her five disciplines from battery derating to build-or-buy rules for fleet software. A lilac band then holds four figures: 52 plants, 412 MWh of island storage, US$118m of company revenue, captioned as not a technology budget, and an 86-person team. Evidence from practice pairs each case title with its first sentence only, so a director meets a cooling unit failing at 15:40 in April 2024, a supplier's hidden cellular link and an eight-year-old controller as situations before reading any result.
Why violet-indigo, Lora and Work Sans fit a power engineer
The page ground is a pale lavender grey, the sheet almost white and the fact panels a soft lilac. Text is a deep aubergine; the violet-indigo accent is kept for the masthead rule, column labels, eyebrows and links. Energy companies often market themselves in leaf green or sunrise orange, and Intan's readers, chairs of infrastructure and industrial companies, fund-nominated directors and search advisers in Singapore, would discount that palette as sales material. Indigo reads as sober and technical. The renderer loads Lora for her headline, headings, case titles and figures, and Work Sans for body text, navigation and the ten-pixel uppercase labels, so values such as 52°C and 410 inverters stay crisp.
Career rows and a three-column committee briefing
Her career page, headed From cable schedules to a fleet control room, prints each of six appointments as a ruled row: title and company on the left, dates aligned right, then a lilac panel listing sector, ownership, scale, employees, geography, reporting line, team and budget. A search adviser can trace her through substation relays, battery rooms and 2,300 tower sites. The readiness page opens with her contribution, then sets three columns between heavy aubergine rules: the two committees she would join, with no chair row because she claims none; her twenty days, zero directorships and sought seat; and her learning, including a databank status that she states does not apply to her market. Exposure, judgement, first year, conflicts and independence follow.
Expertise, impact, contact and the phone view
The expertise page numbers her five areas, each written as a rule with its price, such as derating authority held outside the commercial line. The impact page repeats the figure band and prints all three cases in full, so US$1.3 million of availability credits, repair times that rose from nine hours to fifteen and a US$1.9 million write-off sit beside the improvements. Contact repeats her one-line profile above the enquiry guidance. On a phone the portrait shrinks to 70 pixels, the home and readiness columns stack, and appointment dates move beneath each title.
Other leaders who would read well on this sheet
The Summary suits technical executives whose authority rests on incidents handled and costs admitted: a water operator's engineering director, a port's head of systems, a tower company's technology chief or a hospital group's facilities executive. It also helps a first-time director candidate who must show that presenting to a committee is not the same as sitting on one.
Questions about this design
- What should the opening sentence of each case contain in this layout?
- Only that sentence appears on the summary sheet, so make it a dated situation with a measurable detail. Intan's first case names a time, a month and a cell temperature, which tells a director the record that follows is factual.
- Does an indigo palette undersell an energy-transition story?
- No. The accent is confined to rules, labels and links, while body text stays dark on near-white. For a technology chief the restraint signals governance; the solar and storage figures carry the transition story without colour doing it for them.
- How should a technology executive describe grid-code duties here?
- Describe the behaviour the requirements demand, such as frequency response, ramp limits and riding through brief voltage dips, rather than citing clause numbers you cannot verify. Intan explains them in general terms and keeps the grid operator's own answers on file.
- What material should a CTO prepare before choosing The Summary?
- Gather an incident or near miss you reported upward, a supplier or platform choice with its cost, and a safety decision that someone senior opposed. Add dated appointments with team sizes and budgets, a conviction short enough for column 01 and the responsibilities for column 02. No essays are required on this plan.
