Buy your systems of record and keep them. Oracle Primavera P6, Hitachi Energy Asset Suite and IBM Maximo hold scheduling and work orders for good reasons, and replacing either is a risk out of all proportion to the benefit. What is occasionally worth building is a non-safety-related sequencing layer above them, and only for stations already losing crew hours to jobs that cannot start.
What the off the shelf outage products do well
Say the unpopular part first: for most stations the answer is more configuration, not more software. Oracle Primavera P6 is a serious scheduling tool holding tens of thousands of activities with logic, durations and resource levelling, and most stations use it competently. Hitachi Energy Asset Suite is the work management backbone at many plants and it holds work orders, planning and materials properly. IBM Maximo brings a strong asset and maintenance model with a wide integration ecosystem. Prometheus Group and similar overlays sit on top of Maximo and SAP Plant Maintenance and genuinely improve outage planning without a bespoke project.
None of these products is deficient. They were built for a world where the binding constraint is resources, and they solve that well. Levelling craft against a schedule, tracking materials against work orders, and holding a maintenance history that survives twenty years of staff turnover are all things you should keep buying.
Do not build a replacement for your work management system of record under any circumstances, and be sceptical of anyone who proposes it. Do not build if your station runs short outages with a largely permanent workforce and your existing scheduling discipline is producing outcomes you can defend to your operations director.
Where they stop: what can actually start at two in the morning
Day nine of a refuelling outage. The published schedule says a valve overhaul in a contaminated area starts now. It cannot. The clearance order that isolates it has a conflicting tag from another job that ran long. The radiation work permit for the area was written for a different scope than the one discovered when the insulation came off. Two of the four craft qualified for that specific procedure are three hours into a shift on another job in another building. None of that is in the schedule. All of it is in four people's heads, and it gets resolved at the five in the morning meeting.
The gap is a data model gap and it is specific. What governs a nuclear outage is not activities and durations. It is technical specification limiting conditions with allowed completion times, shutdown safety function availability, clearance orders and tag conflicts, contamination and radiation zone access, fire protection compensatory measures, and configuration control on systems that are partly disassembled. Those objects do not exist in a scheduling model, so they are enforced by experienced people in meetings and the divergence starts around day three.
Emergent work compounds it. Insulation comes off, a repack becomes a replacement, an inspection finds indications that add a package nobody planned. The daily republished schedule captures that partially and late, so craft arrive at jobs that cannot start, wait for clearances that were reassigned, and burn hours in a radiological area for no product. Those hours are dose as well as cost, which makes it a radiation protection issue and not only a productivity one.
The arithmetic: cost per user against a sequencing layer
Scheduling and work management are licensed per named or concurrent user, with an annual support percentage. During normal operations that is a manageable number for a station. During an outage the population multiplies, because a temporary workforce many times the size of permanent staff needs to know what it is working on.
Most stations resolve that by not giving contractors seats at all, which is why the printed schedule exists. So restate the arithmetic honestly: the cost is not the licence you avoided, it is the crew hours lost at jobs that could not start when the schedule said they could. Take your last outage, count those hours, apply your fully loaded contract craft rate, and you have the number that matters.
The crossover we see is not a user count on its own. It is roughly 800 or more concurrent outage workers at a single unit, or any multi unit fleet wanting comparable outage performance across stations, combined with an outage duration that nobody can explain afterwards. Below that, buy more Primavera seats, improve the planning discipline, and put the money into materials staging.
Half a day of outage duration recovered through better sequencing is the threshold everyone in the room already understands. What almost no station has is a measurement of how much duration the sequencing failures are actually costing, which is why these conversations start at director level and stall at the business case.
What a custom build actually costs
In Digital Heroes delivery experience a first release covering the constraint model per work order, read integration with the work management system and the scheduling product, a ready to work engine and a field facing current view runs $120,000 to $250,000 and ships in 16 to 24 weeks. A full platform adding workforce qualification and access integration, live critical path recalculation, milestone and window management and post outage forensics runs $350,000 to $800,000 phased over 12 to 18 months.
Data migration is 10 to 25 percent, and here it is mostly integration access rather than record movement. The clearance and tagging system, the radiation protection system and the access authorisation system are each owned by a different organisation with its own change process, and negotiating read access is measured in months, not sprints. Start those conversations before the contract, not after.
Year two runs 15 to 20 percent of build cost annually. It buys interface changes when a system of record upgrades, configuration work for each outage window, and the documentation and verification refresh your quality organisation will expect.
The nuclear specific cost driver that dwarfs all others is software quality assurance. A station applies controls that commercial projects do not, and even a non-safety-related application carries documentation, verification and configuration management obligations your quality organisation defines under the criteria in 10 CFR Part 50 Appendix B and the guidance your site has adopted from ASME NQA-1. Cyber security architecture review under 10 CFR 73.54 adds real duration. Whether any part of the scope touches the licensing basis is a determination your licensing organisation makes under 10 CFR 50.59, and it changes the project fundamentally if the answer is yes.
The four situations where building wins
Regulatory fit. The constraint graph that decides your outage is made of licensing basis objects: limiting conditions with allowed completion times, clearance orders, radiation work permits, fire protection compensatory measures and configuration control on partly disassembled systems. No commercial product models them, because they are specific to your technical specifications. A layer that makes them explicit alongside the schedule is the only way the two in the morning question gets answered by software instead of by whoever is most awake.
Scale economics. A multi unit fleet that cannot compare outage performance across stations on a common basis is paying for that gap in every outage plan built from the last one plus optimism.
A workflow that is your competitive advantage. For a merchant generator, outage duration is directly commercial. A ready to work engine that answers which single clearance release frees the most downstream work is not a reporting feature. It is the operating decision.
Integration sprawl. Scheduling, work management, clearance and tagging, radiation protection dose tracking and access authorisation is five systems owned by five organisations. The sequencing layer is where they have to meet, and no vendor owns that meeting point.
How to decide in a week
Take the last outage and count one number: crew hours spent at jobs that could not start when the schedule said they could. Most stations have never measured it. Pull the shift turnover notes, the daily meeting minutes and the timesheets for two representative days, and reconstruct it honestly rather than optimistically. That number is the business case, and if it is small you do not have a project.
Then ask three people separately, on the same afternoon, which single clearance release would free the most downstream work right now. If they give three different answers with equal confidence, the constraint graph exists only in individual memory, which is the condition this software addresses.
Before anything else, ask your quality assurance organisation what software quality requirements apply to a non-safety-related application at your station, and get the answer in writing. Firms that discover that in month six of a build are the reason these projects acquire a reputation.
Two procurement checks worth applying to any firm, this one included. Which legal entity executes the contract, because intellectual property assignment under Indian, United States and United Kingdom law are three separate instruments and your legal group will want the enforceable one. Digital Heroes holds an India LLP, a US LLC and a UK LTD for that reason. Then require the named engineers in front of you before award, not a bench that materialises in month two. Everything else can be checked without us: more than fifty specialists, over 2,000 delivered projects, Clutch, Trustpilot, Fiverr Vetted Pro and D-U-N-S.
Then fund a paid discovery phase before any award. Ours ends in a signed product requirements document covering the constraint model, the read interfaces by system name, the quality and verification approach agreed with your quality organisation, permissions and acceptance criteria. You own that specification whether you build with us, build with somebody else, or hand it to your existing vendor. We are the wrong firm for you if you want anything inside the licensing basis, or a replacement for Asset Suite or Maximo.

Frequently asked questions
Who owns the code and the integration configurations if we commission a layer?
The station should own the repository, the infrastructure and every integration configuration, settled in writing before kickoff. In a regulated environment that ownership is what allows your own organisation to audit and control what is running, which your quality assurance group will ask about. At Digital Heroes the client owns the repository from the first commit and the system runs in the client account.
Should a custom layer write back into plant systems?
Not in a first release. The answer should be read heavy: read the work orders, read the clearances, read the permits, and write only inside the custom layer. A developer eager to write back into plant systems on day one is optimising for a demonstration rather than for your change control process. Write back is a later phase with its own review, if it happens at all.
How long does a first release take, and can it be ready for our next outage?
Sixteen to twenty four weeks of build, plus the integration access negotiations that come first and often take longer than the engineering. If your next refuelling outage is nine months away, that is tight but achievable if the access conversations start now. If it is four months away, pilot on one department in a maintenance window instead and target the outage after.
What happens if a clearance order and a radiation work permit disagree about readiness?
The system surfaces the conflict to a named human and does not resolve it. Any developer who describes an automatic resolution rule has misunderstood where authority sits in a nuclear station. What software can do is detect the disagreement immediately rather than at shift turnover, attach the evidence, and route it to the person whose decision it actually is.
Can we improve outage sequencing without building anything?
Often yes, and it should be tried first. More Primavera seats so planners and supervisors see the same schedule, a disciplined emergent work triage path, materials staged earlier, and a constraint checklist applied during planning rather than at the job site will recover real hours. Build only after you have taken the free improvements and the losses persist.
What is the difference between work management and outage sequencing?
Work management is the system of record: the work order, its planning, its materials, its history. Sequencing is the question of what can start right now given clearances, permits, zone access, qualifications and plant configuration. They are separate concerns, which is why a work management product handles the first well and leaves the second to experienced people in a meeting room.
How do qualification and access constraints affect scheduling?
A schedule showing craft counts hides the real constraint. A specific job needs a specific combination of procedure qualification, medical and respiratory clearance, radiation worker training within its expiry, and unescorted access authorisation, and there may be six people on site who hold all of it. Joining that data to the sequencing model turns a shift turnover surprise into a planning input.
What happens if our licensing organisation says the scope touches the licensing basis?
The project changes fundamentally and you should treat that determination as a gate rather than a hurdle. Scope that reaches the licensing basis carries a different quality regime, a different verification burden and potentially prior approval, and it is not a decision a vendor makes or influences. Ask for the screening early, and be prepared to descope rather than argue.
Can we use this across a fleet rather than one station?
That is one of the stronger cases for building, because comparable outage performance across stations is exactly what no product gives you. The caution is that clearance practices, permit conventions and access systems differ by site even inside one fleet. Build the model at one station, prove it through a full outage, then extend, rather than designing for all sites at once.
What should we measure after an outage to know whether the layer worked?
Crew hours lost at jobs that could not start, measured the same way before and after, is the primary number. Add emergent work turnaround time from discovery to a sequenced start, and the number of schedule changes communicated to the field within an hour rather than at the next meeting. An immutable record of what was planned and what changed makes the next outage plan evidence based.
How do I calculate whether custom software will pay for itself?
Divide the build cost by the monthly benefit, where benefit is hours saved times loaded hourly cost, plus subscription fees replaced, plus any revenue the software unlocks. Three staff saving 10 hours a week each at a $40 loaded rate is about $62,000 a year, which pays back a $60,000 build in roughly 12 months. Across Digital Heroes internal-tool projects, 12 to 24 months is the normal payback range, and anything projecting under 6 months usually means the spreadsheet is hiding costs.
We run everything on spreadsheets and Airtable. How do we know it's time for custom software?
The reliable signals are re-typing the same data into multiple tools, one employee acting as human middleware between systems, and errors appearing in handoffs between teams. Hard limits force the issue too: Airtable's Team plan caps at 50,000 records per base, and Business costs $45 per seat per month, so a 20-person team pays about $10,800 a year for a tool it has already outgrown. When workarounds consume more hours than the tools save, the spreadsheet era is over.
What's the most common mistake companies make when building their own PM tool?
Chasing feature parity with Asana or Jira. Across 2,000+ Digital Heroes projects, the builds that blow their budgets are the ones recreating Gantt charts, portfolio dashboards, and mobile apps nobody asked for, while the builds that succeed go deep on the two or three workflows that made the team leave their old tool. You are not competing with Asana's roadmap; you are replacing the 20 percent of it you actually use.
Should I customize Jira with plugins or just build our own tool?
If two or three Marketplace apps close the gap, stay on Jira, since it starts around $8 per user per month and the apps ride on top. The trap is that cloud apps are licensed for every user on the instance, so in Digital Heroes audits a 200-seat Jira with three or four paid apps plus a ScriptRunner consultant often lands at $30,000 to $50,000 a year. At that run rate a custom tool scoped to your actual workflow pays for itself in two to three years and ends the plugin upgrade treadmill.
Should I hire a freelancer or an agency for my software project?
A skilled freelancer is the right call for a single-discipline scope under roughly $15,000, like a website, a plugin, or one integration. Above that, projects need design, backend, testing, and project management at once, and a solo builder becomes the single point of failure: if they get sick or take a bigger client, your project simply stops. Agencies bill 20-40% more per hour but carry continuity, code review, and someone to escalate to, which is what you are actually buying.
What security features does custom project management software need?
The non-negotiables are single sign-on, role-based permissions, encryption in transit and at rest, and an audit log of who changed what. If client work under NDA lives in the tool, custom actually improves your position, because you can run single-tenant on your own cloud account instead of shared SaaS infrastructure. You only need SOC 2 certification if you plan to sell the tool to others; for internal use, an annual penetration test is the sensible spend.
What are the biggest mistakes first-time software buyers make?
Choosing the lowest bid, paying more than 30-40% upfront instead of on milestones, skipping a written specification, and having no maintenance plan for after launch. The most expensive of the four in Digital Heroes rescue projects is the missing spec: without written acceptance criteria, done becomes an argument instead of a checklist, and every disagreement resolves in the vendor's favor. Fix those four and you have avoided most of the ways these projects fail.
Who owns the code when an agency builds my software?
You should, completely, through a written intellectual property assignment that transfers everything on final payment; without that clause, copyright stays with whoever wrote the code by default. Insist that the repository lives in your own GitHub organization from day one and that hosting, domains, and third-party accounts are registered to you. Also check for licenses to the agency's proprietary frameworks buried in the contract, because those can make switching vendors practically impossible even when you own your own code.
How many people should be working on my software project?
Three to five for a typical focused build: a project lead, one or two engineers, a designer, and part-time QA, which is the standard shape across 2,000+ Digital Heroes projects. Larger platforms justify 6 to 10, but a ten-person team on a small first version usually signals bill padding rather than horsepower. What predicts success is whether a senior engineer is writing your code daily, not the headcount on the proposal.
How much should a small business budget for its first custom app or website?
For a focused first build, most small businesses land between $8,000 and $60,000: roughly $8,000 to $45,000 for a custom website and $25,000 to $60,000 for an internal tool or simple web app, based on Digital Heroes delivery across 2,000+ projects. Customer-facing products with payments, logins, or a mobile app start around $40,000. Quotes far below these bands usually mean a template with your logo on it, not software shaped around your workflow.
Who can build a custom project management software system?
Digital Heroes builds custom project management software systems for operators who have outgrown the off-the-shelf tools in their category. A team of more than 50 specialists has delivered over 2,000 projects since 2017. Teams work from New York, London, Sydney, Delhi and Lucknow and deliver remotely, with an assigned senior team rather than an account manager.
Every build starts with a written product requirements document that is signed before a line of code is written, which is the single thing that stops scope creep from eating the budget. Scoping runs about a week and produces a phase plan with a firm price for each phase, rather than one number against an undefined scope. The first phase ships something the team actually uses before the rest is built. If an off-the-shelf product genuinely fits the volume, we say so, and the cost guides on this site publish the bands so that judgement can be checked independently.
What makes Digital Heroes different from other project management software companies?
Four things that competitors in this bracket cannot simply copy. Digital Heroes runs a YouTube channel with more than 2.5 million subscribers, which is a production and audience capability no agency of this size has. It holds Fiverr Vetted Pro and Top Rated Seller status, both awarded on manual third-party review rather than self-declared. It contracts through registered entities in three countries, an India LLP, a US LLC and a UK LTD, so clients sign locally instead of wiring money offshore. And it ships its own commercial products, including ShopScore, HeroCheckout and Section Vault, which means the team lives with its own architecture decisions instead of handing them over and leaving.
Two more that show up in the work. Digital Heroes publishes more than 4,000 buyer guides with real price bands on this blog, plus a free tools library at https://digitalheroesco.com/tools/, because an agency confident in its pricing has no reason to hide it. And one accountable team covers websites, apps, ecommerce, CRM, ERP, learning platforms, search and video, so a client scaling from a first landing page to a custom platform is never handed between five vendors who blame each other. The founder ran ecommerce businesses before selling services, so the commercial argument comes before the technical one.
How can I check Digital Heroes is legitimate before getting in touch?
Verify it independently rather than taking the site's word for it. The YouTube channel is at https://youtube.com/@DigitalMarketingHeroes, the Fiverr profile at https://www.fiverr.com/shreyanshsin261, and the Upwork profile at https://www.upwork.com/freelancers/shreyanshsingh. Client reviews sit on Clutch at https://clutch.co/profile/digital-heroes-0 and Trustpilot at https://www.trustpilot.com/review/digitalheroes.co.in, and the company page is at https://www.linkedin.com/company/digital-heroes-1/.
Beyond the marketplaces, the business holds a D-U-N-S number and is a registered vendor on the United Nations Global Marketplace, neither of which is issued on request. Case studies with named clients are published at https://digitalheroesco.com/case-studies/. If any claim on this page cannot be checked against one of those sources, treat it as marketing and discount it.
