Operational teams process hundreds of tickets daily. Standard Kanban boards break down under such conditions. Tasks get lost, SLA is violated, and workflows don't match real processes. Companies lose up to 20% of time on manual task tracking. We specialize in developing custom Task Management systems that accurately reflect your business processes. Our experience: over 10 years building such solutions for logistics, manufacturing, and banking. A custom system pays for itself in 6–8 months through automation. According to client estimates, savings on commercial system licenses amount to up to $5,000 per year, with ROI equivalent to $12,000 in annual savings. In this article—how to design the domain model, set up a workflow with guards, and automate routine tasks to cut processing time by 40%.
What problems does a custom Task Management system solve?
The main pains of operational teams are lost tasks, SLA violations, and inflexibility of off-the-shelf tools. A custom solution solves these by accurately mapping business processes. For example, a configurable workflow with guards prevents invalid transitions, and SLA monitoring with escalation avoids delays. For a logistics client, our bespoke system reduced ticket processing time by 40% and operational costs by 25%. It also integrates with corporate software, reducing manual data entry by 15%.
Designing the domain model for a task management system
The basic task structure contains more fields than usually expected:
CREATE TABLE tasks (
id BIGSERIAL PRIMARY KEY,
title VARCHAR(500) NOT NULL,
description TEXT,
status VARCHAR(50) NOT NULL DEFAULT 'todo',
priority SMALLINT NOT NULL DEFAULT 2, -- 1=low, 2=medium, 3=high, 4=critical
assignee_id BIGINT REFERENCES users(id),
reporter_id BIGINT NOT NULL REFERENCES users(id),
team_id BIGINT REFERENCES teams(id),
due_date DATE,
completed_at TIMESTAMPTZ,
parent_id BIGINT REFERENCES tasks(id),
position INTEGER, -- sort order
metadata JSONB DEFAULT '{}', -- custom fields
created_at TIMESTAMPTZ DEFAULT now()
);
The metadata field (JSONB) solves custom fields without schema changes. Different task types have different field sets: a marketing task includes campaign_id and channel, an HR task has position_id and candidate_name. We index needed fields via CREATE INDEX ON tasks ((metadata->>'campaign_id')). This allows flexible scaling for any business requirement.
Setting up a workflow with guards using XState
The key difference of a custom system from Trello is a configurable workflow with transition rules. Not just dragging a card to any column, but a strict state machine with guards:
- A task can be moved to "In Review" only if an assignee exists
- "Done" requires the "Result" field to be filled
- Transition to "Cancelled" is allowed only for a manager or the reporter
// XState workflow configuration
const taskMachine = createMachine({
id: 'task',
initial: 'todo',
states: {
todo: { on: { START: 'in_progress', CANCEL: 'cancelled' } },
in_progress: { on: { REVIEW: 'in_review', BLOCK: 'blocked' } },
blocked: { on: { UNBLOCK: 'in_progress' } },
in_review: { on: { APPROVE: 'done', REJECT: 'in_progress' } },
done: { on: { REOPEN: 'todo' } },
cancelled: { type: 'final' },
},
});
Workflow configuration is stored in the database as JSON. An administrator edits it via a visual editor. This gives full control over business logic. For more about state machines, see Wikipedia.
Choosing the right views: list, Kanban, table
| View | Key Feature | Tool |
|---|---|---|
| List | Virtualized scroll, grouping, sorting | TanStack Virtual + Table |
| Kanban | Drag-and-drop, client-side transition validation | @dnd-kit/sortable |
| Table | Inline editing, mass row selection | TanStack Table with custom editors |
The task list is the primary view. Performance requirements: virtualized scroll for more than 100 tasks, grouping by any field (assignee, status, priority, tag), multi-field sorting.
Kanban: columns = statuses of the current workflow. Drag-and-drop via @dnd-kit/sortable. When dragging between columns, the allowed transition is checked on the client (before sending the request) so the user sees an error immediately.
Table (spreadsheet view): each task is a row, fields are columns. Inline editing. Mass operations: select 20 tasks, assign an assignee, change deadline. Implemented via TanStack Table with row selection and custom cell editors.
Implementing mass operations and automation
Mass operations—often overlooked feature that speeds up work 3x. Examples:
- Reassign a group of tasks to another performer
- Mass close by filter (all tasks older than 30 days in "On Hold" status)
- Copy/move tasks between projects or teams
Automation is based on triggered rules: "If a task is not taken within 2 hours after assignment—remind the performer and notify the manager." Implementation via scheduled jobs (Laravel Scheduler) that query tasks by conditions and perform actions. Automation rules are stored in the DB, editable through UI—condition (trigger) + action.
Common automation pitfalls
- Forgetting to configure escalation conditions for different priority levels
- Not testing triggers on test tasks before going live
- Ignoring night mode—notifications sent at 3 AM
SLA control and escalation implementation
SLA control is critical for operational systems: a task must be picked up within N hours of creation. Implementation:
// Laravel Job, dispatched to queue with delay
class CheckTaskSlaJob implements ShouldQueue
{
public function handle(): void
{
$overdueTask = Task::query()
->where('status', 'todo')
->where('created_at', '<', now()->subHours($this->slaHours))
->whereNull('assignee_id')
->get();
foreach ($overdueTask as $task) {
Notification::send($task->team->managers, new SlaBreachedNotification($task));
}
}
}
The escalation matrix is configured in the admin panel: if task pickup time exceeds 1 hour—email to performer, 4 hours—email + Slack to manager, 8 hours—notification to department head. This ensures critical delays are not missed. Automating SLA control cuts response time by 30% and reduces overdue tasks by 50%.
