1. Introduction

Traditional software development often suffers from unpredictable elements and subjective decision-making. Predictive Software Engineering (PSE) addresses this issue by introducing a set of seven principles, informed by over 29 years of experience. These principles guide development teams towards a more standardized, controlled, and transparent approach, transforming software creation into a precise and predictable engineering endeavor.

2. Meaningful customer care

Customer-centricity remains the cornerstone of success for any business, regardless of its market orientation (B2B, B2C, etc.). Customer satisfaction, brand loyalty, and ultimately, customer acquisition volume collectively define an organization’s success. When an organization’s offerings fail to resonate with target audiences and translate into commercial success, it signifies that it has not yet maximized its potential.

Therefore, to objectively assess progress towards organizational goals, measuring customer satisfaction and feedback through key performance indicators (KPIs) becomes paramount. Should these metrics reveal an unfavorable trajectory, the focus should promptly shift towards transforming dissatisfied customers into ardent brand advocates. This objective can be achieved through the implementation of eight key strategies:

1. Streamline the onboarding process.

2. Offer a dedicated customer portal for easy access and engagement.

3. Establish a clear governance model for efficient issue resolution.

4. Define a transparent escalation path for handling complex concerns.

5. Implement early problem discovery methods to proactively address issues.

6. Conduct comprehensive analysis of customer complaints to identify root causes.

7. Proactively manage customer satisfaction through consistent monitoring and engagement.

8. Set realistic expectations to avoid disappointment and build trust.

3. Transparent end-to-end control

Transparency, characterized by openness, trust, and cooperation, remains a scarce commodity in the contemporary business landscape. Despite its relative rarity, achieving transparency offers significant advantages. Stakeholders, particularly clients, perceive transparent organizations as less risk-prone and more reliable entities, fostering a collaborative environment conducive to long-term success. This paper explores the multifaceted approach required to cultivate transparency within organizations, both internally and externally.
